1. CMOS (Complementary Metal Oxide semiconductor)
  Abbreviation of complementary metal oxide semiconductor. Pronounced see-mos, CMOS is a widely
used type of semiconductor. CMOS semiconductors use both NMOS(negative polanity) and PMOS
(positive polanity) circuits. Since only one of the circuit types is on at any given time, CMOS chips
reqire less power than chips using just one type of transistor. This makes them particularly attactive
for use in battery-powered devices, such as portable computers. Personal computers also contain
a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.
