What is BIOS? Definition: BIOS is a program stored in a computer’s motherboard, it starts the operative system once you turn the computer on.
When BIOS starts up a computer, it first determines whether all of the attachments devices are in place and working propertly and then it loads the operating system into the computer’s random access memory (RAM).
The BIOS is a set of procedures that controls the flow of data between the operating system and devices such as hard drive, video card, keyboard, mouse and printer.
The BIOS is typically placed in a ROM chip that comes with the computer. This ensures that the BIOS will always be available and will not be damaged by disk failures.
Some computer manufacturers copy the BIOS from ROM to RAM each time the computer is booted. This is known as shadowing.
