What Is a BIOS?

BIOS, short for Basic Input / Output System, controls your computer boot process. When you start your computer boot, BIOS starts the power-on self-test (POST) and passes the control over to the boot loader that boots your computer OS.

BIOS is a low-level system software and it is stored on a chip on your motherboard, unlike the operating system which is stored on computer hard drive.

Some newer computers come with UEFI firmware instead of the tradition BIOS. Its function is the same as BIOS, and it is also a low-level system software.
