What is an input device?
Input devices are devices by which users send their data or instructions to the computer. Input-device is a hardware and peripheral device used to send data or instructions to a computer.
In other words, the device which is used to give instructions to the computer is called input device. It helps the user to communicate with the computer.
Input device is the device that transmits our instructions to the computer CPU following our given instructions, this we call input-device.
The device by which we give instructions to the computer, that device is called input device. That is, the device through which the computer takes data or information from us is called input-device.
Apart from this you should know that input device is also an electronic device. These devices are part of the computer. Any device from which we give input to the computer. In simple language it is called input device.
Some examples of input devices, which will be easy for you to understand. eg. We give input to the computer through all these input devices like keyboard, mouse, scanner, light pen, micro phone etc. Let us understand the example in detail.
Input device definition
The device by which data or instructions are directed into the computer is called an input device. Define in simple words, data or instructions are inputted into the computer by this device.
The devices through which data or instructions are inputted into the computer by the user are called input devices. This device transmits the information given by the user to the computer.
Input device type?
Mouse
Mouse is a hardware and input device. Through this we give instructions to the computer. With the help of mouse, we can move the arrow icon visible in the computer, which is called cursor or pointer, and can easily click on any button or menu visible on the screen.
Mouse works only through pointer or cursor in computer, so it is also called as pointer device. It acts as an interface between the computer and the user.
Because the user gives instructions or input to the computer through the mouse. With the mouse it is possible to move to any part of the computer. Through this we can easily go to any part of the computer.
A mouse is a small pointer device used by the user by placing the mouse on a table surface or on the mouse foot. It acts on the screen through a cursor.

How many types of mouse are there?
There are many types of mouse. Well, there are different types of mouse available in the market. These have been talked about on the basis of different design, look, interface and connectivity.
There are mainly two types of mouse in the market, optical mouse and wireless mouse. Apart from this, there are many types of mouse. Let us know in detail about all types of mouse.
1) optical mouse
The optical mouse uses a light source. It uses optical electronics, including an LED and a light detector, to track the position and movement of the mouse.
The most used in today’s time is the optical mouse. Under this mouse you will see a red light. These have a very small (small low resolution) camera. Which takes 1000 or more pictures every second.
Optical mouse is a modern device that is being used at present. In this, a Light Emitting Diode (LED) is used to detect the distance traveled by the mouse.
This mouse is a better and standard look than the mechanical mouse I used earlier. Because they are more reliable than all other types of mouse. And it requires maintenance.
But it depends on the way you are using it and the type of surface. on which they are operated on. You should place it above the touch pad for better experience.
2) Mechanical Mouse
A mechanical mouse is a mouse that uses a metal or rubber ball inside. That’s why it is also called ball mouse.
When this ball moves or moves in any direction, the sensors in it detect this motion. And move the pointer or cursor in the same direction on the computer screen.
In the olden days these icons were the most used. Now optical mouse has replaced them. The first mouse had a wheel, that is, a small metal wheel, which made it difficult to move or move the mouse in every direction. But with the advent of mechanical mouse it became easier.
Mechanical mouse are of corded type i.e. come with wire only. Their performance is high, but they require special cleaning from time to time.
Mechanical mouse is no longer in vogue, it has become obsolete as they have been replaced by optical mouse.
3) Wireless Mouse
A wireless mouse is a mouse that does not have wires of any kind. No wires or cables are used to connect these mouse to the computer.
They are also known as cordless mouse. Connecting them to computer for connectivity instead of cable, bluetooth, wifi, infrared etc. is used.
A mouse that does not use any type of wire or cable connection is called a wireless mouse. Wireless technology is used to connect such a mouse to a computer.
To connect it, you’ll need to plug a USB receiver into your computer. These mice run on batteries, and use the same technology used in optical mouse to locate the sensor.
4) Trackball Mouse
Optical mouse technology is also used in this mouse. And its design, look and texture are also similar to optical mouse. The only difference is that a trackball is used to control it.
The user moves the trackball with his finger or thumb to give instructions to the computer. This type of mouse has very low speed. And it takes longer to run.
5) Stylus Mouse
Stylus mouse is like a pen, just as we write by pressing the pen in the fingers, similarly this mouse is also operated by pressing between the fingers.
A small wheel is also attached to it. which is carried up and down. It is used to move the page up and down.
Stylus Mouse is also called Gstick Mouse. Because it resembles a pen stick, and was invented by Gordon Steward, it is called the gstick, with the “G” standing for Gordon.
keyboard
Keyboard is an input device of computer. A keyboard has many buttons. It is the peripheral of a computer, which is similar to the keyboard of a typewriter. The keyboard is partly similar to a typewriter’s keyboard, so it is defined as the seat of the typewriter-like keys.
Keyboards are mainly used in computers for typing, data entry like text, numerical data, symbols, commands and many other types of data.
Input is given to the computer through the keyboard. After which that data is converted into machine language. So that the CPU (Central Processing Unit) can understand that data and information or instructions.
How many types of keyboards are there?
There are many types of keyboards. There are mainly two types of keyboards known to most of the people, computer desktop keyboard and laptop keyboard.
Apart from this, there are many types of keyboards, which most people do not know about. Let us know in detail about all types of keyboards.

Barcodes are black vertical lines with a lot of information hidden inside. Such as – Product Name, Cost, Price, Batch Number, Manufacture Date, Expiry Date, Company Name and Description etc.
Difference between input device and output device?
| INPUT DEVICE | OUTPUT DEVICE |
|---|---|
| The devices through which input is given to the computer are called input devices. | After giving input, the device from which the user gets the output is called output device. |
| It receives data from the user and sends it to the processor. | It receives the data from the processor after processing and sends it to the user. |
| It receives data or instructions from the user. | It provides data or instructions to the user. |
| These are hardware devices through which the user inputs data. | These are hardware devices through which the user receives data. |
| Example:- Keyboard, mouse, microphone, scanner, light pen etc. | Example:- Monitor, Printer, Projector, Speaker etc. |
