RAM

Random Access Memory; the memory that is available on a computer for storing data and programs. It is automatically erased when the power is turned off. Information in the Random Access Memory that needs to be stored for future use must be saved onto a disk or tape.

ROM

Read Only Memory; a system's permanent, stored instructions, which are never changed; it holds its contents even when the power is tuned off. Data is placed in Read Only Memory only once, and stays there permanently. Read Only Memory is generally installed by the manufacturer as part of the system.

output

The computer-generated information that is displayed to the user in some discernible form such as a screen display, printed, page, or sound; component that gets info out.

Input

The data that is entered into a computer; physical device that accepts data and puts it into a computer

processing

Charles Babbage

designed mechanical calculating machines; his ultimate calculator is called the Analytical Engine; "Father of Computing"

hardware
