SCSI Small Computer System Interface.
SCAM An acronym for SCSI Configured AutoMagically or SCSI Configured
AutoMatically. SCAM is SCSI’s new automatic ID assignment protocol.
SCAM frees SCSI user’s from locating and setting SCSI ID switches and
jumpers. SCAM is the key part of Plug and Play SCSI.
SEL/ Select – Used by an initiator to select a target or by a target to reselect
an initiator.
Single-ended
configuration An electrical signal configuration that uses a single line for each signal,
referenced to a ground path common to the other signal lines. The
advantage of a single-ended configuration is that it uses half the pins,
chips, and board area that differential configurations require. The main
disadvantage of single-ended configurations is that they are vulnerable
to common mode noise. Also, cable lengths are limited.
Synchronous
transmission Transmission in which the sending and receiving devices operate
continuously at the same frequency and are held in a desired phase
relationship by correction devices. For buses, synchronous transmission
is a timing protocol that uses a master clock and has a clock period.
Target An SCSI device that performs an operation requested by an initiator.
Termination The electrical connection at each end of the SCSI bus, composed of a
set of resistors.
s Microsecond.
