what exactly is cmos?

Answer 1

Non-volatile BIOS memory refers to the memory on a personal computer motherboard containing BIOS settings and sometimes the code used to initialize the computer and load the operating system. The non-volatile memory was historically called CMOS RAM or just CMOS because it traditionally used a low-power CMOS memory chip (the Motorola MC146818, or one of its higher-capacity clones), which was powered by a small battery when the system power was off. The term remains in wide use in this context, but has become a misnomer. The non-volatile BIOS memory in modern computers is generally an EEPROM or Flash memory chip. There is still a backup battery involved, but its role is not to maintain the data stored in the RAM, only to keep the RTC chip operational.

Answer 2

Complementary symmetry metal oxide semiconductor(CMOS) devices use both P-channel and N-channel MOS devices connected end to end. CMOS ICs are know for there exceptionally low power consumption. The CMOS family of ICs also have the advantages of low cost, simplicity of design, low heat disipation, good fan-out, wide logic swings, and good noise-margin performance. Most CMOS families of digital ICs operate on a wide range of voltages.
