Input and Output exampleAlternatively referred to as I/O, Input/output is any software or hardware device that is designed to send and receive data to and from a computer hardware component. For example, a computer mouse can is only an input device, because it can send data but doesn't receive any data back. A computer monitor is an output device; it can display information but doesn't send data back to the computer.

A good example of an I/O device is a Modem that connects to the Internet and can send and receive information. With a database a I/O device refers to a hard drive.
