Query: "Repair" is really "Replace"

The authors offer a nice description of the main components within a PC, and how these fit together to give you a working machine. Necessarily, they use technical jargon. But the level of discussion does not assume any previous technical background on your part.Also, several chapters are devoted to the vital subject of how to hook your PC into a network, via wired or wireless means. In either case, hubs and switches are explained. While these are not part of a PC, nowadays, a lot of the value of a PC is when it is connected to the Internet.Note that "Repair" in the title is really a misnomer. An important point made by the authors. If a part of a PC breaks, it is rarely repaired. The complexity is often beyond most customer's ability to do so, or that of a local computer shop, for that matter. Plus, the low price of the part often does not make it economic anyway.
