A microprocessor is the brain of any computer, BIOS is the instruction to the microprocessor, even to wake up and launch itself. Hence it is the first layer between software and hardware. It is one who directly interacts with bare hardware.

Whenever we start our system, microprocessor passes control to the BIOS which is present at the EPROM. It checks and ensures the exact location of every component and then loads the operating system on the ROM (Read only memory) from the hard disk of the system. In this way, BIOS eases the responsibility of Operating System to know about the address of associated devices and basic input-output flow.
