Components Of Computer / Various parts of the computer, if we talk about the computer, the image of the monitor is formed first in our mind, but in reality, there are many other necessary components in the computer besides the monitor, without which the monitor is also there. Experimentation is impossible.
As you also know that computers are made up of many components and parts, basically there are three types of computers: Analog computer, Digital computer, Hybrid computer. Out of which we will learn about digital computers. If we mainly talk about components, then there are three types of computers:-
- Input Unit
- Output Unit
- CPU (Central Processing Unit)
Today in this article we will learn about the components of the computer. What are the components, what is their functionality, how does it work? So without delay, let’s understand in detail…

These are Main Computer Components
1. Input Device
Input devices are those devices with the help of which we can access any command or instructions to the brain of the computer i.e. CPU (central processing unit), only after that all the processing takes place. If seen, the input devices between us and the computer. It is a medium to communicate.
Any question or data arising in our brain is fed into the computer only through the input device.
“The device which feeds any data or command to the computer is called input device”
There are many types of input devices:-
- keyboard
- mouse
- light pen
- touch screen
- digital camera
- joystick
- trackball
- scanner
- magnetic ink card reader (MICR)
- optical character reader (OCR)
- Bar Code Reader
- Microphone/Mic
2. Output Device
Output devices are those devices from which we get the result, that is, when you give any input or command to the computer, then whatever results the CPU gives by processing it, show that result to us (users) or to the users. The output device is used only for receiving. Like showing the result of any input in the monitor, listening through the speaker when the song is played, getting a hard copy of any document through the printer.
“output device The output device is used to obtain the final result”
There are many types of output devices, some of which are as follows:-
- Monitor
- printer
- Projector
- speaker
- plotter
- headphone
- UPS (Uninterruptable power supply)
3. CPU (Central Processing Unit)
It is a microchip made of silicon. The CPU is also called the brain of the computer because it closely tracks all the activity happening in the computer, as well as stores all the data and information of the computer. Understanding and processing it and providing the result is the work of the CPU itself.
It is impossible for the computer to work without a CPU, all other parts of the computer are connected to the CPU like the mouse, keyboard, monitor, sound system, etc.
CPU basically works in three parts:-
- ALU (Arithmetic Logic Unit)
- memory unit
- CU (control unit)
