installed in a 3.5-inch or 5.25-inch carrier, whether it is a storage device
or power supply.
SCSI
Small computer system interface. (1) An ANSI interface standard
defining the physical and electrical parameters of a parallel I/O bus
used to connect initiators to devices. (2) a processor-independent
standard protocol for system-level interfacing between a computer and
intelligent devices including hard drives, floppy disks, CD-ROMs,
printers, scanners, and others.
SCSI-A cable
A 50-conductor (25 twisted-pair) cable generally used for single-ended,
SCSI-bus connections.
SCSI bus signal
converter
Sometimes referred to as an adapter. (1) A device used to interface
between the subsystem and a peripheral device unable to be mounted
directly into the SBB shelf of the subsystem. (2) a device used to
connect a differential SCSI bus to a single-ended SCSI bus. (3) A
device used to extend the length of a differential or single-ended SCSI
bus. See also I/O module.
SCSI device
(1) A host computer adapter, a peripheral controller, or an intelligent
peripheral that can be attached to the SCSI bus. (2) Any physical unit
that can communicate on a SCSI bus.
SCSI device ID number
A bit-significant representation of the SCSI address referring to one of
the signal lines, numbered 0 through 7 for an 8-bit bus, or 0 through 15
for a 16-bit bus. See also target ID number.
SCSI ID number
The representation of the SCSI address that refers to one of the signal
lines numbered 0 through 15.
SCSI-P cable
A 68-conductor (34 twisted-pair) cable generally used for differential
bus connections.
SCSI port
(1) Software: The channel controlling communications to and from a
specific SCSI bus in the system. (2) Hardware: The name of the logical
socket at the back of the system unit to which a SCSI device is
connected.
serial transmission
A method transmission in which each bit of information is sent
sequentially on a single channel rather than simultaneously as in
parallel transmission.
