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/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.

PS/2
A keyboard & mouse connective interface specification developed by IBM.PS/2 is a DIN
interface with only 6PIN; it also can connect other devices, like modem
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.
