What does CMOS stand for?

  1. Controlled Metal-Oxide Semiconductor

  2. Complementary Metal-Oxide Semiconductor

  3. Compact Metal-Oxide Semiconductor

  4. Computed Metal-Oxide Semiconductor

The correct answer is: Complementary Metal-Oxide Semiconductor

CMOS stands for Complementary Metal-Oxide Semiconductor. This is a type of integrated circuit technology that uses both p-type and n-type metal-oxide-semiconductor (MOS) transistors. Option A (Controlled Metal-Oxide Semiconductor) is incorrect because there is no such term in the field of integrated circuit technology. Option C (Compact Metal-Oxide Semiconductor) is an incorrect choice because the term "compact" does not accurately describe the technology used in CMOS. Option D (Computed Metal-Oxide Semiconductor) is incorrect because the term "computed" does not accurately describe the technology used in CMOS.
