Small Computer Systems Interface (SCSI)

A standard that is 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 320 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.

v

Ultra320 SCSI: Uses a 16-bit bus and supports data rates of 320 MBps.
