BIOS refers to a computer system used by the CPU and is responsible for performing various startup procedures when you start the computer.

It works professionally to keep your PC's basic operations working properly. It comes included with all the instructions relating to the loading of basic computer hardware. It has a test named as POST-Power-On Self-Test-that intelligently indicates whether your computer meets up all the requirements for the boot or not. If it does not meet them all, it starts up a beeping sound to indicate your computer's malfunctioning.

Coordination Among Components

Furthermore, after helping the computer is booting up, BIOS provides some low-level drivers and various other details that are helpful in proper coordination of all the parts of the computer.
