This document discusses computer input and output devices. It defines input devices as peripherals that send data to computers by allowing users to communicate with computers. Output devices are defined as devices that send the results of data processing to users, allowing computers to communicate with users. Examples of common input devices include keyboards, mice, webcams, and microphones, while common output devices include monitors, printers, speakers, and projectors. The document provides examples of how input devices send data to computers to be processed, and how output devices receive the processed data from computers.

Input Device
 A peripheral device used to send data to the compute
rs.
 Allow users to communicate with computers.
 Convert external signals into data.
Output Device
 A device used to send to the user the results of data
processing in the computer.
 Allow computers to communicate with users.
 Transfer data out in the form of text, images, sounds
or other media.
NOTE:
 An input device can send data to another device, bu
t it cannot receive data from another device.
 An output device can receive data from another
device, but it cannot send data to another device.
