Computer Hardware

Computer Hardware is a device that consists of various hardware components that work together to perform various functions. In this article, we will get to know 13 examples of commonly use computer hardware and what each of these components does.

CPU (Central Processing Unit)

The CPU is the brain of the computer which is responsible for carrying out instructions and data processing tasks. The CPU controls and coordinates the activities of the entire computer system.

RAM (Random Access Memory)

RAM is temporary memory use by computers to store data and instructions that are being actively processe. The greater the RAM capacity, the more data that can be processe simultaneously.

Hard Drives

A hard drive is a permanent storage device use to store data, operating system files and application programs. Hard drives have a large capacity and can store data for a long time.


The motherboard is the main circuit board where all the hardware components are connecte. The motherboard connects the CPU, RAM, graphics card, and other hardware to communicate and work together.

GPU (Graphics Processing Unit)

Is the component responsible for processing and generating graphics on a computer. GPU is very important in running graphics applications and games that require intensive graphics processing.

Power Supply

Power supply is a device that provides electrical power for all computer hardware components. The power supply converts electrical power from the power source into the power needed by other components.


Are output devices that display computer-generated information and graphics. Monitors allow users to view and interact with computer systems.


A keyboard is an input device use to enter text, commands and symbols into a computer system. The keyboard has keys consisting of letters, numbers and special characters.


The mouse is an input device use to move the cursor on the screen and select objects or icons. The mouse makes it easier for the user to interact with the computer’s user interface.


A printer is an output device that is use to print documents or images from a computer onto print media, such as paper. Printers can print in various formats and qualities.


Are input devices use to convert physical documents into digital files that can be store on a computer. Scanners are useful for importing text or images into a computer system.


A sound card is a device that allows a computer to produce sound. The sound card converts digital audio signals into sound that can be heard through speakers or headphones.

CD/DVD Drives

A CD/DVD drive is a device that reads and writes data on a CD or DVD. The CD/DVD drive is used for installing software, storing data, or playing optical media.


computer hardware is an important component in running a computer system. With an understanding of the functions of the CPU, RAM, hard drive, motherboard, GPU, power supply, monitor, keyboard, mouse, printer, scanner, sound card, and CD/DVD drive, you can understand how these components work together.

To perform a variety of computational tasks. Selecting and integrating the right hardware is key to building an efficient computer system that meets your needs.
