\ From Barnes & NobleThe Barnes & Noble Review\ If you’re a computer technician, or want to be one, A+ certification is rapidly becoming a requirement, not an option. The two A+ exams have been revised, so an old book may not cut the mustard anymore. Jean Andrews’s 1,000-page study guide most assuredly will. \ Andrews covers every exam objective on both the A+ hardware and operating system exams: the boot process, power supplies, motherboards, processors, memory, disks, I/O, multimedia, and Windows 9x/Me through XP. It’s all here, from the latest peripherals, buses, and memory standards to Wi-Fi networking.\ This book’s more visual than many A+ guides. Its hundreds of photos and diagrams won’t just make learning easier: They’ll make this a handy reference for your day-to-day work.\ There’s also a good deal of practical coverage you won’t find in run-of-the-mill A+ books. For example: a step-by-step walkthrough of building a PC from the ground up. Six appendices cover everything from error messages to hexadecimal numbering and memory addressing. There’s even a quick Linux primer, enough to help you cope if a Red Hat box walks in the door.\ The accompanying CD-ROM contains MeasureUp software with more than 200 super-realistic sample questions for each A+ exam. You can practice in “Study Mode” (work at your own pace, see correct answers immediately) or Certification Mode (a timed test that simulates the real thing). There’s even a Custom Mode, which lets you test yourself on the topics you’re most worried about. Oh, and to help pay for the book, a 20 percent discount coupon on the exam itself. Tough to beat that. Bill Camarda\ Bill Camarda is a consultant, writer, and web/multimedia content developer.
