The first step to building your new computer is knowing which parts to replace. Below is a useful guide to help you understand the vital hardware in computers that make up your system.
· Motherboard
The motherboard is the heart of your computer system. It is the most important computer hardware component and is situated inside the tower case. The motherboard is a large rectangular part made up of dozens of circuits connecting all of the sub-components in the tower, such as the CPU (central processing unit), disc drives such as the CD, DVD and HDD and additional expansion slots such as USB.
· Power supply
The power supply unit is a lengthy cable that plugs into the back of the tower case and an external power socket in the wall. This is what enables your computer to be switched on. The power supply of a computer is especially unique as it is designed to convert alternating current (AC) from electricity to low-voltage current (DC) in order to power the sensitive internal components of your computer.
· Graphics card or video card
The graphics card, or video card as it is also known as, of your computer is what allows you to see output images on your computer monitor. Graphics cards are available in many different versions ranging from intermediate for basic everyday computer usage to advanced graphics cards for intense computer gaming purposes. Some graphics cards offer additional features such as 3-D image rendering, MPEG-2 and MPEG-4 decoding, FireWire, light pen, TV output or multiple monitor connecting abilities.
· Internal storage
This is the component of computer hardware that stores all your data and information, making it easily accessible for later use. Your computer’s internal storage consists of a HDD (hard disc drive) and a solid-state driver (similar to a HDD but not removable). Though one cannot remove the solid-state drive, you can upgrade your computer’s internal memory by purchasing a larger-capacity HDD.
· Sound card
Your computer’s sound card allows you to play music, movies or video games with sound if a pair of speakers or earphones is plugged in. Sound cards also accept input from a microphone to your computer but may require you to install additional software in order to use the microphone. Most computer hardware components such as sound cards are built in to the motherboard but additional sound cards can be purchased for enhanced sound quality.
