What is input in a computer system?
The "Input" term used in computer refers to one of the three
major computer items: Input, Processor, and Output. Some of the
"Input" items are Keyboards, Mouses, Touch Pads, etc. Furthermore,
in programming, "Input" is used when the programmer wants the user
to input (enter) information such as his name. So, "Input" means
what is sent TO the computer. On contrary, what is sent FROM the
computer is "Output" such as Screens, Printers, etc.
