COM
Computer-Output Microfilmer. A universal serial communication interface, usually adopts
normative OB 9 connector.
DIMM: Dual Inline Memory Module. It
’
s a small circuit board with memory chipset, providing
64bit bus width.
DRAM
Dynamic Random Access Memorizer. It
’
s a normal type of memory often with a transistor
and a capacitance to store 1 bit. With the development of the technology, more and more types
and specification of ORAM exist in computer application. Now: SDRAM, DDR SDRAM and
RDRAM are generally used.
IDE: Driver specification for integrated device electronics, for connecting HDD/CD-ROM
device.
IRDA
Infrared Data Association for short, here means infrared transmit interface, to connect infrared
transmit devices. This sort of device transmits data by infrared light-wave without connecting
any cables .It have been developed a standard now.
LAN
Network interface. 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, as a rule. Terminals can access data and devices anywhere through
cables, so, many users can share costly device and resource.
LED
Light-Emitting Diode. a semiconductor device that shines when power supply is connected,
often use to denote info lightly, for example, to denote power on or HDD work normally.
LPT: line print terminal. The denomination reserved by DOS, is used to denote universal
parallel interface, and connect printer in a general way.
