What is Input Device ? Functions and types of Input Device .

What is Input?

 Do you know the meaning of the word ‘input’?  Data sent to the computer for processing is considered input.  Providing some data or information to the computer is known as input.  Now, let us understand what an input device is.

What is Input Device?

 An input device acts as a hardware component that transmits data to the computer, allowing you to interact with and take control.  The keyboard and mouse are the most widely used and earliest input devices for computers.  However, various other devices also contribute to data input into the computer.

 An input device allows users to send data, information, or control signals to a computer.  The central processing unit (CPU) of a computer receives input and processes it to produce output.  This interaction is important for seamless communication between users and computers.

Definition of Input Device –

 A device, instrument, or mechanism through which data is entered.  In other words, it transports numbers, words or any kind of instructions to the memory.  This is what we call input device.  All those devices of computer are also called input devices.  They allow the computer user to provide instructions or data to the computer.

 Examples include Mouse, Keyboard, Scanner, Microphone, Light Pen and more.  These tools play an important role in enhancing user experience and interaction with computers.

10 examples of Input Device –

 Here we have given 10 examples of Input Devices, which you can read below.

  • keyboard
  • Mouse
  • Scanner
  • Joystick
  • Microphone
  • Light Pen
  • Web Cam
  • touch screen
  • Trackball
  • Barcode Reader

Functions of Input Device –

 The prmary function of an input device is to provide input to the computer, in whatever form it may be.  This input initially enters the computer memory and is then processed by the central processing unit.  After this the output is received.

Types of Input Devices –

 Here you will know the types of Input Devices which have been divided into two parts.

1. Manual Input Device :

 With a Manual Input Device, you provide computer instructions manually.  For example, when you need to type something on a computer, you simply press keys on the keyboard using your fingers.  This practical approach ensures direct control over computer actions.

2. Direct Input Device :

 Using a Direct Input Device eliminates the need for extensive external assistance in directing the computer.  These devices enable direct data input into the computer, as seen with Scanner, Optical Mark Reader, Barcode and others.
