You really enjoy those dvd movies and games and the last thing you need or want is to experience problems with your dvd drive.

To prepare for the possibility of having your dvd drive leaving you out in the cold one morning,we will dicuss problems that may cause dvd failure as well as the procedures you should take to correct these problems.

As with all drives,be sure to double check the failure. If the dvd drive will not read the dvd, try running another dvd in the drive. Make sure the dvd has no scratches and is clean.

Visually inspect the drive if the drive is external and if the drive is enternal,check the computer.Check to see if the computer has good ventilation to help keep it cool.Here are the common dvd problems with their solutions.

DVD DRIVE HAS NO POWER

First..For external drives that have no power,first check to see if anything or anyone has caused the power cord to become unplugged.Rule out the wall outlet by plugging in another device such as a radio and see if it plays.

Second...If youve proven the wall outlet to be good,but you still dont have power,check the surge protector for any signs of damage.If the surge protector is good,check the cord.

Third..If youre certain the surge protector or wall outlet is providing power,double check the cord by plugging it in a few times.If no power is present,you will have to replace the cord or the drive itself.

Internal dvd drives receive their power from the connector from the power supply.Try another connector to the drive. if the internal dvd drive still does not receive power after using another connector,the drive is faulty.

DRIVE HAS POWER BUT TRAY WONT OPEN

You may experience the tray failing to open.Should this happen,press the button a couple times to see if it will open.If the tray fail to open,reboot your computer and try to open the tray.

When rebooting the system,notice the monitor to see if the drive is recognized by the computer.Some systems will not display installed hardware during bootup.If this is the case,you will have to access your BIOS to check if the dvd drive is being registered.

You can also try the manual eject button on the drive to get it to open.Use something very small but firm to press in the pinhole in front of the drive to open the tray.

Shut the computer off and unplug it.Use something like a long paperclip to insert in the pinhole to open the tray. The tray may open a couple inches and you can grab it with your fingers to open it completely.

DRIVE IS NOT RECOGNIZED BY WINDOWS

Be sure the operating system is recognizing the drive by clicking on My Computer.Windows XP will show "drives with removable storage".If your drive is present, highlight the drive,right click and select properties.Click on properties and you should see "this drive is working properly".

If you see another message such as "this drive is not working properly",you may be able to update the device driver.If the drive is not present in My computer,reboot the computer and access the cmos setup.

In the cmos setup,the dvd drive should be present.The drive may not be properly installed or one of the cables have become disconnected if the drive is missing

If you check the drive cables and are certain they are connected correctly,it may be that the data cable is faulty and the drive controller may be at fault.And we cant overlook the fact that the drive itself may be bad.

DRIVE HAS POWER BUT WILL NOT READ DVD

First..try another dvd since a dirty or scratched dvd may not play.If the new dvd fail to play as well,check to see if the operating system is recognizing the drive

Click on My Computer and highlight the dvd drive.Right click and select properties.The statement "This device is working properly" should be present.If not or you see another message,try to update the device driver.

In the My Computer screen,highlight the dvd drive,and select the Properties screen,select Drivers,and then select update device driver.

Another cause may be the Windows Registry is corrupt. You can use software utilities such as PC Bug Doctor to repair your registry. Download this free repair utility at http://www.pcbugdoctor.com/download.html.

To make a backup of your registry with Windows 98, just go to Start, select Run, enter scanregw and click OK. This will run Scanregw.exe.

Restore your registry in Windows 98 by typing scanreg / restore at the Dos Prompt.You can also use.Winrescue XP at http://www.superwin.com/index.htm is a neat little utility for backup and restore of Windows XP.

The dvd drive or writer is an awesome storage and data backup drive.Use it to the fullest to enjoy music,video, audio,and more.Understand everything about this drive before something goes wrong.

Should your audio die on you,check the dvd to be sure it is not dirty or damaged.Look at the audio cable for signs of looseness.Inspect this cable to be sure it is inserted in the connector completely and that is indeed inserted in the correct connector.

If you have a dvd drive,take the time to visit the support web site and download the latest device drivers or patches to keep your drive running at peak performance.

So you have this great digital camera and you’ve taken lots of great photos. Now what Well you could go to a store and have them print your images for you, but isn’t that what you did with film The point of all this great digital technology is that you can print your own photos at home without having to pay someone else to do it. Here are some tips to help you get started:

1. It’ll seem like a lot of money at first but spend the money to get a good printer. Six color at least. Ink jets are wonderful for printing snapshots. You won’t need more than that. Also look around at the computer brands that sell computer packages for digital printing, the printer that they recommend is perfect for printing photos at home.

2. Buy some photo editing software. There are lots of brands out there many of them for pros but you can easily find software under one hundred dollars that will have lots more options than you will ever use. Look for software that has automatic settings so that the computer can automatically color correct, auto focus, brighten, or darken, etc. At least until you learn number 3.

3. Learn your equipment. Take the time play with the settings. Don’t try to print perfect photos right away. Most people with a little time and practice can learn to do basic photo special effects. Give yourself the time to learn.

4. There is one place that you are going to have to spend some money and it’s on paper. You can have a great image but unfortunately you cannot skimp on paper. Get the nice thick glossy paper, it’s worth it. I’ve tried the cheaper paper, which is good for test prints, but you need the high quality stuff for good prints.

5. DPI, dots per inch. Depending on your printer and your software you may be able to print up to 1200 dpi which is probably unnecessary for what you’re doing. For up to a 4 by 6 inch print you only need about 300 dpi. Most people cannot see the difference between a 300 dpi an a 600 dpi at 4 by 6 inches. For 5 by 7 or 8 by 10 you can go up to 600 dpi.

These steps will help you on your way to printing great digital photos at home. Remember though make sure that you have fun printing all those memories.

FYI Just so that you have a frame of reference, I’m a professional photographer and I have a six color ink jet that I paid less than $300 for and photo editing software that I paid less than $100. I print my 5 by 7 images for shows at 600 dpi.

If a new webcam technology from Microsoft get the go-ahead, then instant messaging could get a whole lot more interesting.

Currently under development at the Microsoft research labs in Cambridge, England, the new webcam, i2i consists of two lenses, which carefully follows an individuals movement. Using an exclusively developed algorithm to cleverly blend what each lens is seeing, resulting in the creation of an accurate stereo "cylopean" image.

All very technical, but for the 18.5 million people source Microsoft who regularly use webcams while they are using instant messengers, i2i means that it will appear as if users are looking into each others eyes.

Antonio Criminisi, lead researcher of Microsofts Machine Learning and Perception Group, said.

"We were able to come up with an algorithm that was able to take two images and capture a corresponding map in 3D. Using this powerful technology, we can now synthetically create an image as if the person is looking straight into your eyes."

According to Dr Criminisi, the biggest challenge for the backroom boys at Microsoft was in calculating how the visual brain works. In particular, how it sees and sorts out colors, shapes and distances.

"Essentially, what we have done is replace human eyes with cameras and the human brain with a computer."

The real magic behind this technology is the newly developed stereo algorithm, which makes it possible to accurately reconstruct a 3D, geometric image in real time and on a standard computer. Fundamentally, this is the same technology which was used to recreate the stunning 3D images of the Martian surface, which were beamed back by the NASA rover.

With the ability to generate realistic looking background images in order that users can pretend they are somewhere other than where they really are! Commenting, Dr Criminisi said.

"This is important for privacy, as I may not want you to see how untidy my bedroom is."

A feature likely to capture the teens market is that of Smart Icons. Instead of typing in the usual pictorial emotion e.g. : i2i can superimpose free floating, 3D ones which can then be instructed to float freely around a persons head or anywhere else for that matter.

While Dr Criminisi admits there are still issues to iron out before the project is passed on to Microsoft Development, he is pleased with what has been achieved in under two years. Dr Criminisis team is already experimenting with code which enables users to create their own wrap-around avatar, 3D face and then have it move as if it were their own.

DVD CD ROMs have become predominantly the most used CD drive for desktop and notebook computers. They are very reliable and now come as a standard in most computers. If you are looking for a laptop then make sure it has a DVD ROM, this will give you extra speed for normal Cds, and you will be able to watch your favourite DVDs while you travel.

I often sit up late watching DVDs on my laptop after a hard working day.

If you are interested in Desktop computers, then the DVD drive will enable you to watch your favourite DVDs on your monitor. I currently have a 21-inch monitor and a 5.1 computer surround kit. This brings DVDs to life and acts just like a home cinema system, however the quality is even better.

Most DVD ROMs will come in speeds ranging from 4 to 10 speed. This is more than adequate to watch the latest DVDs, play the latest games, and use and install the latest software. Normal CDs can only perform at a certain speed, and it is a lot lower than what the DVD ROM offers. I hope you have a better understanding of why DVD ROMs are now used more than a normal CD nowadays. It is basically all part of bringing a home entertainment system at the best quality closer to everyone.

Heres how to format a hard drive Legal Stuff: We are not responsible for any damages, lost data, or anything of the sort...

If you have a computer, you surely know what a hard drive is. If you dont have one, or simply dont know what a hard drive is, then this article will begin with a short description of the hard drive. Then we will cover formating a hard drive...

Step 1: What Is A Hard Disk Drive

A hard disk drive in computing is a type of storage device made up of hard disk platters, a spindle, read and write heads read and write arms, electrical motors, and integrated electronics contained inside an airtight enclosure.

Now you know what the hard drive is. Lets stick to the point and start with the information on the title of this article. How to format a hard disk drive....

Step 2...

First of all, you should have a reason if you really want to learn how to format a hard drive. But dont forget that formating a hard drive does NOT permanently delete your data!

Of course, when you format your hard drive you think that the data is really deleted, but that is not the case.

The fact is that the data you have "deleted" can be restored. Nonetheless, you should not experiment with formatting a hard drive because you never know what may happen. Of course, it also depends on the software you use, for example, there are such products that will permanently delete the data you want and then you can continue the process of how to format a hard drive.

Step 3...

In fact there is nothing so difficult in it. You first need to decide what operating system you intend to load after formating a hard drive.

It is best and easiest to use a boot disk for that Operating System, such as MS Dos6.2 or Windows95b or Windows98SE. You will need the proper Windows95/98 boot disk in order to load these operating systems on the computer, else it will reject loading due to the wrong Operating System on the computer.

Step 4...

Then you will have to insert your boot disk in the floppy drive and start the computer.

Once the system has completed booting and an A: prompt appears. You will need to type format C: /s and then press Enter. The function of this command is to tell the system to format your "C" drive and when it is finished to copy the system files to the drive.

The "/s" switches for "System". You can format a different drive this way by using a different drive letter.

Step 5...

After that you will see on the screen the following text: "WARNING, ALL DATA ON NON-REMOVABLE DISK DRIVE C: WILL BE LOST! Proceed with Format Y/N" and if you really want to continue, type [Y] and then press Enter.

Your screen should display the size of your drive and a countdown in percentage of formatting completed. Depending on your computers speed and the size of the drive it can take from a few minutes to over 15 minutes.

When it reaches 100% complete, you will see a new message: FORMAT COMPLETE. SYSTEM TRANSFERRED. This message is to indicate that the files required to boot your computer from the hard drive have been copied from the floppy to the hard drive.

The computer can now boot from the hard drive without a boot disk in the floppy drive.

The last message that will appear on your screen is the following: "Volume label 11 characters, ENTER for none" You can either press any key to continue, or simply to press Enter. And now, you can finally begin to load your Operating System.

Keep in mind that you can receive an error message, which says "insufficient memory to load system files". If you do receive such message, do not worry. It is caused by the lack of a memory manager loaded at boot and your PC can only access the first 1mg of ram memory.

You can handle this situation with two options. The first one is to omit the /s switch when formatting. You should do it by typing this: FORMAT C: and then press Enter. Then when the format is complete, manually add the system files to your hard drive by using this command: SYS C: and press Enter again.

The second solution is to load a memory manager in order to overcome this issue. If you dont have any you can easily download one from one of the million sites on the Internet.

Step 6...

You see, we have finally reached the end of How To Format A Hard Drive. and consequently – the end of this article. Now you surely know how to format a hard drive. But, once again, dont play with the commands if you are not serious about formating a hard drive.

Even if the data is restorable you may do something wrong to your computer. That is why, you should be careful! And now, good luck!

Its easy to be intimidated by all the laptop models on the market today. There are literally dozens and dozens in every price range.

The key to finding the right one for you is to step back and consider exactly how you plan to use your laptop. When you define what you need before you go shopping, buying the right machine becomes much easier.

Here are 5 basic factors to consider:

1. SIZE

In the world of mobile computing, size definitely matters. The size of a laptop affects two key areas: portability and display size.

If youre always on the go and will be using your computer only in short bursts, a so-called ultralight will save you some shoulder strain.

On the other hand, if youre going to spend hours in front of your laptop, a larger display may be in order.

Today, some laptop displays exceed 17 inches, rivaling the display size of many desktop systems. The down side is that these monsters can easily weigh three times as much as an ultralight.

2. HARD DRIVE

Speaking of size, what about the size of the hard drive One way to approach this issue is to ask yourself the following question:

Will this be my primary computer, or will it supplement my desktop system

If the former, you should look for a bigger hard drive - 60 GB or more.

If the latter, you may be able to make it with a 20-30 GB hard drive.

But even this isnt absolute.

If, for example, you plan to copy a huge MP3 library from your desktop system to your laptop to make your music library portable, youd be well advised to err on the side of too big.

3. MEMORY

In determining the right amount of system memory, or RAM, take a look at the ways in which you intend to use your laptop:

If your needs are somewhat mundane - email, spreadsheets, word processing, etc. - 256 MB of RAM should be plenty. This is a common configuration for many laptops, so it means you probably wont need to spend extra for more RAM.

On the flip side, if youre an aspiring mobile digital photographer or videographer, you should stuff your laptop with as much RAM as it can hold.

In fact, exactly how much RAM your laptop can hold may in part drive your purchase decision. Applications for editing and manipulating multimedia content are notorious resource hogs.

4. NETWORK CONNECTIONS

Thanks in no small part to the Internet, computing in the 21st century relies heavily on being connected:

Connected to the Internet, connected to a corporate network, connected to a wireless network, connected to a home network, connected to an online service.

Your life will be easier if you buy a laptop that includes built-in means to connect to them all.

5. PRICE

If youre considering a laptop, youre probably wondering how much money youll need to spend.

A few years ago, youd be hard-pressed to find one for under $2,000. Today, there are plenty of laptops to be had for under $1,000.

Whats more, most of the major manufacturers offer a variety of financing options.

Laptop prices have come down, to be sure. However, a laptop still represents a fairly major purchase for most people.

If you take the time to search for a laptop that meets your specific needs, you should get many years of use and enjoyment from this important investment.

If youre a bargain shopper looking to get the most bang for your buck, youll find no shortage of deals on the Internet.

And thats particularly true in the fast-changing world of laptop computers, where youll find three bargain sources right at your fingertips:

1. Clearance Sales

Just like many brick-and-mortar retail stores, many computer manufacturer websites have clearance sections. On these web pages, you can find great deals on last years leftovers.

These are all new products unless otherwise stated and carry their original warranties. The only difference is that the price has been reduced.

Of course the manufacturers arent the only ones with clearance merchandise.

Major electronics and office supply retailers also include clearance sections on their websites, where you may be able to find the laptop bargain of your dreams.

2. Refurbished Laptops

Factory refurbs represent another great bargain opportunity. It works something like this: Joe Blow buys a new laptop, but decides a week later he doesnt like the color. He takes it back to the store within the stores stated return period, so the store is stuck with it. Since they cant sell the laptop as new, the store sends it back to the manufacturer to be "refurbished." The factory inspects that laptop to make sure everything works right, and then ships it out to a retailer that deals in refurbs. The refurb retailer then sells it to you at a great discount off the original price.

Buying a refurb can literally save you hundreds.

3. Online Auctions

You can always logon to an auction website and find a great deal on a used laptop. However, beware!

Buying anything used carries with it some risk. Buying a used laptop carries more risk than most people should be willing to take.

When you buy a used laptop from a private party, you dont get any sort of warranty beyond DOA.

DOA stands for "dead on arrival", a common auction term that means the seller guarantees the item will work when it arrives at your house.

But what happens if your laptop dies two weeks after it arrives Youre out of luck, thats what.

There are enough bargains available on warrantied laptops that all but the most meager budgets should be able to avoid buying used.

Stick to clearance and refurb machines and youll save yourself hundreds on your next laptop computer.

If youre planning to purchase a laptop or notebook note that laptops and notebooks are the same thing, consider buying used or refurbished laptop. A refurbished laptop is a used laptop that has been rebuilt by a professional, and made to be like new again.

First, let us take a moment to consider your needs in a laptop. What do you plan to do with your laptop Do you your plans include the following: Surfing the internet Checking emails Instant messenger Writing papers Printing Papers Making spreadsheets Slide Presentations Playing Solitaire Downloading MP3s Listening to MP3s Burning to CDs Watching DVDs Digital camera photo Childrens games Keeping bank figures Small business use The lists goes on...

Most used laptops will easily complete all of the above mentioned tasks for you. Whats really great is that for most current applications on a refurbished laptop, you wont notice a performance difference compared to a brand new laptop.

How is that possible to not notice a difference between a brand new laptop and a refurbished one

Thats a good question. The fact is, most current software for your computer is not designed to need the high performance of a brand new laptop. Computer manufactures are moving so fast, that software makers simply do not keep up. Most current software will run on a computer 4 times slower than the fastest laptops made.

Most current software will run flawlessly on a computer 4 times slower than the fastest laptops made.

What does that mean for you It means that its not necessary to spend $1500 or more on a top of the line laptop. Depending on your needs from your laptop, you may be able to buy a laptop for as low as $250. A $250 laptop will perform all the necessary tasks for most people. However, if you are looking for a laptop that will burn CDs and watch DVD movies, expect to spend $400 - $750.

Dell says I can buy a brand new laptop for $699, why should I buy a used one

This is a very smart, and very much overlooked, marketing trick. Let me start by saying that I think Dell is the best computer manufacture on the market, and I endorse their products myself. However, try this yourself on any given day with any manufacture : Today I went to do www.dell.com and browsed new inspiron laptops The Dell line designed for home users. On the home page was an ad for a laptop "from" $699. This is after a $100 rebate, so make that price $799. I click the ad and attempt to purchase the item. I am offered to "Customize" or choose "Recommended Solutions". Customizing sounds great. Im the customer, and I should get what I want. After choosing "Customize", without selecting any upgrades at all, suddenly the price of the laptop is $1371. I dont like that, so I chose all of the lowest possible choices for all available features to achieve the lowest price. The lowest available configuration made the price $907. I dont want to give up, so I go back and choose "Recommended Solutions" because these configurations are pre-manufactured in quantity, and are therefore cheaper. Four options were offered at these prices: $949, $1249, $999, and $1319. Each one of these options was offered a $150 rebate keep in mind this is a mail-in rebate so it doesnt lower your price at checkout so respectively, if I were to purchase, then wait for my rebate, I could get a laptop for $799, $1099, $849, or $1169. Not one option was available to purchase this laptop at the advertised priced price of $699, even after a mail-in rebate! You will find the same scenario anywhere you go, no matter what manufacture.

No option was available to purchase a laptop for $699, even after a mail-in rebate!

They have to get you to buy from them somehow. All of the computer manufactures have been using this marketing technique as described above for years. Imagine if everyone knew about this and the money they could save on buying a refurbished laptop, without having to sacrifice any of their goals and needs from the computer. These manufactures would not be the same companies that they are today.

There are more reasons to consider a refurbished laptop.

Another aspect of buying a refurbished computer that should be considered is this: Most refurbished laptops available are not the "low end" home user based laptops. Examples of home user laptops are: Compaq Presario, Dell Inspiron, eMachines, Hewlett Packard Pavilion, Sony Vaio, and Toshiba Satellite. Refurbished laptops are almost always business model laptops that are off-lease from major corporations.

Business laptops have parts available even long after warranty expires.

Business laptops provide a better solution because they are the laptops provided by a company that are proven to work well. Examples of business laptops are: Compaq Armada, Dell Latitude, Hewlett Packard Compaq Mobile/Business Workstation, and Toshiba Tecra. Home user laptops, believe it or not, are usually testing grounds for new engineering of laptop equipment. Home user laptops are typically given shorter warranty, and are designed to last until that warranty expires. After the laptops warranty has expired, the newer "experimental" home user model available uses different parts. Since the older models are no longer under warranty, and they use "out of date" parts, the manufacture no longer stocks the parts. Therefore, when your home user laptop has an out of warranty problem which it will, the parts that are available to fix your laptop are very expensive, if they are available at all. This leaves the home user with the attitude to "throw away and buy new", which is exactly what the manufacture wants you to do.

Since business laptops use technology that is proven to work, their parts seldom change from model to model. Due to this fact as well as the fact that business laptops are leased to corporations, huge stock piles of parts are kept at the manufacture for extended warranties as well as out of warranty purchases. For example, you can still call Dell today to order parts for an out of warranty laptop that was manufactured in 1997 or 1998 for the same cost as laptops manufactured in 2002.

Business laptops are more expensive than home laptops as much as $3000, buy used and save a ton.

Business laptops, due to their stability, are far more expensive than home user laptops. Using the Dell example, the cheapest Dell business laptop Latitude, currently available is $2000. Many of the refurbished laptops being sold today for $250-$800 originally sold for $3000 or more. This means you can buy refurbished and save as much as 80% over buying new.

Purchase a refurbished laptop that will suit your needs and last for years, at a great savings.

Youve laid out good money for your laptop computer, but youre not done spending just yet.

There are a few more laptop accessories you may want to consider to make the package complete.

1: Laptop Case / Bag

As the newest member of the mobile computing force, youre required to take an oath of safe computing.

And that starts with investing in the most important of laptop accessories - a laptop bag. You cant very well go traipsing around the world with your laptop exposed to the elements.

When it comes to laptop bags, you can spend $25 for a small case made from less expensive materials on up to several hundred dollars for one made of top-grain cowhide.

However, in the end, the most important consideration is whether your case can hold your laptop, plus all the other goodies that go with it like the ones described here.

2: Software

Did your laptop come with software If so, did it come with the right software - the software you actually need to perform whatever tasks you need to perform

Dont just assume you have everything you need. Youll probably need to add some software, as well as go online to update the software that was included.

3: A Real USB Mouse

Trackpads and eraser nubs that fill an obvious need. However, given the option, most people would rather user a real mouse.

If you stop and think for a moment, youre likely to realize that many places where youll be computing actually are suitable for a real mouse.

So one of the most useful laptop accessories you can buy is a USB mouse, keep it in your bag, and use it whenever youre able.

4: A Cat5 Ethernet Cable

Your built-in Ethernet port wont do you much good if you get to your hotel room, discover an Ethernet connection, and dont have a cable. Some hotels provide them; others dont. Always come prepared with the right cable.

5: A Standard Telephone Cable

The same holds true for your modem connection. If you dont have a cable to get you from your computer to the phone jack, youre not going anywhere in cyberspace.

6: Disposable Cleansing Cloths

Over time, the display on your laptop is going to get dusty, or even smudgy. Youre playing Russian roulette with your laptop if you attempt to clean your display with paper towels and spray cleaners.

Instead, use disposable cleansing cloths. These essential laptop accessories are designed specifically to clean laptop displays. Always have a stash on hand.

7: USB Drive

A USB drive is a storage device about the size of your thumb that plugs directly into a USB port.

Capacity-wise, theyre relatively small - usually well under 100 MB. However, theyre very useful for moving files quickly and easily from one computer to another, e.g., moving a PowerPoint presentation from your laptop to your business associates laptop.

A USB drive also makes a great temporary backup medium for the really important files you create on the road.

8: Blank CD-R Discs

Youve just finished your big sales presentation. Someone from the audience approaches you afterward and asks for a copy of the presentation.

Youll make a better impression if you:

a ask the person for their email address and tell them youll email the presentation later

b ask for their physical address and tell them youll mail a CD later

c burn them a CD of the presentation on the spot.

In case you didnt figure it out, the answer is c. Always be prepared with these inexpensive laptop accessories.

9: Stereo Headset

Its great to be able to watch DVD movies no matter where you are. Imagine watching your favorite flick at 30,000 feet.

Theres just one problem.

The family in the row behind you has absolutely no interest in hearing the dialog from Pulp Fiction.

Do yourself and everyone around you a favor. When youre watching movies or listening to music in public, use your headphones.

10: Security Device

Laptop security devices come in many shapes and sizes.

For example, most laptops include a security dock that allows you to attach your laptop to some immovable object via cable, much like youd lock up your bicycle outside the grocery store.

A laptop computer certainly provides you with an unprecedented level of freedom and mobility away from the office. However there are a few extras you might want to bring along on your laptop travels:

Extra 1: portable printer

If you travel a lot, you never know when you might need to commit one of your digital documents to paper.

Sure, you can probably find a Kinkos, or even the business center at your hotel, but the experienced business traveler knows youre much better off when youre not at someone elses mercy.

Extra 2: USB hub

If you need to connect to several external devices simultaneously, the one or two USB ports on your laptop may or may not be sufficient. If not, keep an inexpensive four- port USB hub in your laptop case.

Extra 3: PC card token ring adapter

Ethernet is the industry standard for computer networking, however back in the 1970s IBM introduced a competing technology called Token Ring.

While Token Ring has all but faded from the mainstream, some hardcore IBMers still use it.

If youre going to be working in such an environment, youll need a PC Card to connect to the network.

Extra 4: Foreign power kit

If you travel abroad, youre bound to run into a wide variety of power schemes - power schemes that arent compatible with your laptop.

When youre away from the homeland, youll need some sort of adapter/converter if you want to plug into a local wall outlet.

These are relatively inexpensive and can be easily found online.

Your worst nightmare just became a horrifying reality. You keep hearing that little voice in your head mockingly shout “you should have backed that stuff up” The voice keeps echoing throughout your head as you perform a quick inventory all of the important information that you just lost…..your client database, a years worth of e-mail, your entire inventory database, even your family photos. Even worse, you’ve got a deposition in two-weeks and key information needed to help win the case were also lost. You quickly call a service technician and have them come over to check the computer out, only to hear the worst news of all….your data has been lost. When a hard drive crashes, it’s too late to worry about what you “should have done.”

Today data recovery is a multi-million dollar industry. The number of data recovery firms out there seems to exceed the number of fast food restaurants for the entire planet. These companies specialize in helping their clients retrieve data on anything from hard drives to flash-roms. In the following report, we will discuss what data recovery really is; the different types, the costs, and what you can realistically expect when it comes to getting your data recovered.

What To Do In The Event Of Data Loss

Around 44% of all data loss is caused by hardware failure. It’s important to make sure that you immediately shut your system down if you suspect that hard drive has crashed. Don’t even try to go through the shutdown procedure, just pull the plug from the wall. Do not try to run off the shelf data recovery software or drive utilities. Many times these applications will assume the drive is functioning properly and will increase the risk of permanent data loss.

Types Of Hard Drive Failure

When we discuss data recovery in this report, we will primarily focus on issues surrounding hard drive failures; since these types of failures are most common. There are really two primary forms of failure in a hard drive, logical and physical. Logical failures are usually a result of file-system corruption. This can occur due to a virus, accidental deletion of key files or registry components, and in some cases even electro-static discharge. In most cases where a logical failure has occurred, the drive is still recognized by the system BIOS, but it will not boot. In most cases, your data should still be intact on the drive, even though it may appear to be inaccessible.

If the system BIOS does not detect the presence of the hard drive, then chances are a physical failure has occurred. Physical failures can result from a wide variety of causes. There are really two sub-categories for physical hard drive failures; mechanical and electronic. Mechanical failures usually result from a failure of the spindle motor. Spindle motor failure can result from excessive heat due to a bearing failure. The increased heat resulting from the bearing failure will expand the drive shaft and therefore seize the spindle motor. Suddenly, your drive will become inoperative. Occasionally, you will get a warning that something bad is about to happen. You may hear a loud whining, a grinding noise, even high-pitched screeches. If anything like this starts to occur, BACK UP YOUR DATA IMMEDIATELY.

Another physical issue that sometimes rears its ugly head is an electronic failure. If you look at a hard drive you will notice a circuit board on the bottom. This board is basically the brains of the drive, and it is where the computer interfaces to the hard drive. An electrical failure can occur unexpectedly at any time. Even brand new hard drives are not totally immune to having electrical failures. Sometimes it’s just a faulty component, sometimes it’s improper installation i.e. electro-static discharge, grounding out the board, damaging circuitry during installation. It’s important to also keep your system clean and well ventilated, since excessive heat can damage the electrical components on the drive. If you have a system that is in a somewhat contained area, you may look at adding an additional 80mm fan to cool the internal components of the system, especially the hard drive. No other component of a computer works as much as the hard drive, and therefore it is vitally important not to overlook it when cooling issues arise.

How Is My Data Recovered

One of the most often asked questions that customers ask is, “how do you get my data back” Well, it’s really not black magic or rocket science. It’s just a matter of having the right tools and the knowledge necessary to know what to do, much like a surgeon performing heart by-pass surgery. Many prominent data recovery facilities have a large array of hardware, software and tools for recovering data.

Generally speaking when a hard drive is received by a data recovery firm, the first thing they do is evaluate it, and determine what recovery solution will be necessary. If the drive failure is a logical issue as mentioned earlier, then a scan of the drive will be performed to try and repair the file system corruption. Sometimes a partition can be repaired and the drive restored to the status that it was before the failure. If this is not possible, then a very low-level scan will be performed that essentially searches every sector of the hard drive for files. Once the files are located, they can then be copied to the media of choice, i.e. a CD-ROM, DVD-ROM or another hard drive. Logical recoveries can take up an enormous amount of time, especially if the drive is on the verge of physical failure. It’s not uncommon to allow for one day of scanning and a day for recovering the found files.

If the drive has suffered a physical failure, then the recovery procedure is quite a bit more challenging. As mentioned above, there are really two sub-categories of physical failure; mechanical and electronic. An important element in recovering data from a physical failure is having the necessary parts to get the drive functioning again. Unfortunately with hard drives if you have a 20GB Maxtor Hard Drive for example, then you will need another identical 20GB Maxtor Hard Drive for salvaging parts. In cases where the electronic circuit board has failed on the hard drive, then you have to have the exact same circuit board on hand in order to retrieve the necessary circuit components for replacement. Many times you cannot even exchange circuit board for circuit board. These repairs generally require soldering skills and a thorough knowledge of electronics to be successfully completed. You will most likely hear “Class100 Clean Room” thrown around a lot when talking to data recovery professionals. Simply stated, a Class100 Clean Room maintains exceptional air purity, and contains less than 100 airborne particles larger than 0.5 microns in each cubic foot of air. This is vital in protecting sensitive internal components of hard drives. Anytime a hard drive is having an invasive procedure performed on it, a Class100 clean room or better is needed.

The time frame for recovery is generally 5-10 business days for physical issues and 2-4 days for logical issues. Sometimes if components are not readily available, then it may take weeks to complete the recovery. Some firms offer expedite service and you definitely pay for this added attention.

What About Data Recovery Software

This is one area where you really do get what you pay for. Try to stay away from software in the $20-$60 range, since these utilities are generally very limited in what they can do. Also make sure that you NEVER and just to emphasize, NEVER EVER get data recovery software that writes anything at all to the damaged disk. You run the risk of overwriting data that may otherwise have been recoverable, but will be lost forever. If you are fairly computer savvy, then there are a few good data recovery software solutions available.

What To Look For When Shopping For Data Recovery

There’s an old saying, “you get what you pay for.” In most cases this is true. However, just because a company with a fancy website quotes you $3,500 for data recovery, does not mean that they are any better than a company that quotes you $1,500. Also, try to stay away from companies that want to charge $50-$300 for evaluating your drive. There has been a movement in the data recovery industry over the last couple of years to offer a number of free services. Most reputable data recovery companies will evaluate standard IDE drives free of charge; so don’t let the word “free” this or “free” that stop you. The data recovery market is quickly becoming saturated, and a company does not necessarily cheapen itself or lack expertise by offering free evaluations.

You will find as you shop around for data recovery that prices vary greatly. You will get quotes that range from $300 to $5,000 for standard hard drive recoveries. It’s not uncommon to literally get quotes that have at least a $1,500 high/low spread. We shopped one prominent data recovery company where we gave them specific indicators of a physical hard drive failure. We were eventually quoted a price range of $600 to $2,900 for the recovery. Many times this is a bait and switch type tactic. They get you to send in the drive with the low-end $600 price, then they let you know it’s going to cost $2,100 for the recovery. You end up being well under the $2,900 high-end price, but well over what other reputable companies would charge. Since most customers won’t go through the pain of having the drive sent back, only to have to send it out to another company, these bait and switch companies end up making huge profits off of unsuspecting customers.

Try to find a company that will give you an up front cost for either a logical or physical recovery. Most companies will be able to tell you within a couple hundred dollars the cost of a recovery. However, don’t misunderstand a company that gives you a price for two different procedures. For example, some companies will give you a price if the failure is logical and a price if the problem ends up being physical. We called one firm and were told that if the drive had a logical failure the price would be $400 and if it ended up being a physical issue the price would be $1,600. This is not a high/low spread as mentioned in the earlier example, this is simply quoting a price for two different types of recoveries.

On average you can expect to pay anywhere from $400 to $600 for logical recoveries, and $1,200 to $2,000 for physical recoveries on standard IDE hard drives. If you have RAID drives, SCSI, etc. depending on the configuration prices can be as high as $15,000. Remember, backup backup backup backup backup!!

Can My Data Be Recovered

In most cases the answer to this question is yes. On average, the success rate for data recovery professionals is about 75-85%. However, there are times when the data is just lost, either due to extensive damage to the platter or unavailability of replacement parts.

How Do I Get Started

If you have a hard drive that has crashed, the most important thing you can do is contact a data recovery professional immediately. Make sure you aren’t being charged an evaluation fee if you have a standard IDE hard drive. Most companies only charge evaluation fees for complex RAID and network server drives.

It is important to do your homework, call and talk with the companies. When you find one that you feel comfortable with, give them a chance. Your hardest job, may be finding data recovery firms that actually have someone available to answer the phones. Ask questions and be sure to have the following information available: Size of the drive Operating system i.e. Windows 98, Windows XP, etc. Situation of failure what happened just before the drive stopped working Is the drive recognized by the computer or not

Good luck in getting your data recovered, and make sure you always backup your important information on a daily basis.

Perhaps the biggest mistake people make when building their computers is to underestimate the importance of the hard disk drive HDD. In our modern society, bigger is synonymous with better, so when you go to buy a hard drive you look at how "big" it is, its data capacity. But is that all you should be considering when buying your hard drive

Like every other component of your computer, the HDD is far too complex a system to describe in any sort of detail here, but hopefully by the end of this article you will know what to look for when you go to buy your new hard drive.

There are 4 primary aspects to look at in a hard drive in order of importance: Rotational frequency and average seek time Buffer size Internal/external transfer rates Capacity

Rotational frequency has become a large selling point 5400/7200/10000/15000RPM recently, so you shouldnt have too much difficulty finding out what the rotational frequency of your HDD is when you go to buy it. Now of course the faster it spins, the faster it can read from the disk there are other advantages also, but be aware that the faster it spins, the more wear is put on the drive, and the more likely it is to encounter errors and malfunctions later in life. Hard drives are pretty much the only systems within your computer that have moving parts CD-ROM, floppy disk drives, and fans also have moving parts, but theyre all cheap and if they break you wont lose all the data youve accumulated over the course of owning your computer, be sure to back up your data regularly!. If you know anything about physics or engineering, then you know that moving parts produce friction and wear, and a faster spinning platter the part that holds the data and spins means more friction, and therefore more wear on your drive. Of course the faster it spins the faster it can read data from the platter. So what can you do well again you backup your data as much as possible and you get the fastest spinning drive money can buy which is 7200RPM for ATA devices the sort you are buying and 15000RPM for SCSI and some Serial ATA devices you might get Serial ATA, that depends on your motherboard. So look for a "7200RPM" label on the drive youre thinking of getting, its important!

The "buffer" Im referring to is the transfer buffer that temporarily stores data to read from or write to the hard drive. The reason for this is that the bus data channel between the hard drive and the motherboard can only handle so much information at a time, and it takes a long time for the data to be found and retrieved from a platter random seek time, so it takes a big chunk of the requested data and stores it in a very fast data buffer to be sent at the buss convenience. So with a larger buffer you can queue more data for transfer over the bus without having to keep sending requests to slowly find more data from the platters. Some newer drives come with as much as 8MB of buffer capacity, but it is more common to see 2 or 4MB. Usually a drive with a large amount will use that as a selling point and print it on the box/website, otherwise you can assume it has a 2/4MB buffer. My advice is to find one with as much as you can afford.

Now for the transfer rates youre going to need to do some searching, the best way to find these numbers is to go to the manufacturers website and look at specification sheet for the model youre looking to buy actually this is the best way to get all the information Ive talked about so far. One thing to look out for is that you may read something that says 133MB/s or ATA/133 or SATA150 or 150MB/s, and these are not the numbers you are looking for, those numbers describe the bus connecting the hard drive to the motherboard, and are theoretical peak numbers, which tell us virtually nothing. Also, if you are buying a Maxtor, dont bother looking up actual transfer rates, as Maxtor is apparently afraid to release such information. Not to say Maxtors are bad drives, actually Maxtor has risen to the top in terms of technical support and they are much more willing to replace broken drives than some other companies, which is important since some ridiculously large amount something like 10 or 15% of hard drives are either dead on arrival or die within the first few weeks of use. As with the last two points, when looking at transfer speeds if you can find them always try to pick the one with the highest numbers you can afford.

Notice that the first three of the 4 major aspects were all speed related That was done intentionally to give you a sense of the importance of speed in the hard drive, because they are very very slow creatures, and for your gaming experience you dont need an enormous hard drive so much as a fast one. To increase speed substantially more you can set up a RAID, which is a network of hard drives which in RAID0 mode share portions of the same data, such that accessing data takes 1/n time n = number of hard drives attached compared to 1 hard drive. To do this you really need a hardware RAID chipset, which are commonly included on higher-end mainboards.

Finally, capacity is an unnecessary nicety. The smallest hard drives you can buy today that are still within those higher speed classes are all about 30GB, which is more than enough for your games. But since games are not everything, and if you happen to be an iTunes member or like to download anime then you will really want some extra space. So I would recommend getting something between 60 and 120GB, any more and youre going to be paying through your teeth, any less and you might be looking to buy a supplementary hard drive in a couple years. And, oh yeah, 300GB hard drives from Maxtor are out, but they are comparatively slow, so I wouldnt recommend getting one for gaming, I like to stick to single platter drives 40-100GB usually, as they produce less heat and are less likely to break down on me.

That is really all you need to know in order to make a good choice when upgrading your hard drive or buying one for a new computer. Of course there are many other resources on the web if you would like more detail on the inner working of hard drives.For further information please visit http://www.computer-gaming-system.com

So you’ve finally decided it’s time for a change. No matter what advice you follow that old work horse of a desktop computer you have has outlived its usefulness with slow loading applications and a continuous rise in operation noise.

Searching for that Perfect Computer can be about as much fun as purchasing a new car and about as frustrating also when sorting through the various brands while trying to decide which “bells and whistles” best fit your needs. Besides all that trying to return something that is so large can be both inconvenient and very difficult to do.

So making the right decision the

FIRST time is the wise path of choice.

For starters you’ll need to decide what you want to do with your computer. Are you into the video game scene or are you someone who likes to just surf the internet and occasionally do some book keeping with simple word processing software

If you’re into video games you’re going to want a machine that can handle the high level of graphics and superior sound quality.

On the other hand if you’re not into all that high adrenalin stuff can probably get by with a less expensive system. Although, if you want to stay on the safe side I would recommend going with something more “high-end” so you don’t have to spend another large chunk of change to upgrade the system you just bought.

There are two basic routes you can take when purchasing a new computer.

1 Purchase a “Brand Name” Computer

2 Purchase a “Clone” Computer

A “BRAND-NAME” computer is one that is manufactured by a company that is recognizable by name.

Some Advantages/Disadvantages of “Brand-Name” computers include:

Advantages-

Customer Support- If you are experiencing problems with your computer you will have the option to contact a representative of the company that you purchased the PC from to get help in solving your problem.

Customer support is probably the best reason to buy a brand-name computer.

Warranty- Having a warranty is always nice since it acts as a type of security blanket for you.

In case a part on your computer should fail you should be able to get the item fixed at no charge just as long as the warranty has not expired.

Read and understand a company’s warranty policy BEFORE you purchase a computer from them.

This way you’ll have a good understanding of the procedures to follow in case a problem should arise.

Pre-installed Software- Many companies will include software packages that are all set up and ready to go for you on your computer.

Although, a disadvantage of buying a brand-name computer with software pre-installed is that you usually end up with more than fits your needs and usually just results with the wasting of space on your storage device.

Additional Support- Most brand-name computer companies are also able to provide you with web sites that may provide you with current software updates, user manuals, or basic troubleshooting help.

Disadvantages-

The use of Proprietary parts- the term Proprietary refers to products that are unique to an individual company and that company only.

So if a part was to malfunction on your computer after warranty and you needed to replace it you could not just go to your local computer store and purchase any old part even if it was intended for the same function as the item that failed.

You would be forced to buy the exact same item that came out of the computer or else the computer would more than likely cease to function correctly.

Having to buy proprietary parts usually involves the need to place an order which means you’ll have to wait for the part to arrive or you’ll have to send your computer into the company or an authorized dealer of that company for repairs.

People with a home based business would probably not be too happy with that situation at all.

Integrated/On-board parts- In the computer world when you hear the word integrated or on-board it means that a particular part such as the modem or sound port where you plug in your speakers, is built-in or part of the computer main board Also known as the Motherboard.

This means that if any of these items should fail, you can’t just remove them from the computer and replace them with a new part. They are usually soldered directly to the main board and are stuck there.

Although, some computers do provide a way to disable a malfunctioning device which will allow you to install your own store bought device to take the place of the broken part.

From a computer technicians point of view this is not always easy to do.

It just depends on what brand of computer you currently have. Meaning some are easier to work on than others.

A “CLONE” computer is a clone or a copy of its brand-name counterpart with the exception that instead of company specific or proprietary parts, the items used to make a clone computer are from several different companies instead of only one.

Let’s say that if you were to go to a local company that builds “clone” computers, and you tell them what you need, chances are they don’t use parts that are specific to only that type of computer like the brand-name computer companies do.

This is a good thing because it means that they will probably use components that are interchangeable with many different brands and are easy to come by if needed.

Some Advantages/Disadvantages of “Clone” computers include:

Advantages-

Cost- compared to brand-name computers the clone will generally be easier on your pocket book when purchasing one with similar features as its brand-name counterpart.

This is most likely due to the money that is saved by not offering the high-end customer service. Although, that may not be the only reason for the lower prices.

Easily Accessible Replacement Parts- Since the clone computer was built with parts that are not any one company specific, you can buy parts for the clone computer that can be used even if the brand is different from the one that was in the computer when you originally bought it.

Note: Before you buy any parts, it is necessary to make sure that the replacement parts are compatible with your particular computers system requirements.

Either consult the manual that should have came with your computer or get help from a knowledgeable friend or repair person.

Disadvantages-

Warranties- Unless you purchase a service plan you will typically not have as an attractive warranty as you would with a brand-name computer company.

Whatever you do just make sure you understand how long the warranty is for and as to what kind of repairs the warranty covers before you make the purchase.

Customer Support- With brand-name computer companies you are usually provided with a 24-hour toll free number that you can call if you have questions or concerns with your computer.

Clone computers are more than likely not going to have a 24-hour help service, but rather you will be forced to only be able to call during regular business hours.

Also, it is more than likely that there will not be any one website that you can go to in order to find out information concerning troubleshooting questions you may have.

For service it may be necessary to take the computer back to the store that you bought it at or you may have to do some research on the individual parts that went into the computer and visit the manufacturer’s website for troubleshooting tips.

Finally, if all else fails you can certainly take what you have learned from this article and being that you know what you need now, but don’t know where to go and get that “Perfect Computer”, the best resource at your disposal are the very men and woman that work at your local electronics shop.

It is their duty to help you get hold of that “Perfect Computer” that best fits your needs. All you need to do is tell them what you plan on using that computer for and they should be more than happy to help you from there.

The Power Supply converts your regular household current into low DC voltage used by the computer. When this component fails,there is simply no activity going on wih your computer.Remember to do the easy troubleshooting first.Inspect the Power Supply for any damage.Double-Check all connections.

Learning how to check your power supply and how to replace it when needed can be a life saver if youre a computer buff or in business with the trusted PC.Dont take for granted the simple pleasure of turning on your PC and everything works just fine.

We turned on one of our computers recently and in about one hour,it just re-booted itself.And it continued doing so about 10 times a day until we found out the power supply was the culprit.Things to look for when your power supply is going bad or just dies on you are the following.

NO POWER TO THE COMPUTER

Here you must first check the wall outlet for power by connecting another device such as a radio or lamp to be sure power is present.If the computer is connected through a surge protector,check it as well.

If the wall out has power,check the power cable going to the PC to see if AC voltage is making its way to the system unit.Do this with the use of a multimeter.

If there is power,you will have to open the PC and check for power from the power supply to the motherboard.

When using a multimeter to check voltage,be sure you have a good ground for the black lead of the multimeter.

RE-BOOTING PROBLEMS

One main problem you may face with an ailing Power Supply is that it may re-boot the computer without any warning.All information is lost and it seems as though this happens at the worst possible time.

Booting errors when the computer first starts up is another indicator of this component going on the blink.

POWER DISTRIBUTION PROBLEMS

When the power supply begins to fail,you may receive power at one device and not another.For example,the Hard Drive may receive power but the CDROM Drive has nothing at all.

Another headache with would cause re-booting is the intermittent power going to the drives or the motherboard itself.Follow the steps below to check your power supply should you experience some of the above problems.

CHECKING THE POWER SUPPLY

If the wall outlet,and the power cord are good,make sure the connection at the motherboard is secure.Then you may have to face the fact that the power supply itself is bad.If you have a Multimeter you can test the power supply output before purchasing a new one.Simply follow these steps.

Turn off the PC,but do not unplug it,open the system unit. Set the multimeter to read DC volts in the next range higher than 12 volts.Locate a power connector similair to the hard drive,or cdrom drive connector that is unused and turn on the PC.

You can also unplug a drive connector and use it as well.Turn on the PC and insert the BLACK probe into the power connector on one of the BLACK wires.Touch the RED probe to the YELLOW wire on the power connector.

The multimeter reading should be +12 volts Now touch the RED probe to the RED wire and the reading should be +5 volts.If no readings or different readings occured,youll have to replace the power supply.If the readings were correct,you should check the P8 or P9 connectors at the motherboard. These connectors may also be named P4 and P5.To check these connectors,perform the following...

Insert the BLACK probe into P8 at one of the BLACK wires. Insert the RED probe into the P8 connector at the RED wire. The reading on the multimeter should be +5 volts

Check the power going to the Motherboard connections by inserting the RED probe into P8 at the YELLOW wire and you should get +12 volts.Leave the BLACK wire touching the black wire at the P8 connector.Check the BLUE wire and the reading should be a -12 volts.

Now move the BLACK probe to the BLACK wire on the P9 connector.Test the WHITE wire by inserting the RED probe and the reading should be -5 volts.Check the RED wires on the P9 connector and you should get +5 volts on each red wire.You wont get exactly 5 or 12 volts but the readings will be very close, such as 5.02 volts.

If the Power Supply is a couple of volts off,in either direction,such as when the RED wire should be reading -5 volts but it reads -8 volts,or if there are no readings,replace the power supply.

DO NOT remove the power supply from the system unit case when performing these tests.DO NOT perform these tests if you do not feel comfortable.Be sure to remove any and all electrical static build-up from your clothes and body BEFORE touching any parts inside the system unit.And NEVER open the power supply case for any reason,since high voltage may be present.

What is a Refurbished Computer

Refurbished Computers. Remanufactured Computers. Reconditioned Computers. Essentially, all of these terms refer to the same thing. But what does refurbished really mean A refurbished computer is one that is sent back to the manufacturer for a variety of reasons, refitted with different parts as necessary, and then tested and approved for resale by the manufacturer. Yes, this could mean that a computer was returned because it didn’t work properly. But, this is not always the case. There is a excellent chance that the problem was nothing more than a cosmetic defect, such as a small ding on the monitor. Or it could be that a custumer recieved the wrong model, but had already opened the box.

Most importantly, refurbished doesn’t mean that you’re buying a computer with a defect or something else wrong with it. All computers go through the same testing and approval process refurbished and new alike.

Refurbished Computers are not Old Computers.

Buying refurbished doesn’t mean you’re stuck with an outdated machine. While computers are forever becoming faster and able to hold more data on larger hard drives, the basics of the computer are still the same. The technology used is typically less than a year old, so you can get processing power and memory specifications that are almost the equivalent of brand new models, but at a much cheaper cost. If you just want an inexpensive computer to do e-mail, surf the Internet, balance your checkbook, play a few games, and do some word processing, you might want to invest in a refurbished model. Most are still upgradeable in case you want to add more memory, a larger hard drive, or even a faster processor later on.

Who Should buy Refurbished Computers

Many people new to technology are unsure what there needs are. It often makes sense for them to purchase a refurbished computer. I recently did this for my grandmother. She enjoys geneology and has many boxes and books full of information about our family. The internet is a great tool for researching your ancestory and sharing the fascinating stories that you find. My grandmother had very limited experince with computers, but I purchased a Compaq for her for Christmas. She loves it, and it has allowed her to store much of her information electronically and to share that information with family all over the United States.

Small home offices can also benifit from purchasing remanufactured computers. Many companies cannot afford a huge investement into hardware. By purchasing quality used equipment these businesses can take advantage of the benifits of technology without breaking the bank.

One of the most incredible inventions I’ve ever come across is the web cam and its process of video conferencing. This is just so futuristic I can’t believe they really exist and are readily available to anyone with the Internet, speakers, and the right software. I’m not absolutely sure but doesn’t this spell the end of telephones Now we can have conversations with people on the other side of the world, and see their face moving as we hear them speaking live.

Picture this: You’re an Antarctic explorer on a solo journey in the middle of the ice and snow on your way to the South Pole. The only living creatures around are the slippery penguins sliding around having fun. You’re in your special tent keeping safe from the intense wind from the blizzard outside. As you boil up water on your portable stove you flip open your laptop with battery recharger, broadband Internet, and in-built speakers and connect with your family back in Russia. You can see their smiles as you hear them speak. What a magical connection!

Another great aspect of video conferencing is the fact that you can communicate with whole groups of people at once either through networking a group of computers or by form of broadcast. This is a huge step forward for both companies and for schools. I’ve heard corporations have saved a lot of money and time, and students are enjoying learning this way much more than from a textbook. Informed people can talk to classes and help them learn, where otherwise they wouldn’t be able to because of time and distance restrictions. This is also a bonus for children who have different learning styles. E.G. The more visual types who understand better when they can see what they’re working with.

Feasibly, a surgeon in Japan could watch an operation in Australia and even ask the doctor in progress questions about procedures. It’s obvious that video conferencing will both help humans evolve further through the sharing of knowledge as well as keep loved ones more connected when they are far from home.

A lot of people who are either fascinated or obsessed with sex will also tell you about the benefits of this technology for their voyeuristic purposes, but I’m not going to go there. Science Fiction has once again turned to reality, and I hope we can truly make the most of this invention created by humans who wish to make society a better place.

A dedicated server is a single computer on a web-hosting network that is leased or rented, and dedicated to just one customer. A service provider monitors the computer’s hardware, network connectivity, and routing equipment, while the customer generally controls and maintains the server software. Dedicated servers are most often used by those who’ve outgrown typical hosting accounts and now require massive amounts of data space and bandwidth, those with mission critical web sites, web hosting companies, or those who have special needs. Dedicated servers are housed in data centers, where service providers can monitor them close-up and have hands-on access to them.

The primary advantage of using a dedicated server over a typical shared hosting account is the sheer amount of resources and control available to you, the customer. In many cases, the client is at liberty to install whatever software they desire, giving them greater flexibility and administrative options. Dedicated server clients do not share resources, as those with shared hosting plans do; but rather, are at liberty to use all the resources available to them.

Managed Servers vs. Unmanaged Servers

There are two types of dedicated servers available today: Managed Dedicated Servers and Unmanaged Dedicated Servers.

An Unmanaged Dedicated Server leaves nearly all the management duties of running a server in the purchaser’s control. The customer in this case, updates software on their own, applies necessary patches, performs kernel compiles and operating system restores, installs software, and monitors security. With this type of dedicated server, the consumer is solely responsible for day-to-day operations and maintenance. The service provider, in turn, monitors the network, repairs hardware problems, and troubleshoots connectivity issues. Additionally, some service providers offer partial management of services, such as network monitoring, software upgrades and other services, but leave the general upkeep of the server in the hands of the client. An unmanaged dedicated server is best for someone with server management experience.

A Managed Dedicated Server is generally more proactively monitored and maintained on the part of the service provider. When renting or leasing a managed server, the service provider or host carries out the responsibility of software updates and patches, putting security measures in place, performing hardware replacements, and also monitoring the network and its connection for trouble. In other words, when utilizing a managed dedicated server, the host provider will perform both hardware and software operations. A managed dedication server solution works well for the customer with limited server management experience or limited time in being able to perform the duties necessary to keep a server running and online.

Technical Aspects In Choosing A Server

When choosing a dedicated server, there are several things to consider: Operating System, Hardware options, Space and bandwidth.

The Operating System of a server is similar to that on your own personal computer; once installed, the operating system enables one to perform tasks more simply. There are a bevy of server operating systems available today including Linux-based and Windows-based software. The operating system you choose should be directly relational to what operations your server will be performing, which types of software you’ll need to install and also, what you’re more comfortable with.

Hardware Options are also something to consider when choosing a dedicated server. You’ll need to pick a processor that’s up to the task, the amount of memory you wish installed, firewall options, and the size of the hard drive.

A certain amount of bandwidth is generally included when renting or leasing a dedicated server. Once you ascertained how much bandwidth you will require, you can adjust that limit with your service provider. The space you’ll be given is generally directly relational to the size of your hard drive. Some hosts also give clients the choice of uplink port speed usually 10Mbps/100Mbps.

It has happened! Computer games have started to control my life on and off the screen. No complicated games like Age of Empires, just the simple one of Tetris. You know the one, where different shaped and colored bricks fall out of the sky and you have to arrange them in nice lines at the bottom Hopefully with the end result of all colors matching in straight lines so that they can be removed and point gained.

Crazy really, it first happened many years ago when I had this stupid bet that I could get more points than the next guy. What that really means is that, "I am going to be up all night playing this game and will be totally incapable of staying awake in the office tomorrow, unless of course I play the game in the office as well". That’s what computer games do to us. We become machines where food and sleep are secondary items to all else. Just keep on playing.............till you drop.

I managed to get through that episode with only a slight increase in my weight and a damaged back from not having moved anything else except my two fingers for a sustained period of time. The latest episode though has created havoc with my life in more ways than one and I am getting seriously worried about it.

I had been playing that game in the evening for around three hours and had then gone to bed early for a dreamless and normal sleep. All okay and expected you say Well, the sleep was but when I drove to the office the next day things started to happen that rapidly woke me up to the danger that I was in. There I was in my blue car approaching the traffic lights when all of a sudden I swerved into the other lane thus ending up stopped neatly behind this other blue car. Behind me, confused and irritated drivers with green and red cars tooted their horns angrily wandering what this maniac was doing. But I I was happy in that I had managed to get the colors arranged and all I needed was another blue car and then we could have a full line................oh, no, what is happening to me I sat there for a while shivering as it dawned on me that I had entered the game itself, it had taken me over.........I was a brick!

Yeah, and that was not all. I found myself one afternoon staring inanely at a house wall and following the line of bricks along trying to sort out in my mind which pattern was best and which was not. And at my desk I found that I had arranged all files and papers in a neat pattern according to color and size having totally disregarded any format associated with the importance of in-going, outgoing, urgency, etc. Extremely worrying to say the least!

I have withdrawn from playing Tetris and other games of that sort hoping that I will stop having these off the screen episodes in real life. In the hope that I can return to a normal existence without having off-the-screen battles. Do other people suffer from this or is it just me

The other game that I played to have a break from Tetris was "Prairie Dog". One of those annoying games where you have a choice of guns and dogs keep on appearing on the screen. Aim and fire being the next step. Bang, Bang, Bang, another dog bites the dust. Yes, I know, pathetic really, but great fun. Volume up full, there I would be furiously firing at any movement, reloading and starting again and the dogs would make a strangled sound as I hit them. But once again I one day realized that all was not well with me, as I used to sit on my balcony and take imaginary potshots at cars as they appeared on the road. Or in a busy street I would say "bang, bang" and pretend that I had cleared a path for myself through the crowds.

I played that other game Age of Empires many times to. Love that game as it takes s kill and thought as well as two fingers and rapid movement and I became extremely proficient at it as time went by. My computer often struggled to cope with the size of my army and the enemies that I faced. I would sit there for hours on end, maneuvering, shifting, attacking and withdrawing till the sun started to come up on the horizon. It would be then that I would force myself away and climb into bed only to resurface two hours later, make a large urn of coffee and re-attack with a vengeance. Although this game never caused me to start charging at other cars on the highways or lobbing screwed up notes at others in the office it did cause me to take a good look at myself. What would happen if suddenly I started to do this sort of thing in real life If I started to make deals with my neighbors to attack next door offices or ping elastic bands at the mail delivery boy I’ve stopped playing games now and have become a serious and boring "been there, done that and cured myself" type of person. I do have long and empty hours where I feel the urge to take up where I left off and I get extremely jealous when others talk about games or I see others playing them but I resist. I think it must be like smoking where one never loses the urge to light up and take a draw – just the one! No, No, I cannot! I now sit there and lecture others on the dangers of playing games and that they should stop before it is too late. And they They just nod politely and then disappear to talk amongst themselves............."must be and ex-player", whisper, whisper, whisper.
