devices (such as tape drives, hard disks,
CD-ROM players, printers, and scanners)
to computers (servers). Pronounced
“scuzzy”. Variations of the SCSI interface
provide for faster data transmission rates
than standard serial and parallel ports (up
to 160 megabytes per second). The
variations include:
v
Fast/Wide SCSI: Uses a 16-bit bus, and
supports data rates of up to 20 MBps.
v
SCSI-1: Uses an 8-bit bus, and supports
data rates of 4 MBps.
v
SCSI-2: Same as SCSI-1, but uses a
50-pin connector instead of a 25-pin
connector, and supports multiple
devices.
v
Ultra SCSI: Uses an 8- or 16-bit bus,
and supports data rates of 20 or 40
MBps.
v Ultra2 SCSI: Uses an 8- or 16-bit bus
and supports data rates of 40 or 80
MBps.
v
Ultra3 SCSI: Uses a 16-bit bus and
supports data rates of 80 or 160 MBps.
v
Ultra160 SCSI: Uses a 16-bit bus and
supports data rates of 80 or 160 MBps.
