Prior to attending this class I thought I knew a lot about computers. What Ive learned is that all I really knew was "buzz" words: megahertz, gigabyte, ram, megabyte, etc. I also assumed bigger was better, and there "may" be some truth to that statement. However, it is equally true that bigger is not always necessary. I needed to purchase a computer that would satisfy all the needs and wants of the family. I needed a system that could run accounting software, my wife needed the ability to run graphic programs and the children needed educational software.

In addition to having a system with sufficient power to handle these tasks, I wanted the ability to expand the system at a later date, if necessary. Finally, I needed a sufficient warranty. After listening to the advice of friends and sales people, I was no better off than when I started. So I decided to go out on faith and buy what I thought was the best deal for my money.

I researched Compaq, Dell, Gateway and some no frills machines. The no frills systems were immediately ruled out; the price was right, the warranty was not. In some instances the warranty was ok, but I was not sure if I would ever see the person who built the system again. I purchased a Gateway select 600 for $ 2273. 00.

The system had: 600 MHz Athlon chip, 128 MB ram, 20. 0 GB hard drive, CD-RW, DVD, ZIP, 16 MB video, 17 " Color monitor (15. 9 viewable), HP scanner and Epson 740 stylus color printer (ink jet). All things considering I dont think I did bad, but I now realize that all that hardware was not necessary. I could have forgone the ZIP drive, my main purpose for it purchase was storage, which I now realize that the CD-RW could have done the same job. Not to mention that the CD-RW can hold up to 650 MB, as opposed to the 100 MB on the ZIP. I could have also forgone the DVD, the CD-RW is sufficient. I figured that maybe one day I would watch movies on the system.

Not purchasing these two devices I would have saved approximately $ 300. 00. If I were buying a system today, I would consider the following prior to purchase: Memory: Main memory, Primary storage or Random Access Memory (RAM), is the place where computers store information for immediate access. RAM is measured in millions of bytes or Megabytes, (MB). Most systems tend to come standard with 32 - 64 MB, and while still sufficient, I would pay the extra money for 128 MB. With video graphics and digital music becoming more popular, I feel the extra memory would be beneficial. I would also ensure that this memory is not shared with the video system, as this would decrease the memory available at all times.

Systems generally have 8 MB for video, with the advancements in graphics and my specific need to run graphic programs, I would spend the extra $ 30 -$ 60 to increase the memory to 16 - 32 MB. Processor Speed: Computers process calculations in Megahertz (MHz); one MHz is one million calculations per second. The processor itself, "CPU" or "Chip" controls and manipulates data to produce information. The rate at which these functions occur, depends on the speed of the computers processor. To be honest for everyday home use it is almost impossible to tell the difference between the processors: Celeron chips, and Pentiums II & III. There has been a lot of hype centered around this feature of the computer.

I have an old 133 MHz that runs most programs as fast as my 600 MHz Athlon. However, I think that 500 MHz is sufficient for home and small business use and if you have ample memory it does not matter whether you have a Pentium III, Celeron or Athlon chip. The speed will become more noticeable for those who utilize superior graphics programs, such as AutoCAD. Monitor: There are two basic kinds of computer monitors: CRT (cathode-ray tube) monitors and LCD (liquid crystal display) monitors. CRT is the technology used in television sets, and it is by far the most widely used technology for computer monitors as well. LCD technology, which is also called or "flat-panel display, " is most often found in notebook computers, but it is becoming more popular in desktop monitors.

Some differences between the two are as follows: Analog signal, compatible with most VGA graphics cards Better scaling to different screen resolutions Excellent color quality, gamma quality, and contrast Digital or analog signal; graphics card with a digital port required for digital models Thin and lightweight, fitting easily in any work environment Less than half the power consumption of CRT monitors Superior focus and screen brightness Resolution is a measurement of the number of pixels (horizontally and vertically) used to form an image on the computer screen. The more pixels, the sharper the image. However, it takes a monitor longer to display the extra pixels in a higher resolution screen, so at higher resolutions the "refresh rate" of the screen image slows down. To avoid eyestrain monitor size should be at least 17, with a dot pitch of at least 28 mm and a refresh rate of 75 or better.

Always try out the monitors before purchasing, make sure the picture is clear, crisp and not strenuous to the eyes. Video/Graphics Adapter: The most expensive cards are geared towards power "gamers" and offer the highest level of 3 D acceleration as their main feature. While other cards geared towards the budget PC market utilizes a more broad entertainment appeal, providing moderate 3 D acceleration as well as DVD and MPEG video decoding, and the occasional extra feature such as TV output. When considering a new sound card one should consider: bus type, memory size, fill rate; and video decoding.

Bus: Path data travels between devices. The PCI bus connects the PCI expansion card slots to the memory and the chipset on the motherboard. Data can travel at a fast rate along the PCI bus, up to 132 MB per second. However, there is an even faster data bus that is designed specifically for graphics cards, the AGP bus.

There are three types of AGP: AGP 1 X, AGP 2 X, and AGP 4 X. AGP 1 X, is twice as fast as PCI, with a transfer rate of 264 MB/sec. APG 2 X, is four times as fast as PCI; and with AGP 4 X, data travels up to 1056 MB/sec or eight times faster than PCI. Memory Size: A video card with more memory can store textures that are larger and more detailed. It can also reach higher resolutions in both 2 D and 3 D and display a sharper images and more colors. 32 MB is becoming the standard for most graphics cards, and, if needed cards with higher memory can be purchased... Fill Rate: Measures how many 3 D pixels a graphics card can draw on the screen every second and is measured in Mega pixels (Mpixels -- one million pixels) or Megatexels (Mtexels).

For every pixel, there can be several textures; "a texel", which is simply a texture applied to a pixel. Multiple textures are used to create 3 D effects such as reflective surfaces, transparent objects, and so forth. Graphic cards that have a high fill rate in both Mpixels and Mtexels perform well. Video Decoding: If you have a DVD-ROM drive and wish to play DVD movies on your computer screen.

Your computer needs to be able to decode the video data on the DVD disc, and that can be done either with a software program or a special hardware-decoding chip. Audio System: Although there is no official sound...
