1. Input Functions of Computer

You know that the computer does not work without instruction, if you want to get the computer system to work, then first of all you have to give some instruction to the computer, only giving instruction to the computer is called input function of computer.Whatever instruction we give to the computer, it is received by the computer in the form of input.Note -A person gives any type of instruction to the computer through an input device. A person cannot enter any type of data into a computer without an input device.

In simple language, an input device is a medium that works to transmit the data sent by humans to the computer.There are many types of input devices, but we are going to tell you about the important input device, which everyone uses to input data into the computer.

Keyboard - Keyboard is an input device which is used by everyone. You input text type data into the computer through the keyboard.Text data like - With keyboard you can input alphabet data like - A, B, Cat, Dog, Name and you can also input number data from keyboard like - 1, 2, 999, 452 and you can also input special characters like -
, ( ), , #, *, &, , , ^, % , etc.


Mouse -Mouse is also an input and pointing device. People use mouse more than keyboard.The mouse is on the monitor screen in the form of a cursor, so that you open an application on the monitor screen and you give the intervention of opening or closing a folder or file through the mouse.

Scanner - Scanner is also an input device. Through the scanner, you enter a hard copy into the computer as a soft copy.

Bar Code Reader - Bar code reader is also an input device. Which reads the bar code of a product and sees all the information about that product in the computer.


2. Processing Functions of Computer

Processing data is a core function of the computer system, as soon as the instruction is received by the user, the computer starts executing that instruction immediately.

This second function of the computer is called the processing data function.The instruction given to the computer by the user is taken by the Execute Computer CPU, CPU also known as Computer CPU Processor.As soon as the instruction is received by the user, the CPU starts the process of executing that instruction along with its components.

That instruction is shared by the components of the CPU ( Central Processing Unit ).


Computer CPU has three main components.

Memory unitArithmetic and Logic UnitControl unit

1. Memory Unit

As soon as the data is received by the user, that data is temporarily stored in the memory unit of the computer CPU, after that, the memory unit sends the data sent by the user to the arithmetic and logic unit.

This is the only work done by the memory unit of the CPU.

2. Arithmetic & logic unit

After getting the user"s data from the memory unit, the Arithmetic & logic unit checks that data whether the data is arithmetic or logical.Arithmetic Data Means - Data related to mathematical or calculations is called arithmetic data.Logical Data Means - The instructions given by the user that contain logic are called logical data such as - instruction to play a video by the user or the instruction to open or close a software application.When the Arithmetic & logic unit gets to know what is the type of instruction sent by the user, then the Arithmetic & logic unit starts executing that instruction.

3. Control Unit

The control unit"s job is to follow the instruction given by the user.Simply put, the work of the control unit is to monitor. The control unit always checks the components of the computer system to see which components are working and which components are not.


3. Output Functions of Computer

There is a third function of the computer system, the result that comes after processing the instruction given by the user is called the output function of the computer.

The type of instruction given to the computer by the user, the computer also gives the same type of result to the user.For Example

If the user instructs the computer system to add two numbers, the computer will give an answer to the user"s addition of the two numbers.If the user instructs the computer system to multiply two numbers, the computer will give an answer to the user to multiply two numbers.If the user instructs the computer to play music, the computer plays the music.

Note -The user gets the output of his inputted data through the output device. Without an output device, the user cannot get the output.There are many types of output devices, but we are going to tell you about some important output devices, which are used in every computer.

Monitor - The monitor screen is an output device. The monitor screen is there in every computer system. The monitor is one of the main parts of the computer, without it the user cannot get the output. The monitor screen is used to display the output of the user.

Printer - Printer is also an output device. The printer prints the softcopy of the computer as a hardcopy. Printer"s job is to print.

Plotter - A plotter is also an output device. The plotter is also like a printer and the work of both is to print. The plotter is used to print vector graphics.

Speaker - Speaker is also an output device, which is used for listening to a song.


4. Storing Functions of Computer

The fourth function of the computer system is to store the output of the input made by the user.

The function of storing the user"s output is called the storing function of the computer.

Even after the output data of the instruction given by the user comes, that data is stored in the computer RAM and when you save that output data, then that data gets saved permanently in the storage device of the computer.

To explain to you, we have explained the computer"s storage device well. If you read it carefully then you will understand.

There are two types of memory in the memory unit of a computer CPU, whose names are given below.


RAM - RAM stands for Random Access Memory. Any data is stored in RAM memory only for some time after that, that data gets erased. The data inputted by the user is also stored in RAM and even after the output comes, the user"s data remains stored in RAM itself.

Learn - Different Types of RAMUntil you save the output data, your data is store in the RAM memory itself.

ROM - ROM stand for Read Only Memory. ROM memory is not for the user"s use, but the ROM memory is used by the computer system.

Note - The user can save his data permanently in the secondary storage of the computer. There are many types of secondary memory, but we will tell you about the important secondary storage which is in every computer system.

There are two main secondary storage names is given below.

HDDSDD

HDD - HDD stands for Hard Disk Drive. This storage device is in almost every computer system, in this storage you can save any type of your data permanently.

SSD - SSD stands for Solid State Drives. It is also a storage device. This storage device did not come in the earlier computer systems, but with the computers of the fifth generation, this storage device is available in the market.In SSD also you can save any of your data permanently. SSD storage devices are faster than HDD storage devices.


FAQ Related to Working of Computer

1. What is the working process of computer?

There are four working processes of a computer system, which are given below.

The computer accepts the input data from Input Devices by the user.The computer system transfers the user data to the memory unit of the CPU for processing.After processing the data, the user gets the output, through the output device.After getting the output, the computer waits for the user"s instruction whether to save the output data permanently or delete it.

2. What are the 5 basic operations of a computer?

There are five basic operations of a computer system is given below.

Inputting.Processing.Outputting.Storing.Controlling.
