What is BIOS?
BIOS stands for Basic Input/Output System. It is a type of primary program that is required for every computer. The BIOS is responsible for managing the data flow between the computer's operating system and the attached devices, such as the monitor, hard disk, video adapter, keyboard, mouse and printer. Without the BIOS, the computer’s microprocessor will not be able to connect, view, or interact with these devices. The BIOS is a ROM chip that is located directly on the motherboard.
