COM
Cluster Communication Port. A universal serial communication interface, usually adopts
normative DB 9 connector.
DIMM
Dual-Inline-Memory-Modules. It is a small circuit board with memory chipset providing 64
bit memory bus width.
DRAM
Dynamic Random Access Memory. It’s 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.
IDE
A specification for integrated circuit device drivers, widely used to connect hard disk drive
interfaces and hard disk / CD-ROM devices.
IrDA
The infrared transmission interface is used to connect the infrared transmission module.
This kind of equipment transmits data through infrared light wave without any cable connection,
and now it has developed into a standard.
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.
