Get at least 64 megabytes, and 96 or 128 megabytes if possible. This is a dedicated memory bank that the processor uses to speed up its operations. It's a must. On a Pentium II or AMD chip, it should be 512 kilobytes. Hard disk Try for at least a six-gigabyte size, but you can settle for four gigabytes if your budget is tight.
Internet Make sure the PC is well set up for the Internet.
Almost all now have at least a 56K phone modem and built-in Web browsers with offers of Internet access. If you plan to use a cable modem, try to buy a PC with a built-in Ethernet networking connection, because cable modems typically use such hookups. Video system Don't be confused by all the video terminology. Just look for at least four megabytes of video memory, which is usually separate from the PC's main memory. You'll want more if you're a gamer.
