BIOS
Basic input/output system. It’s a kind of software including all in/out control
code interface in PC. It will do hardware testing while system is boot-
ing, then system runs, it provides an interface between OS and hardware.
BIOS is stored in a ROM chip.
BUS
In a computer system, it’s the channels among different parts for exchang-
ing data; it’s also a group of hardware lines. BUS here refers to part lines
inside CPU and main components of memory.
Chipset
Integrated chips for executing one or more functions. Here “Chipset” re-
fers to system level chipset structured by Southbridge & Northbridge; it
determines motherboard’s structure and main functions.
CMOS
Complementary Metal-Oxide Semiconductor, a widely used semicon-
ductor with the characteristic of high speed but low-power-consumption.
CMOS here refers to part of reserved space in on-board CMOS RAM, for
saving date, time, system information and system parameter etc.
COM
Computer-Output Microfilmer. A universal serial communication interface,
usually adopts normative DB9 connector.
DIMM
Dual-Inline-Memory-Module. It’s a small circuit board with memory
chipset, providing 64bit RAM bus width.
DRAM
Dynamic Random Access Memorizer. It’s a normal type of universal mem-
ory often with a transistor and a capacitance to store 1 bit. With the de-
velopment of the technology, more and more types of ORAM with vari-
ous specifications exist in computer application, such as SDRAM, DDR
SDRAM and RDRAM.
IDE
Driver specifications for integrated circuit devices, It is widely used for
connecting HDD / CD-ROM devices.
IrDA
Infrared Data Association for short. Here it refers to infrared transmit in-
terface, to connect infrared transmit devices. This sort of device transmits
data by infrared light-wave without connecting any cables. It has been
developed into a standard now.
