begins POST by testing the processor and initializing the hardware.
As POST proceeds, BIOS test all the hardware, detects the memory,
and initializes the chipset and other controllers according to
information defined by the user and saved in the CMOS chip. When
POST is completed, the computer is initialized and BIOS turns
control of the computer over to an operating system such as DOS.
37. Serial Port: An I/O port used to connect a mouse, scanner, or any other
serial interface device to the computer.
38. SIMM/DIMM. (Single/Dual In-line Memory Module) A narrow printed circuit
board about three inches long which holds a few memory chips.
Single-sided modules only have chips on one side, while doubles
have chips on both.
39. SMI: (System Management Interface) A BIOS override function allowing the
computer to go directly into power conservation or "green" mode
without waiting for a certain amount a time specified in the BIOS
to elapse.
30. UART: (Universal Asynchronous Receiver and Transmitter) An intelligent
microchip for a serial interface which carries out the
serialization of parallel data and the insertion of start, parity,
and stop bits, or the parallelization of serial data and the
separation of start, parity, and stop bits.
41. USB: (Universal Serial Bus) A bus designed to allow the peripherals to
plug into a hub on the mainboard and or other peripherals
communicate directly with the chipset, thereby eliminating
expansion cards. Some chipsets do not support USB.
