Explanation:
CMOS is a memory chip that is designed to draw very little current. This memory is used to
contain system configuration settings, BIOS passwords and time and date. BIOS is the Basic
Input/Output System that could be referred to as the motherboards firmware. BIOS is contained on
a chip that usually is soldered to the motherboard and should not be replaced. Flashing a BIOS is
the term used when upgrading the program (or firmware) on the BIOS chip.
