Small Computer Systems Interface (SCSI)
A standard used by computer manufacturers for attaching peripheral
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.
