Widescreen vs. Standard—If you plan to watch a lot of movies on your computer, then widescreen is the automatic choice. But even if you do not plan to make a theater of your PC, widescreen monitors serve a good purpose: you can have two programs open at the same time, have them share the screen and still view enough of both programs to easily work on both. That is just not truly possible on a standard size monitor, no matter how big it is, because it is the widescreen ratio that allows one to view both programs so easily.

Size—the choice between 17”, 19” and 20” is really a matter of personal preference, based on space considerations and, more importantly, eye sight issues. If you have any issues with your vision, the larger the monitor the easier it will be to use. Going larger than 20” is definitely a user preference.

Contrast Ratio—this is simply a measurement of the monitor’s ability to display true black, instead of dark gray. It is listed as 500:1 or 800:1, for example, which are the most common ratios. For most purposes, 500 or 800:1 contrast ratios are just fine. If you are a gamer or a perfectionist about how pictures, graphics and movies will look on your monitor, go for a higher ratio. A 2000:1 contrast ratio is about as high, and as good, as it gets.

Refresh Rate—this is a measurement of how fast your monitor refreshes its picture. It is listed as 8ms, for example, where ms equals milliseconds. 8ms is the most common rating and is acceptable for most users. The lower the number, the faster the refresh rate, and I have seen monitors rated at 2ms refresh rate. Only a true, hard core gamer would notice the difference.

Many systems come with the video card integrated on the Motherboard of the computer. If you use your computer for basic documents and spreadsheets, web browsing, email and games such as Solitaire and Free Cell, this is a good solution for you. It is also the least expensive, which makes it that much nicer. But if you envision using your computer to play video intensive games or work with and edit digital photos, you may want to consider buying a system with a separate video card. ATI Radeon and nVidia Geforce are two of the more common Video Card upgrades available in the marketplace today

That is what Integrated Audio, or a Sound Card, and speakers will provide. As with video, most systems come with Integrated Audio on the Motherboard. This is usually all that most users require. But if you want a truly awesome sound experience, consider adding a Sound Card such as SoundBlaster cards available from Creative Labs. Of course, you must have speakers to hear the sound produced by the Integrated Audio or Sound Card. The better the speaker system, the better the sound, but most $20-$30 speaker systems will give you all the sound you need. Unless you are looking for a “concert hall surround sound” experience, there is no need to look for higher quality speakers, and the higher cost.

Most new systems come with 4 to 6 ports which generally are more than enough. But if you feel you want extra USB ports, our recommendation is that you simply buy a USB Hub from your nearest Best Buy, Office Depot, CompUSA, etc.

Developed by Apple for the Mac computers, it is not a necessary option if your system does not offer it. But many new PC’s today are offering Firewire connection.

Created to cater to exact needs, these machines can reflect your desires as a computer user, allowing you to do more specialized tasks than a name brand machine. Whatever you want to accomplish with your computer, MCT can help you achieve that goal with a specially built, custom PC.

There are two main companies providing processors to manufacturers: Intel and AMD. Both firms offer a low-end chip, or CPU, and a high-end chip. The less expensive chips from Intel are the Celeron Processors and from AMD come the Sempron Processors. The high-end AMD chips are the Athlon 64x2 Processors; the high-end Intel chips are the Intel Core 2 Duo Processors. The question becomes, of course, which do you need? If all you do is run simple applications such as Word, Excel and other office applications, the low-end chips will provide all the power you need. But in today’s world computer users are working with photos, music, surfing the Internet, writing email, burning CD’s and DVD’s and working on that letter to the company President all at the same time. If that describes you, then you will be better served by the high-end chips.

This software is offered by our friends out in Redmond, WA, Microsoft Corporation. Operating systems have evolved from the basic DOS, to the Windows 3.x versions, to Windows 95, 98 and ME, as well as Windows 2000 and, of course, Windows XP. The current offering from our friends in Redmond is Windows Vista, and it comes in several different flavors, er versions.

What it means to you is how fast your computer can run multiple programs at the same time. The more memory, the faster you computer handles the appetites of all those hungry programs. For Windows XP machines you should have a minimum of 512MB (MB stands for megabytes, just a way of measuring memory). For Windows Vista machines you should have a minimum of 1GB (gigabyte) of memory; 2GB is recommended.

You can have a small closet or you can have a nice, big walk-in closet. The bigger the closet, the more you can store and the easier it is to find stuff. The same applies to the hard drive in your computer: the more space you have, the easier it is to store things and find, or access, those things when you need them. Space on a hard drive is measured in gigabytes; with standard sizes ranging from 80GB upwards to 250GB. All your software (including Windows), files, data, music, pictures, etc. comprise those “things” stored on your hard drive that you need to find. So how much space do you need? If you are simply working with email and documents, the smaller sizes of 80 to 120GB would do just fine. If you plan to have a lot of digital photos or music stored on your computer, go with the larger options, although 250GB would suffice for most users. Only the hard-core collectors of digital photos and music, or gamers, would need the larger hard drives. One last word about hard drives: you will see reference to Serial ATA (SATA) and IDE hard drives. Do not be confused by this, it just defines the way the hard drives connect to the PC. The older PC’s use IDE hard drives; the newer PC’s use SATA hard drives.

This means you can play music CD’s or look at pictures saved (burned, recorded, written) to a CD, save files to a CD and watch a DVD movie, all using the same drive. Another commonly available drive is the DVD+/-RW drive. That’s a lot of letters and this is what they mean: this drive will play (read) both CD’s and DVD’s as well as burn information to both CD’s and DVD’s. The cost of these drives has dropped dramatically in the past year. If you have an enormous amount of material on your computer to back up, or if you envision saving movies, for example, to your PC and then burning them to a DVD, you will definitely want the DVD+/-RW drive. Otherwise, simply choose the standard combo drive described earlier. One last note on optical drives: some systems offer dual drives, that is two separate drives in the same computer. This can be a good option because it allows you to use one drive as a player and the other drive as a burner when you are copying discs; or to listen to a music CD on one drive while using the other drive to look at pictures saved on the disk; or anything you can imagine doing with two drives at the same time.
