Dear Friend‚ The first personal computers were home-built by electronics hobbyists. When Apple‚ IBM and others began selling ready-made systems to "normal" folk‚ most buyers never considered opening the case‚ even to look‚ much less make changes. That was roughly 25 years ago - one human generation‚ but more than a dozen generations for computers. By the second decade of the personal computer age‚ computer stores were selling hard drives‚ memory upgrades‚ sound and video cards and other components to an increasingly large segment of the home computer market who wanted to make their PC "more" than what the manufacturer sold them. Today‚ such parts can be found in any office supply or general merchandise store - even some supermarkets and drug stores. But even with this wide and easy availability‚ even with prices that continue to drop as capabilities continue to rise‚ many people are convinced you have to be an electronics wizard to open that case. "Understanding PC Hardware" will help dispel that myth‚ explaining in simple language‚ just what each part is‚ what it does and how it can be replaced.
