What's Inside A Computer ?
Motherboard: This is the backbone of your system. It is the main board that all the other components plug in to. When it is time to upgrade, find out which processors it will support. Low price computers are sometimes designed with motherboards that have other peripherals permanently set, limiting the system's ability to upgrade in the future. Make sure you can upgrade your system if needed.
Processor: A processor is the brain of the computer that will affect how fast your system will perform, however other factors play a large role in performance. Do not solely compare computers based on processor and price! Processor options are available for your selection and and a model is available that will work nicely for most users.
Ram Memory: Ram is where your work gets done. The more space you have the more work you can do. The amount of Ram should be based on the type of applications you will be running and the operating system you use; 64 megs should be minimum for Windows; 128 megs or more for advanced applications. The type of Ram you have will also affect your computer's performance.
CD-ROM: All new computers should come equipped with at least a 54x CD-ROM
Modem: A modem is the device that allows your computer to communicate with other computers over the phone lines, (The Internet) 56k or v.90 modems are now standard. There are other faster means of connecting such as DSL and Cable Modems, however those are a bit higher in price.
Hard Drive: The hard drive is the storage area for your computer. Its capacity will determine how much software can be loaded into your computer. Twenty to forty Gigabyte is entry level by today’s standard. Twice the capacity should not be twice the price.
Sound Card: For most users, a 16bit sound card is sufficient, however if audio quality is a high priority, get a Sound Blaster card with a wave-table. Keep in mind that pre-packaged speakers are often inferior. Better speakers make a big difference. Unless your system is for all work and no play it should have a sound card.
Video Card: The video card is a circuit board that transforms your data into a viewable image on the monitor. There is a large range in performance and and a large range in the price. High end video cards are required for the latest gaming software. Thirty-two megs of Ram on the video card should be standard for today’s systems but do not only consider the amount of Ram.
There are several other considerations such as monitors, keyboards, and printers, scanners, etc., where your budget & needs will determine your purchases.
Computers are advancing very rapidly in today's market. It’s important that the computer you purchase today is upgradeable for the future.
