Questions and Answers

What is BIOS?

  • A hardware component that manages computer operations
  • A type of computer virus
  • A firmware program stored on a computer's motherboard (correct)
  • A software program stored on a computer's hard drive

What is BIOS and what is its main purpose?

BIOS is a firmware program stored on a computer's motherboard that manages and initializes computer hardware before the operating system takes control.

What does BIOS do?

  • It performs a series of checks called Power-On Self-Test (POST
  • All of the above (correct)
  • It initializes computer hardware after the operating system takes control
  • It provides low-level software services used by operating system and other software programs
