Option 3 is correct, i.e. Basic Input Output System.

  • BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on.
  • It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
  • BIOS is a firmware, in short. It is stored on a chip on a part of the computer motherboard and is basically a set of instructions that run to help load the operating system.
