Input devices
An input device can send data to another device, but it cannot receive data from another device. Examples of input devices include the following.
Keyboard and Mouse - Accepts input from a user and sends that data (input) to the computer. They cannot accept or reproduce information (output) from the computer.Microphone - Receives sound generated by a user or other source (input) and sends that sound to a computer. It cannot receive and reproduce (output) sound sent by other devices.Webcam - Receives images generated by whatever it is pointed at (input) and sends those images to a computer. It cannot receive and reproduce (output) images sent by other devices.
Output devices
An output device can receive data from another device and generate output with that data, but it cannot send data to another device. Examples of output devices include the following.
Monitor - Receives data from a computer (output) and displays that information as text and images for users to view. It cannot accept data from a user or other source and send that data to another device.Projector - Receives data from a computer (output) and displays, or projects, that information as text and images onto a surface, like a wall or a screen. It cannot accept data from a user or other source and send that data to another device.Speakers - Receives sound data from a computer or other device (output) and plays the sounds for users to hear. It cannot accept sound generated by users and send that sound to another device.

Answer:
Input devices sends information to a computer system for processing, and output devices reproduce or displays the result of that processing. Input devices only allow for input of data to a computer and output devices only receive the data from another device
