SOLTEK SL-85DRS User Manual page 81

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.
RAID (Redundant Array of Independent Disks)
A group of hard disks set up in PC system for data fault tolerance and
better performance. RAID is usually more used in servers than in personal
computers. Different level of RAID stands for different function and
performance:
Level 0 provides data striping or spreading out blocks of files across
multiple disks, and so improvement of performance but no fault
tolerance.
Level 1 provides disk mirroring, and so data backup.
Level 3 provides a dedicated disk for error correction of data, and so
better performance and some fault tolerance.
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.
