Short for negative-channel metal-oxide semiconductor, and pronounced en-moss, a type of semiconductor that is negatively charges so that transistors are turned on or off by the movement of electrons. In contrast, PMOS (positive-channel MOS) works by moving electron vacancies. NMOS is faster than PMOS, but also more expensive to produce.
