What are the main components of the computer system?

We all know that computers are complex devices, electronic components and components made of amalgam machines. Which computer components are needed to run the computer? Modern PCs can still work fully without a Bluetooth or floppy drive. Below is a list of computer components that computer systems can not do.

* Motherboard

The motherboard is a very basic unit in any computer system. This is a computer component that all other internal computer components are connected to. Connects all other major components of the computer system. As a result, motherboards are sometimes referred to as the "heart" of a computer system.


Central processing unit or CPU is computer component responsible for running computer programs and applications. If you do not have a computer on your computer, you will not be able to perform any task – you can not launch an operating system, listen to music, videos, and games, and you can not make any text editing. The CPU must have the computer running.


Random Access Memory or RAM is another vital computer component. This is a storage device where your computer temporarily stores data and information that you can randomly run while running programs and applications. With the CPU, RAM determines the computer's speed. Computers with large RAM and mediocre CPUs can actually run faster than a computer that has a high CPU, but low RAM.


Instead of RAM, the hard disk drive or hard drive stores computer files and data over a long period of time. Even without power, the hard drive keeps the files stored in it. The hard disk can store important system files, such as the operating system, program files, and other data. It can also be used for MP3 and video storage. If your computer is emptied of RAM, temporarily use the hard disk as a virtual memory bank.

* Video Card

The video card allows the computer to display images on a computer monitor. It helps speed up displaying images on the screen and contributes to clearer and more detailed images. PC gamers and multimedia software users have a high-end dedicated graphics card that helps simplify graphic intensive programs.


The power supply to the power supply or the power supply supplies all computer components. It transforms high voltages from an AC outlet to smaller internal voltage voltages that are safe for internal computer components. Without the power supply, the computer and its components will not turn on.

Your computer may be advantageous from an optical drive to read and play CDs and DVDs, network card and router to connect to the Internet, and peripheral devices such as printers and scanners. However, the motherboard, processor, RAM, HDD, video card, and PSU are components of the computer system.
