BIOS contains :

(i) Operating System Program
(ii) Bootstrap Program
(iii) Application System Program
(iv) Convert Character to Code Program

  • A.(i) and (ii) are correct
  • B.(ii) and (iii) are correct
  • C.(iii) and (iv) are correct
  • D.(ii) and (iv) are correct

Answer: D

The BIOS (Basic Input Output System) is stored on a chip in the computer. It holds the bootstrap program, which starts the computer and loads the operating system, and the routines that convert the characters typed on the keyboard to codes and handle other basic input and output. The operating system and application programs are not in the BIOS, they are loaded from disk. So (ii) and (iv) are correct, option (D), and the options with (i) or (iii) are wrong.
