Complimentary Metal Oxide Semiconductor

CMOS is a low-power, low-heat transistor often found in two components:

1) Processor: CMOS technology provides an unusually high degree of speed while keeping heat, which is always a problem with processors, completely under control.

2) Memory: CMOS memory will maintain information, including the date and time, as well as other basic system settings. The low-power consumption of CMOS allows the memory to be powered by a single small Lithium battery, which lasts for many years. Powered by battery, the information stored in CMOS memory remains available even when the computer is turned off. This also enables this data to be accessed easily by BIOS at boot-up.
