A+ certification is possibly the most popular way of breaking into the computer tech business, as it demonstrates basic competency regarding computer hardware and software. Offered by CompTIA, the certification involves taking two tests: the A+ Essentials exam and a choice of one of three elective exams: IT Technician, Remote Support Technician, and Depot Technician. The knowledge base required involves understanding how to take apart a computer and put it back together, how to build a computer from its basic components, knowledge of the purpose and function of component parts such as the motherboard, CPU, display devices, power supply, and cooling system, among others.

In addition, on the software end, the A+ certificate seeker is required to know all about modern operating systems. While CompTIA is vendor-neutral, it emphasizes knowledge of the Windows operating system, because A+ certification is designed to produce computer technicians who can make a living, and Windows holds the lion’s share of the OS market. However, the certificate seeker is still required to have a basic understanding of Apple and Unix-like operating systems. He or she is required to understand the boot process as well as the basic framework of multiple operating systems, so that he or she can provide adequate support to customers needing assistance.

Regarding Network+ certification, the basic premise is the same as that for A+ certification, except it is required for anyone who wants to be an IT network technician. The certification shows that the successful Network+ candidate is able to maintain, configure, install, troubleshoot, test and manage all sorts of network infrastructures, has an understanding of modern networking technologies, basic design principles, and grasps modern wiring standards. In addition, the Network+ certificate seeker benefits from having the A+ certification since Network+ requires the same technical skills as a foundation. Networks contain multiple computers, as well as the nexuses between them, so it’s far trickier to troubleshoot than just a single computer.

The specifics involved in the Network+ test involve knowledge of common networking protocols, both wired and wireless, as well as an understanding of all the hardware involved in creating a network. He or she must know how to set up a fast and secure computer network utilizing firewalls, routers, and switches, and ensure that it is free of viruses and malware. The certificate seeker must be familiar with all the tools of the trade, as software-based and immaterial as packet sniffers and port scanners or as gritty and hardware-based as cable-strippers and temperature monitors. He or she must be able to diagnose problems and have adequate knowledge to come up with a solution.

Any job with a major technology company involving technical expertise will require A+ certification, and if you’re looking to be a network or systems administrator, Network+ is increasingly necessary for your career. Many major corporations, such as Microsoft, Cisco, Novell, and HP, include the CompTIA Network+ and A+ certification in their mandatory training requirements.
