The BIOS is responsible for booting the computer. It performs a power-on self-test (POST) to make sure the computer is functioning properly, and then it loads the operating system. The BIOS also provides a basic input/output system (BIOS) that allows the user to interact with the computer, and it contains a set of built-in routines that handle common input/output tasks.
