CMOS stands for Complementary Metal-Oxide Semiconductor.

This handles your computer’s clock, the date, the passwords (if any).

This is the part responsible for controlling the devices on the computer:

  1. Clock
  2. Date
  3. Passwords (if any)
  4. Intrusion Security of the CPU itself
  5. Processor
  6. Physical RAM
  7. Keyboard
  8. Mouse
  9. Available and assigned IRQ for the parallel port (printer port)
  10. USB
  11. Video card
  12. Sound card
  13. Network card
  14. Internal modem
  15. Hard drive
  16. DVD/CD drive
  17. Floppy disk drive
  18. Any firewire IEEE adapters

CMOS sets the configuration for all the attached devices. For example the processor, it controls the speed setting, like a Pentium 4 3.06GHz 533MHz FSB Socket 478 Level 2 512kb cache multithreading, it sets whether the multithreading option is enabled or disabled.
