October 4, 2022

An input device is a piece of hardware that sends data into a computer, while an output device is a piece of hardware that receives data from a computer.

The data that is sent by the input device to the computer for processing is reproduced or displayed by the output device. While most devices are only input or output devices, some can also accept input and display output.

A system is only as good as its input and output devices. Input devices are devices that allow us to enter data into a computer system.

Output devices are devices that allow us to see or hear the results of the data that has been processed by the system. The most common input device is a keyboard, while the most common output device is a monitor.
