full duplex (n) A communications system in which there is a capability for 2-way
transmission and acceptance between two sites at the same time.
full duplex (adj) Pertaining to a communications method in which data can be
transmitted and received at the same time.
FWD SCSI A fast, wide, differential SCSI bus with a maximum 16-bit data transfer
rate of 20 MB/s. See also SCSI and FD SCSI.
GBIC Gigabit Interface Converter. GBICs convert electrical signals to optical
signals (and vice-versa.) They are inserted into the ports of the Fibre
Channel switch and hold the Fibre Channel cables.
GLM Gigabit link module
giga A prefix indicating a billion (10
9
) units, as in gigabaud or gigabyte.
gigabaud An encoded bit transmission rate of one billion (10
9
) bits per second.
gigabyte A value normally associated with a disk drives storage capacity,
meaning a billion (10
9
) bytes. The decimal value 1024 is usually used
for one thousand.
half-duplex (adj) Pertaining to a communications system in which data can be either
transmitted or received but only in one direction at one time.
hard address The AL_PA which an NL_Port attempts to acquire during loop
initialization.
heterogeneous
host support
Also called noncooperating host support.
HIPPI–FC Fibre Channel over HIPPI
host The primary or controlling computer to which a storage subsystem is
attached.
host adapter A device that connects a host system to a SCSI bus. The host adapter
usually performs the lowest layers of the SCSI protocol. This function
may be logically and physically integrated into the host system.
HBA Host bus adapter
