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.
