Presentation. Computer is an electronic device which takes input and gives output! In computing, input/output, or I/O, refers to the communication between.

processing system (such as a computer) and the outside world. Inputs are the signals or data received by the system, and outputs are the signals or data sent from it. I/O devices are used by a person (or other system) to communicate with a computer. For instance, keyboards and mice are considered input devices of a computer, while monitors and printers are considered output devices of a computer Input/output units EARLY DEVICES : Unit record equipment : Before/
