Glossary 201
IHV
Acronym for independent hardware vendor. IHVs often
develop their own MIBs for components that
they manufacture.
interlacing
A technique for increasing video resolution by only
updating alternate horizontal lines on the screen.
Because interlacing can result in noticeable screen flicker,
most users prefer noninterlaced video adapter resolutions.
internal microprocessor cache
An instruction and data cache built in to the
microprocessor. The Intel Pentium microprocessor
includes a 16-KB internal cache, which is set up as an
8-KB read-only instruction cache and an 8-KB
read/write data cache.
IP
The Internet Protocol (IP) is the method or protocol
by which data is sent from one computer to another on
the Internet. Each computer (known as a host) on the
Internet has at least one IP address that uniquely
identifies it from all other computers on the Internet.
IPMI
Abbreviation for Intelligent Platform Management
Interface, which is an industry standard for management
of peripherals used in enterprise computers based on
Intel architecture. The key characteristic of IPMI is
that inventory, monitoring, logging, and recovery
control functions are available independent of the
main processors, BIOS, and operating system.
IPX
Acronym for internetwork packet exchange.
IRQ
Abbreviation for interrupt request. A signal that data
is about to be sent to or received by a peripheral device
travels by an IRQ line to the microprocessor. Each
peripheral connection must be assigned an IRQ
number. For example, the first serial port in your
computer (COM1) is assigned to IRQ4 by default.
Two devices can share the same IRQ assignment, but
you cannot operate both devices simultaneously.
ISA
Acronym for Industry-Standard Architecture. A 16-bit
expansion bus design. The expansion-card connectors
in an ISA computer are also compatible with 8-bit ISA
expansion cards.
ITE
Abbreviation for information technology equipment.
jumper
Jumpers are small blocks on a circuit board with two or
more pins emerging from them. Plastic plugs
containing a wire fit down over the pins. The wire
connects the pins and creates a circuit. Jumpers provide
a simple and reversible method of changing the
circuitry in a printed circuit board.
JVM
Acronym for Java virtual machine.
K
Abbreviation for kilo-, indicating 1,000.
KB
Abbreviation for kilobyte(s), 1,024 bytes.
KB/sec
Abbreviation for kilobyte(s) per second.
Kbit(s)
Abbreviation for kilobit(s), 1,024 bits.
Kbit(s)/sec
Abbreviation for kilobit(s) per second.
Kerberos
A network authentication protocol that is designed to
provide strong authentication for client/server
applications by using secret-key cryptography.
key combination
A command requiring you to press multiple keys at the
same time. For example, you can reboot your computer
by pressing the <Ctrl><Alt><Del> key combination.
