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.

Definition
of Input Device
The electronic
device, equipment or instrument by which data is inputted. That is, by which
figures, words or any kind of instructions are sent to the memory. It is called
Input Device. All device of computer Are also called Input Device. By which
computer users give their instructions or data to the computer. As; Keyboard,
Mouse, Scanner, Light Pen and Microphone etc.
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.

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.
Types of
Input Device
Above you
have read a lot of information about Input Device. Here you will know the type
of Input Device. Since input device are divided into two categories.
1. Keyboard

2. Mouse
3. Scanner
Scanner is also an Input Device. By this a paper-like object
such as; Documents, Pictures, Articles and the paper itself are also scanned
and made in digital from. It can be kept in digital from in the computer for a
long time. Nowadays it is being used more to make the book an e-book.
4. Microphone
5. Joystick

makes it easy to play games and without any computer knowledge, you can play
games in computer.
6. Webcam
Web Camera itself is called webcam. It is just a type of
camera. Which comes under computer hardware. It is an Input Device. Which makes
pictures or videos in digital form. It is mainly used for recording video or
live video streaming.
7. Touchscreen
Touchscreen is a pointing input device. It is used to give
location instructions to the computer. Data is filled by touching it. Touchscreen
can be used to control any part of the computer. Touchscreen can do every
function of the mouse in the computer. Today its use has increased a lot. It is
mainly done in smartphones, ATMs, computers and laptops etc.
8. Light Pen
Light Pen is an input device similar to touchscreen. It is
like a stick. It is used to select or modify the text or data displayed on the
screen. It is also used in photography on computers.
