Hello, Today I’m going to show you an easy way to learn what is computer system and the best definition of computer.
In this post, I will explain How does a computer system work in detail.
This Article is Best on the whole internet.
I Guaranteed you, after reading this article you will not need to read any other Articles. In fact, our readers satisfied in this blog post.
What is Computer Definition?
A Computer is an electronic Machine/Device which accepts data from the user stored in Memory perform Mathematical as well as logical operation and gives the required results or information, is called a computer.
A computer is a very smart device that runs on electricity.
A computer is a programmable machine that works on the instruction given by the user.
The computer runs only by the combination of hardware and software.
The word computer is derived from the Latin word "computare". The word "computare" means Calculation.
That is, the computers of earlier times were capable of calculating only.
Earlier computers were used only for calculating. Like - adding or subtracting a number.
But nowadays computer systems can also do calculations, and are also capable of performing many other tasks.
Due to these characteristics of computers, today the whole world is using computers everywhere. Such as - schools, colleges, offices, banks, airports and etc.

How does a Computer Work?
Today I discuss how the computer system works and what steps does the computer does by following any work.
Computer Basically works on four modules, which are given below.
- Input
- Processing
- Output
- Storage
1.) Input
Some kind of data is inputted by the user or we can say in easy language that the user inputted some instruction.
We can input any type of data from a computer with the help of input devices. Input devices Such as - Keyboard, Mouse, Microphone.
Q. Which types of data input by the Keyboard ?
Ans - With the help of keyboard, we can input any type of text data. Like - a word or any number.
Q. Which types of data input by the Mouse ?
Ans - With the help of Computer Mouse, we can input clickable type data on the monitor screen.
Like - Open and close any File, Folder, Applications and Minimize, Maximize and close the Computer screen.
Q. Which types of data input by the Microphone ?
Ans - With the help of a Microphone, we can input Voice data on the computer.
Like - I say open my computer icon, then the computer recognizes voice data and open my computer.
Today computer is very smart and the computer accepts all types of instructions given by the user.
I hope you Understand.
2.) Processing
Any type of data that is inputted by the user, that data or instruction computer understands which type of data or instruction is.
Like is arithmetic data or logic data.
All the processing function is done by the CPU. A CPU is a microprocessor chip.
This microprocessor chip is very fast than the human brain.
Note - When a computer processes input data, that data is temporarily stored in computer RAM while processing.
I hope you understand computer processing.
3.) Output
When we input some kind of data, that data is processed after input, which comes after processing is our output.
The output of which is visible to us on the monitor screen.
There are several types of output devices.
We have a soft copy, and we have to print the soft copy.
So we instruct the computer to print. So the output we get will be received by the printer as a hard copy.
I hope you understand.
4.) Storage
Space is required to display the result that comes after processing. Output results without storage will not be displayed.
A computer has a storage device to store data.
There are two types of storage devices, 1. Temporary Storage 2. Permanent storage
Whenever the computer displays the results after processing any data, it is the temporary data which is stored in the temporary storage RAM.
If we save the result that comes after processing, then that data is saved from temporary storage RAM to permanent storage.
I hope you understand.

Basic Parts of Computer System
There are Four Main Parts Of Computer. These four devices are meet together and build a computer.
If there is no one of these devices, then we cannot call it a computer.
These four devices have a different main role in our computer system. These four devices are interlinked.
These four devices are also known as Main Parts of Computer, which are given below.
- CPU
- Keyboard
- Mouse
- Desktop Screen
1.) CPU
Central Processing Unit
The full name of the CPU is Central Processing Unit.
The CPU is also called the brain of the computer.
The CPU controls the entire computer system. It is also the main part of a computer.
2.) Keyboard
Computer Keyboard
Keyboard is an input device. We use the keyboard to input any type of data into the computer. The keyboard is also a main part of the computer.
3.) Mouse
Computer Mouse
The mouse is also a pointing device and input device.
The mouse is used to open a folder, icon and any application on the computer screen.
The mouse is the main part of a computer.
4.) Desktop Screen
Desktop Screen
Monitor is an output device. It is appear like a TV.
Monitor implements any output in soft copy. Monitor is the main part of a computer.
Benefits of Using Computer
