This concise guide offers study material for three CompTIA certification exams: the A+ exam for computer service technicians, the Network + exam for networking professionals, and the Security + exam for security technicians. As with other O'Reilly Nutshell books for certification exams, this book follows a unique style and approach. The idea is to cover as much exam study material as possible in minimum number of pages. All the important information on hardware, protocols and services is boiled down and condensed, and none of the exam objectives are missed. Smaller paragraphs, detailed tables and all-important screen shots are some of the features that make this book a valuable study companion.
