Created in 1982 by a quintet of computer dealerships, CompTIA is a non-profit trade association that provides professional certifications for the IT industry. A+ and Network+ are just two of the many certifications that CompTIA offers. Despite offering A+ certification since as early as 1993, ones for Network+ were not offered until 1999. While it is not required, the professionals at CompTIA recommend that in addition to the A+ certification, those applying to take the Network+ exam should have at least 9 months of networking experience.
Part of that experience requires knowing the parts of a computer. Surgeons don’t operate on their patients without studying human anatomy first, which is why it’s important for IT professionals to know the anatomy of their computer. Those seeking an A+ or Network+ certification must become familiar with the parts of a computer before they can move forward with their studies. Regardless of their area of expertise, here are 6 essential elements they must master.
The motherboard is like the lungs, as it breathes life into the computer. Everything else – for example the memory, battery backup, and CPU fan connector – all attach to it. If the motherboard goes down, the computer will not operate.
The CPU, or central processing unit, is akin to the brain of the computer. It carries the instructions of a program out to all other parts of the computer, whether those instructions are arithmetical, logical, or related to input/output operations.
The PSU, or power supply unit, is to the computer what the heart is to the human body. But while the heart pumps blood, the PSU pumps electricity. Depending on the type of PSU, it converts various forms of current to DC (direct current) power which is required for the computer to operate.
RAM stands for random-access memory, and it is a type of data storage. Like nerves that run through the human body, RAM stores information in case the power source is removed. The two primary forms of RAM are static (called SRAM) which uses a flip-flop state to stores a bit of data or dynamic (called DRAM) which uses transistors to store data.
The monitor is to the computer what the eyes are to the human body. It is a form of electronic visual aide that displays the results of what is going on inside your computer. Modern computer monitors are built with eco-friendly technology such as automatically going into standby mode after a predetermined period of inactivity.
Keyboard & Mouse
The keyboard and the mouse are types of hardware that help navigate across the visual displayed through the monitor. These types of hardware could plug directly into the computer via a USB or other designated port, while other styles are wireless and connect through a Bluetooth setting.
Even if you’ve never done any computer programming, it’s possible to obtain either an A+ or Network+ certificate. A variety of training centers, both of the online and brick-and-mortar variety, offers classes that use the most up-to-date coursework and technology to teach the essentials.
