What is Input Device? Its Definition, Types and Examples

 

What do you understand by Input Device? Do you know what is Input Device? In this article, we have given complete information about Input Device. In which we have told what is Input Device, Definition of Input Device, Types of Input Device, Functions of Input Device, Example of Input Device and Name of Input Device. If you do not know about Input Device. Then by reading this article, you can get information about Input Device.

 

Every person using a computer has and should have some knowledge of the Input Device of the computer. Because Input Device is an important device of the computer. If you do not know what are Input Device, how many types of Input Device are there and what is the function of Input Device. Then by reading this article, you can know about Input Device. But if you have knowledge of Input Device. Even then you can read this article.

 

From this article, you will also get to learn something new about Input Device. Here I have also explained Input Device in easy language. Let us first know what is Input Device. But what is Input Device? Before knowing what is Input? That is, it is very important to know the meaning of Input. This will make it easier for you to understand the Input Device.

 

What is Input?

Do you know what is Input and what is the meaning of Input? Input means to Input or invest. That is, when we invest or invest in someone. Then it will be called Input. Similarly, when data or information is given for processing in computer. Then it is also called Input. To operate the computer, the first action is to input the computer. Which means giving some data or information to the computer. Which also includes giving instructions or commands to the computer. Let us now understand Input Device, what is Input Device.

 

What is Input Device?

Input Device come under the hardware part of the computer. If you have little knowledge of computer. Then you will know that a computer is made up of hardware and software. Hardware also has many types of equipment. Some of those hardware device are called Input Device. Input Device are external hardware parts of the computer. Because of which it can be seen, touched and experienced very easily.

 

Each Parts of the computer has some work of its own. Similarly, input Device also has an important function. Through this, orders are given to the computer. Just as a person has to speak, write or indicate something to give an order. So that he can understand what he has to do. In the same way, to order the computer from the Input Device, something has to be said, written or given some kind of signal. As; Device such as Microphone, Keyboard for writing and Mouse and Touch Screen for signals are used to give commands to the computer by speaking.

 

To do any work from the computer, the computer is instructed from these devices. Since the computer itself does not work. It is necessary to give input to it to get any kind of work done. That is why Input Device is considered as an important device. Generally, the instructions to the computer are given in the form of data and the basic Input Devices of the computer are considered to be the Keyboard and mouse.

As we have said that the devices that give input to the computer are called Input Device. If you have seen the computer and you also run the computer. Then according to this definition, think once and see which device is there in the computer. Through which you can give input to the computer. If you are not able to do this. Then for you we have given below 10 examples of Computer Input Device.

 

10 Examples of Input Device

Here we have given 10 examples of Computer Input Device. See which of these Input Device you have and if so. Then what is the function of that Input Device. Below we have explained the functions of Input Device.

1.    keyboard

2. Mouse

3. Trackball

4. Joystick

5. Scanner

6. Microphone

7. Web Cam

9. Light Pen

10. Barcode Reader

Functions of Input Device

The main function of Input Device is to give input to the computer. Be it any way. Normally that Input first goes to Computer memory. After which that input is processed by the Central Processing Unit. After that the output is received. It can also be said that the work of Input Device is to convert our instructions into electric pulse. Which is expressed by Binary Digits.

 

For example when we write something with the help of keyboard. Then every button pressed on the keyboard gives the Electric Signal to the Computer and similarly the computer receives Input from the keyboard and does its work.
