Explanation:
Detailed explanation-1: -BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
Detailed explanation-2: -The first thing a computer has to do when it is turned on is start up a special program called an operating system. The operating system’s job is to help other computer programs to work by handling the messy details of controlling the computer’s hardware.
