THE DIFFERENCE BETWEEN INPUT AND OUTPUT. BY FRASER HINE.

THE DIFFERENCE BETWEEN INPUT AND OUTPUT. BY FRASER HINE WHAT IS INPUT? Any information or data thats entered or sent to the computer to be processed is considered input. Input or user input is most often sent to the computer using an input device such as a keyboard or mouse. The picture is an example of input being sent from the computer keyboard to the computer.

Input & Output Computer Devices Presented by, Name: Liew Geok May (37) Class: 3I.

Are InPut & Output computer devices? The term “input and output” is used to describe any program, operation or device that transfers data to or from a computer and to or from a peripheral device. Every transfer is an output from one device and an input into another. Devices such as keyboards and mouses are input-only devices while devices such as printers are output-only. A writable CD-ROM is both an input and an output device. Click here to see examples of INPUT devices/
