interface
A hardware or software protocol, contained in the electronics
of the tape controller and tape drive that managed the exchange of data
between the drive and computer. The most common interfaces for small
computer systems are AT (IDE) and SCSI.
internal drive A drive mounted inside one of a computer’s drive bays.
Internet A worldwide network of computer servers originally developed
by the federal government as a communication system in the event of
nuclear war or other wide-scale disaster.
intranet A private version of the Internet that provides a cost-effective
way to publish critical information and provide an interactive
communication path for heterogeneous systems.
IP Internet Protocol. A communications protocol which contains a
network address and routes a message to a different network.
J
jumper A tiny connector box that slips over two pins that protrude from
a circuit board. The jumper can be moved to change electrical connectors.
When in place, the jumper connects the pins electrically. Some board
manufacturers use dual in-line package (DIP) switches instead of
jumpers.
K
KB Kilobyte. A unit of measure consisting of 1,024 bytes.
kHz Kilohertz. A measurement of frequency that equals 1000 Hz.
L
LAN Local Area Network. A computer network covering a relatively
small area. A LAN usually is confined to a building or a few nearby
buildings. A LAN can be connected to another LAN over any distance
through telephone lines and radio waves to form a wide area network
(WAN).
LCD Liquid Crystal Display. The technology used by portable computer
and flat-panel displays. The Operator Control Panel on the front of the
SuperLoader is an LCD screen.
Lempel-Ziv Algorithm A data compression technique used in all DLT
tape drives. Named after Abraham Lempel and Jacob Ziv.
library system A system that uses a robotic mechanism to automatically
load and unload tape cartridges into one or more tape drives.
Distinguishable from stackers and autoloaders in their ability to provide
random access to tape cartridges. The DLTstor is a tape library system
offered by Quantum Corporation.
