Input Devices of Computer

The input devices of a computer system can be described and explained as electromagnetic devices that accept information and data from outside the world and translate this given data and instruction into machine language that machines or computers can easily understand.

This machine language is also known as "Binary Language," which uses 0s and 1s for processing and understanding.

The input devices of computers act as a bridge between Computers and users.

The data presented to the Computer are translated and processed for further use; this data can be saved in computer memory almost permanently.

The computer keyboard and mouse are considered to be prime examples of input devices.

Let us discuss input devices in more detail.

1. Mouse

The computer mouse is a pointing device used to point to a certain area on the screen and also to click and drag files and folders from one location to another.

The mouse is the most well-known and famous pointing device, which has two clickable buttons, one on the right side and the other on the left side, and a wheel in the center for scrolling.


The mouse is utilized fundamentally in applications or projects or with GUI Technology (Graphical User Interface).

The mouse is relatively inexpensive and the most used input device also primarily used in GUI {Graphical User Interface} applications.

There are three types of the mouse
  • Mechanical Mouse
  • Optical Mouse
  • Infrared (IR) or radio frequency cordless mouse

2. Keyboard

The keyboard is primarily used for entering data, information, and instructions into the computer system.

With the mouse, the keyboard is also considered one of the most used input devices.

The modern Computer’s keyboard consists of numerous keys; some keys are used to enter numeric values.

Some are used to enter alphabets, and also used for entering special keys and special symbols.

Some multimedia keys are used to play sound and videos.

The standard keyboard has 101 keys, but today, the keyboard comes with 102 and 124 keys for better and enhanced performance.

There are three types of keyboard
  • Normal Keyboard.
  • PS/2 Keyboard.
  • USB keyboard.
  • Wireless Keyboard.

3. Scanner

The scanner is also considered to be the input device of the Computer.


The scanner is used to scan any document like images, pictures, documents, and text on paper and later can be stored on a computer hard disk permanently.

There are 2 types of scanners
  • Hand-Held Scanners
  • Flatbed Scanners

4. Trackball

The trackball is a pointing device, just like a mouse.

The trackball usually is built-in with laptops and notebooks. They are used to navigate on the area of the screen horizontally, and diagonally also are free movers.


Fingers use a trackball to select, click, and drag files and folders from one location to another.

They are small in size, more often square in shape. It is very easy and efficient to use and can be installed in less space.

5. Joystick

The joystick is famously used for playing games and in CAD {Computer Aided Design}.


In the modern keyboard, a joystick is pre-installed.

The joysticks can move LEFT, RIGHT, UP, DOWN, and a push-button at the top.

6. Light Pen

The Light pen is a pointing device and one of the input devices that looks similar to a pen.

They are equipped with light sensors that are activated when it is touched or used.

It is used for choosing and drawing pictures; it sends a flag and PC, which distinguishes the cursor’s position.

7. Touch Screens

Touch screens are capable of displaying and retrieving data and information on the net.

Touch might be known as touching the screen with fingers. They can be detected by fingers or pen-shaped stylus.

8. Optical Card Reader (OCR)

OCR is a mechanical or electronic gadget or device that can translate images, pictures, documents, or manually written content into coherent machine shapes.

OCR also works like a scanner that can check documents, pictures, images, and composed content and can store it in memory, which later can be contrasted with the previously stored data.
