Input and Output Devices: Links to topics on this page: Before a computer can process your data, you need some method to input the data into the machine.
The device you use will depend on what form this data takes (be it text, sound, artwork, etc.). An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing.
Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
Most devices are only.
