REFERENCE INFORMATION
Interrupt Request (IRQ)
A prioritized signal line used by hardware devices to interrupt the processor and request
processing attention. Each hardware device generally requires its own IRQ address--a number
from 0 to 15 (0 to F in
hexadecimal).
IP address
A number that identifies the location of a network and a local computer on a network. It is
composed of four octets separated by decimals, such as 127.17.5.12. IP addresses are used
exclusively with the
TCP/IP network protocols.
IPMB
Intelligent Platform Management Bus. Name for the architecture, protocol, and implementation of
a special bus that interconnects the baseboard and chassis electronics and provides a
communications media for system platform management information.
IPMI
Intelligent Platform Management Interface. A specification developed to define the message and
system interface for management-enabled hardware. IPMI contains monitoring and recovery
features that allow management of the hardware regardless of whether the machine is turned on
or not, or what state the OS may be in.
ISA
Industry Standard Architecture. The original bus standard used in IBM and compatible computers.
ISA was later superseded by more technologically advanced bus architectures, such as
EISA,
MCA, PCI, and SCSI.
J
JBOD
Just a Bunch Of Disks. Used to refer to hard disks that aren't configured according to RAID -- a
subsystem of disk drives that improves performance and fault tolerance.
K
None
L
LIF socket
Low Insertion Force socket. An older socket type used on early motherboards for processors and
other chips. Unlike its successor, the
ZIF socket, you must use considerable force when inserting
a chip into a LIF socket, and a special tool or screwdriver is generally required to remove a chip
from a LIF socket.
LPT1
First parallel printer port (Line Printer 1). Because parallel ports are typically used for connecting
printers to a computer, the parallel port names LPT1 and LPT2 were named after the early "line
printers" that connected to them (line printer 1, line printer 2, and so forth).
M
MAC address
