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)
SIMM (Single In-line Memory Module): formally the most common form of
RAM for motherboards. They must be installed in pairs, and do not have the
carrying capacity or the speed of DIMM modules.
Sleep/Suspend mode: in this mode, all devices except the CPU shut down.
SRAM (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.
SSI (Server System Infrastructure): an industry initiative intended to provide
ready-to-use design specifications for common server hardware elements
(chassis, power supplies, and racks) to promote and support server industry
growth.
Standby mode: in this mode, the video and hard drives shut down; all other
devices continue to operate normally.
Striping: see RAID
UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also
called UltraATA. Without proper UltraDMA controller, your system cannot take
advantage of higher data transfer rates of the new UltraDMA/UltraATA hard
drives.
USB (Universal Serial Bus): a versatile port. This one port type can function
as a serial, parallel, mouse, keyboard or joystick port. It is fast enough to
support video transfer, and is capable of supporting up to 127 daisy-chained
peripheral devices.
VGA (Video Graphics Array): the PC video display standard
V-SYNC: controls the vertical scanning properties of the monitor.
ZCR: Zero Channel RAID. PCI card that allows a RAID card to use the
onboard SCSI chip, thus lowering cost of RAID solution
ZIF Socket (Zero Insertion Force socket): these sockets make it possible to
insert CPUs without damaging the sensitive CPU pins. The CPU is lightly
placed in an open ZIF socket, and a lever is pulled down. This shift the
processor over and down, guiding into the board and locking it into place.
