a silicon crystal or other semiconductor
material. The small size of these circuits
allows high speed, low power dissipation,
and reduced manufacturing cost
compared with board-level integration.
Also known as a
chip
.
integrated drive electronics (IDE)
A disk drive interface based on the 16-bit
IBM personal computer Industry Standard
Architecture (ISA) in which the controller
electronics reside on the drive itself,
eliminating the need for a separate
adapter card. Also known as an
Advanced Technology Attachment
Interface (ATA).
Internet Protocol (IP)
A protocol that routes data through a
network or interconnected networks. IP
acts as an intermediary between the
higher protocol layers and the physical
network.
Internet Protocol (IP) address
The unique 32-bit address that specifies
the location of each device or workstation
on the Internet. For example, 9.67.97.103
is an IP address.
interrupt request (IRQ)
A type of input found on many
processors that causes the processor to
suspend normal processing temporarily
and start running an interrupt handler
routine. Some processors have several
interrupt request inputs that allow
different priority interrupts.

Java Runtime Environment (JRE)
A subset of the Java Development Kit
(JDK) for end users and developers who
want to redistribute the Java Runtime
Environment (JRE). The JRE consists of
the Java virtual machine, the Java Core
Classes, and supporting files.
JRE

.
label
A discovered or user entered property
value that is displayed underneath each
device in the Physical and Data Path
maps.
LAN
See
local area network
.
LBA
See
logical block address
.
local area network (LAN)
A computer network located on a user's
premises within a limited geographic
area.
logical block address (LBA)
The address of a logical block. Logical
block addresses are typically used in
hosts' I/O commands. The SCSI disk
command protocol, for example, uses
logical block addresses.
logical partition (LPAR)
A subset of a single system that contains
resources (processors, memory, and
input/output devices). A logical partition
operates as an independent system. If
hardware requirements are met, multiple
logical partitions can exist within a
system.
A fixed-size portion of a logical volume.
A logical partition is the same size as the
physical partitions in its array. Unless the
logical volume of which it is a part is
mirrored, each logical partition
corresponds to, and its contents are stored
on, a single physical partition.
One to three physical partitions (copies).
The number of logical partitions within a
logical volume is variable.
logical unit number (LUN)
An identifier used on a small computer
system interface (SCSI) bus to distinguish
among up to eight devices (logical units)
with the same SCSI ID.
loop address
The unique ID of a node in fibre-channel
loop topology sometimes referred to as a
loop ID.
loop group
A collection of storage area network
(SAN) devices that are interconnected
serially in a single loop circuit.
loop port
A node port (N_port) or fabric port
(F_port) that supports arbitrated loop
functions associated with an arbitrated
loop topology.
