A Computer is an electronic devices that can perform activities that involve mathmetical, logical and graphical manipulations. INPUTPROCESSOUTPUT

Devices used to provide data and instruction to the computer are called input devices.

MOUSE KEYBOARD SCANNER MICROPHONE

A Mouse is used to print to and select option displayed on the monitor. A mouse may have two or three buttons.

Keyboard:- The keyboard is used for typing text into the computer. it is also known as the standard input device. the most commonly available computer keyboard has 104 keys. 6 © Franz J. Kurfess

A Scanner is used to make an exact copy of a picture or a photograph.

A microphone is a devices used to record sound. microphones convert sound waves into audio signals.

Any device that is capable of representing information on a computer is called an Output Device.

 Monitor  Printer  Speaker

A monitor is used to display information from the computer. The monitor displays texts and graphics.

A Printer is used to transfer data from a computer into paper. The different types of printers are dot matrix printer, inkjet printers and laser printers.

speaker are used to play sound. Speaker s allow you to listen to music and hear sound effects and spoken text using your computer.

Therefore, input device provide data and information and output devices representing information on the computer. so both devices helps to performs a specific function.
