Computer Parts and Computer Components

A computer is a multipart machine made from a mixture of electronic parts. Some components are very vital to ensure that the computer runs properly. There are some parts that the computer system cannot do without.

CPU (Central Processing Unit)

The CPU is the component that helps in the running of all computer applications and programs. You cannot perform major tasks such as booting an operating system (OS), playing videos, music or games or even doing any word processing without the CPU. Therefore a computer must have a CPU.

Motherboard

This is the part where other internal components are attached. It attaches all the internal parts of the system together. In some cases it can be said to be the heart of the system since it links all the major parts of the computer system.

HDD (Hard Disk Drive)

The main function of a hard disk is to store all the computer files or data for a long duration of time. It stores information even when there is no power. It can save program files, operating system or any other data that may be important to the user including videos or mp3s. The hard disk can be used as a temporary storage facility incase the computer is out of RAM.

RAM (Random Access Memory)

A RAM is a temporary storage facility for all information or files wile a computer is running a program or an application. Coupled with CPU, a RAM dictates the speed of the computer. The larger the RAM, the faster the speed despite having an ordinary CPU.

Video Card

Video card helps the computer to put on view all images on the screen of the computer (monitor). It speeds up the display of images on the screen and gives understandable and detailed images.

PSU (Power Supply Unit)

PSU ensures that all computer components are supplied with power. It converts high voltage power from an AC source to lower voltage which is safe for a computer. Without the PSU a computer cannot operate.
