APPENDIX
PC-1600 or PC-2100 DDR SDRAM
PC-1600 DDR SDRAM with a 64-bit data bus doubles the data transfer
rate of PC100 SDRAM and hence provides data transfer bandwidth up
to 100x64/8x2=1600MB/s. PC2100 DDR SDRAM doubles the data
transfer rate of PC-133 and hence provides data transfer bandwidth up
to 133x64/8x2=2100MB/s.
PCI (Peripheral Component Interface) Bus
A high speed data channel for the internal connection of peripheral devices
and the computer system through a PCI expansion card.
PnP (Plug and Play)
The PnP specification suggests a standard register interface for both BIOS
and operating system (such as Windows 95). These registers are used by
BIOS and operating system to configure system resource and prevent
any conflicts. PnP BIOS or operating system will automatically allocate
the IRQ/DMA/Memory. Currently, almost all the PCI cards and most
ISA cards are already PnP compliant.
POST (Power-On Self Test)
The BIOS self-test procedure after power-on. It is generally the first or
the second program shown on your monitor screen during system boot.
RAS (Row Address Strobe)
RAS is a technology that DRAM writes and reads to the Row addresses,
while a CAS (Column Address Strobe) signal is used to validate the
column address. The signals are generally sent CAS before RAS.
(in Network field, RAS stands for Remote Access Services).
RDRAM (Rambus DRAM)
Rambus DRAM is a memory technology that uses large burst mode data
transfer of up to 1.6GHz. It is import to know that RDRAM technology
helps set up a system level improvement, not just a component upgrade.
RIMM (Rambus Inline Memory Module)
RIMM is built with a 184-pin architecture module that supports RDRAM
memory technology. A RIMM memory module may contain up to
maximum of 16 RDRAM devices.
