Taking the mystery out of today's PC, this self-paced, troubleshooting exercise book empowers students with a hands-on, working knowledge of the personal computer's internal operation—covering all major hardware aspects, including the motherboard, floppy and hard drives, CD-ROMs, display adapters, sound cards, and modems. A valuable resource for students of all computer skill levels, it employs a fictitious computer specialist Joe Tekk© (as a handy troubleshooting guide), and rounds out the learning experience with thorough and easy-to-follow discussions on networking hardware and a wide range of other important microcomputer-related topics.
