CMOS
Acronym for complementary metal-oxide semiconductor. In computers, CMOS
memory chips are often used for NVRAM storage.
COMn
The device names for the first through fourth serial ports on your computer are
COM1, COM2, COM3, and COM4. The default interrupt for COM1 and COM3
is IRQ4, and the default interrupt for COM2 and COM4 is IRQ3. Therefore, you
must be careful when configuring software that runs a serial device so that you
don't create an interrupt conflict.

systems, expansion cards, or peripherals that are compatible with DMI.
Each component is made up of groups and attributes that are defined as

or between the microprocessor and a peripheral device such as a disk drive or
the keyboard.
