A+ An Overview
The A+ certification demonstrates competency as a computer technician. Officially,
CompTIA A+ certification is a vendor neutral certification, that covers numerous
technologies and operating systems from such vendors as Microsoft, Apple Inc.,
Novell and some of the Linux variations. The A+ certification exam was developed in 1993.
There have been four versions of the A+ exam, the 1993, 2003, 2006, and 2009 objectives,
which are broken down into two separate exams. The 2003 objectives contained the A+ Core
Hardware Exam and the A+ Core Operating System Technologies Exam, and were retired on June 30, 2007.
The 2006 objectives require that a candidate successfully pass the A+ Essentials and one
elective: IT technician, remote support technician, or depot technician. The 2009 certification
requires passing two exams: Essentials and Practical Application.
The A+ exam is intended for information technology professionals who have the equivalent of 500
hours of hands on experience. The exams are computer based and composed of multiple choice questions,
of which there may be more than one correct answer. Over 800,000 people have earned the A+ credential
worldwide, to date.
Topics of the Essentials/Core examination include IRQs, direct memory access, and
practical computer repair, including the installation and repair of hard drives, modems, network cards,
CPUs, power supplies, PDAs, and printers. The focus of the exam is not theory, but practice.
Sometimes graphics are used in exam questions. Topics included in the Operating Systems Exam
include memory management, configuration files, and historical operating environments rather
than newer, cutting edge technologies.
