parameter etc.
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
RAM 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.
