BUS

BUS is a channel for different devices to exchange data in computer system. It is hardware

circuit. BUS here refers to partial lines inside CPU and the main components of system

memory.

Chipset

Chipset is an Integrated set of chips for executing one or more related functions。Here it

refers to a system level chipset structured by Southbridge & Northbridge; Chipset decides the

structure and main functions of motherboard.

CMOS

Complementary Metal-Oxide Semiconductor, which is a widely used semiconductor with

the characteristics of high-speed and low-power. COMS here refer to part of space on-board

CMOS RAM for saving date, time, system information and system parameter, etc.

COM

Cluster Communication Port. A universal serial communication interface, usually adopts

normative DB 9 connector.

Page 41

EMB-7536 User’s Manual

DRAM

Dynamic Random Access Memory. It is a general type of memory for regular computer

which usually store 1 bit with a transistor and a capacitance. With the development of the

technology, more and more types of DRAM with different specifications exist in computer

applications. For example: SDRAM、DDR SDRAM and RDRAM.

LAN

Local Area Network. Network grouped by correlative computers in a small area, generally

in a company or a building. Local area network is buildup by sever, workstation, some

communications links. Terminals can access data and devices anywhere through cables,

which enables users to share costly devices and resource.

LED

Light-Emitting Diode. A semiconductor device that lighted when power supply is connected,

It is often used to indicate information directly, for example, to indicate power on or HDD

working normally.

PnP

Plug-and-Play. It is a specification that allows PC to configure its external devices

automatically and it works independently without the manual operation. To achieve this function,

BIOS should be able to support PnP and a PnP expansion card.

POST

Power On Self Test. While the system is booting, BIOS will keep testing the system which

including RAM, keyboard, hard disk driver to check if all the components are connected directly

and function well.

USB

It is the Universal Serial Bus for short. A hardware interface adapts to low speed

peripherals, and is always used to connect keyboard, mouse etc. One PC can connect

maximum 127 USB devices, providing 12Mbit/s transmit bandwidth USB supports hot swap

and multi- data stream, namely, you can plug USB devices while system is running, system can

auto-detect and makes it work on.
