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 Address
Abbreviation for Internet Protocol address. See TCP/IP.
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.
