Basic Input/Output System
A technical computing term used to describe what is coded into a PC's ROM to provide the basic instructions for controlling the system hardware. The operating system (OS) and application programs both directly access BIOS routines to provide better compatibility for such functions as screen display. Some makers of add-in boards, such as graphics accelerator cards, provide their own BIOS modules that work in conjunction with (or replace) the BIOS on the system's motherboard.
