What is the difference between an input and output device?

Input and Output exampleTo understand the difference between an input and output device, you must understand the difference between input and output. Any information or data that is entered or sent to the computer to be processed is considered input and anything that is sent from the computer to an internal or external device is output.

An input device, such as a computer keyboard or mouse, can send information (input) to the computer, but it cannot receive information (output) from the computer.

An output device, such as a computer monitor or printer, can receive information (output) from the computer, but it cannot send information (input) to the computer.

An input/output device, such as a CD-RW drive or USB flash drive, can send information (input) to a computer and receive information (output) from a computer.
