A+ certification is a testing program sponsored by the Computing Technology Industry Association(CompTIA) that certifies the competency of service technicians in the computer industry. The exams cover a broad range of hardware and software technologies, but are not related to any vendor-specific products. The program is backed by over 50 major computer hardware and software manufacturers, vendors, distributors, resellers and publications. Over 50,000 people have taken the A+ certification exams over the past 2 years, and CompTIA says the rate of those taking the exams is increasing rapidly. There are more hands-on, computer-related jobs than ever before, and job candidates are eager to get an edge on the competition by becoming certified. The Training Guide series is designed to offer all the information needed to prepare for the exams. Training Guides offer solid objective-based content, along with sample questions and exercises so readers learn the information in depth.
