Computer Repair Fundamentals: Preparing for the A+ Essentials Exam covers the A+ Essentials exam and each chapter includes these features:

• Methods and Modes --best practices
• True Life Technician--troubleshooting
• Things that can get you killed or fired--safety and professionalism 

The A+ certification is the most popular certification program in the world, certifying more than 500,000 individuals since its inception in 1998. These exams certify your knowledge of basic computer hardware and operating systems. This certification is extremely popular because it is essential to anybody who requires a baseline set of skills or competencies: high school students, technicians in your company's IT support group, even the delivery truck driver who wants to explore a better career opportunity.  Revised in 2006, the new exam format makes it mandatory for every candidate to pass the A+ essentials exam first and then pick from three other exams depending upon their career path.
