Input, Output, Touch Screen and Operating Systems

Input and Output???

Any information or data that's 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.


Any information that has been processed and comes from a computer or computer device is considered output. When someone is viewing output, they're seeing it on an output device such as a computer monitor or a hard copy print out. The picture shows output being sent from the computer to a printer

What is a Touch Screen?

A monitor or other flat surface with a sensitive panel directly on the screen that registers the touch of a finger as an input. Instead of being touch-sensitive, some touch screens use beams across the screen to create a grid that senses the presence of a finger in close proximity.
