not stripe. RAID level 1 also allows for faster access time and fault-tolerance, since
either hard drive can be read at the same time. RAID level 0+1 is striping and
mirroring, providing fault-tolerance, striping, and faster access all at the same time.
RAIDIOS: RAID I/O Steering (Intel)
RAM (Random Access Memory): technically refers to a type of memory where any
byte can be accessed without touching the adjacent data and is often referred to the
system’s main memory. This memory is available to any program running on the
computer.
ROM (Read-Only Memory): a storage chip which contains the BIOS; the basic
instructions required to boot the computer and start up the operating system.
SDRAM (Synchronous Dynamic RAM): called as such because it can keep two
sets of memory addresses open simultaneously. By transferring data alternately from
one set of addresses and then the other, SDRAM cuts down on the delays associated
with non-synchronous RAM, which must close one address bank before opening the
next.
Serial port: called as such because it transmits the eight bits of a byte of data along
one wire, and receives data on another single wire (that is, the data is transmitted in
serial form, one bit after another).
SCSI Interrupt Steering Logic (SISL): Architecture that allows a RAID controller,
such as AcceleRAID 150, 200 or 250, to implement RAID on a system board-
embedded SCSI bus or a set of SCSI busses. SISL: SCSI Interrupt Steering Logic
(LSI) (only on LSI SCSI boards)
Sleep/Suspend mode: in this mode, all devices except the CPU shut down.
SDRAM (Static RAM):
unlike DRAM, this type of RAM does not need to be refreshed
in order to prevent data loss. Thus, it is faster and more expensive.
SLI (Scalable Link Interface) : NVIDIA SLI
technology
links two
graphics cards
together to provide scalability and increased performance. NVIDIA SLI takes
advantage of the increased
bandwidth
of the
PCI Express
bus architecture, and
features
hardware
and
software
innovations within NVIDIA
GPU
s (graphics
processing units) and NVIDIA MCPs (media and
communications
processors).
Depending on the
application
, NVIDIA SLI can deliver as much as two times the
performance of a single GPU configuration.
Standby mode: in this mode, the video and hard drives shut down; all other devices
continue to operate normally.
UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also called
UltraATA. Without a proper UltraDMA controller, your system cannot take advantage
of higher data transfer rates of the new UltraDMA/UltraATA hard drives.
