process by eliminating the bus free phase. When combined with packetization,
reduces command overhead and m aximizes bus use.

(LQ) packet followed by multiple data packets. Minimizes overhead of data
transfers because the target can send one data stream packet followed by
multiple data packets.
receiver The ultimate destination of data transmission; a terminal device
SCSI Small Computer Systems Interface: a processor-independent standard for
system-level interface between a computer and intelligent devices including hard
disks, fl oppy disks, CD-ROM, printers, scanners, etc.
single-ended An electrical signal protocol that transmits information through changes in
voltage. Single-ended SCSI uses standard TTL signal and ground pairs to
transmit information over the SCSI bus.
topology Logical layout of the parts of a computer system or network and their
interconnections.
training pattern SCSI is a parallel bus technology that is dependent on signals being transmitted
on parallel wires simultaneously. At higher speeds, minute differences in wire
lengths and transmission characteristics could cause problems. Training pattern
testing measures these minute differences and compensates for them.
transceiver A transmitter/receiver module.
transfer rate The rate at which bytes or bits are transferred, as in megabytes or gigabits
per second.
