BIOS/UEFI – Acronym for basic input/output system/Unified Extensible Firmware Interface, the built-in software that determines what a computer can do without accessing programs from a disk. On PCs, the BIOS contains all the code required to control the keyboard, display screen, disk drives, serial communications, and a number of miscellaneous functions. Award, Phoenix and American Megatrends are examples of BIOS manufacturers.

- The Operating System is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs.
