This is the most comprehensive and practical learning and preparation guide for CompTIA's brand-new 2012 A+ exam. It combines the extraordinary knowledge of Scott Mueller's all-time best-selling PC repair book with comprehensive A+-specific guidance and practice. Three world-class PC hardware experts don't just show readers what they need to pass their exams: they show exactly how to apply their new knowledge in the real world. Every chapter takes a "ground-up" approach, beginning with the essentials and gradually building to larger, more complex concepts. Informative illustrations, photos and screen captures help encourage readers to follow along, building knowledge and confidence one step at a time. A handy "Objectives Index" show where each objective is covered in the book, helping readers make sure they study everything they need to know. Coverage includes: technician essentials, basic PC anatomy, motherboards, processors, BIOS, power supplies, cooling, RAM, I/O, video, customized PCs, multimedia devices, notebooks, mobile devices, printers, storage, Windows, networking, troubleshooting, operational procedures, communication methods, and more. Rich with learning and exam preparation features, this book includes an extensive collection of hands-on lab exercises, as well as up-to-the-minute test prep advice. Its CD-ROM enables at-home practice through sample questions presented by an advanced electronic test engine, additional lab exercises, and study notes.
