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.
