Computer Systems

Input:

Whatever goes into the computer. Input can take a variety of forms, from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input device.

Output:

Computing: A result produced by a computer that is internal to the system (from one program or process to another) or external to it (from a program or process to an output device) but internal to an output device (modem, monitor, printer, etc.).

Storage:

A device consisting of electronic, electrostatic, electrical, hardware, or other elements into which data may be entered, and from which data may be obtained as desired. See also ammunition and toxic material open space; bin storage; bulk storage; igloo space; large-lot storage; medium-lot storage; open improved storage space; open unimproved wet space; small-lot storage.

Processor:

A processor, or "microprocessor," is a small chip that resides in computers and other electronic devices. Its basic job is to receive input and provide the appropriate output. While this may seem like a simple task, modern processors can handle trillions of calculations per second.
