BIOS

What Is BIOS

BIOS is non-volatile firmware used to perform hardware initialization during the booting process, and to provide runtime services for operating systems and programs. The BIOS firmware comes pre-installed on a personal computer's system board, and it is the first software to run when powered on.

Well, it’s much more than a thing or code or a program. The Basic Input/Output System or BIOS in a PC typically forms the backbone of a computer, even though most users or even PC makers won’t admit it. To your computer’s operating system (OS), BIOS is what John the Baptist was to Jesus of Nazareth, to put it really figuratively.
