LQWHUQDO￿PLFURSURFHVVRU￿FDFKH

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.

,3;

Acronym for Internetwork Packet eXchange.

,3;￿63;

Acronym for Internetwork Packet eXchange/Sequenced Packet eXchange

,54

Abbreviation for interrupt request. A sig- nal 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 se- rial 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.

,6$

Acronym for Industry-Standard Architec- ture. A 16-bit expansion bus design. The expansion-card connectors in an ISA com- puter are also compatible with 8-bit ISA expansion cards.

,7(

Abbreviation for information technology equipment.

MXPSHU

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.

ORFDO￿EXV

On a computer with local-bus expansion capability, certain peripheral devices (such as the video adapter circuitry) can be designed to run much faster than they would with a traditional expansion bus. Some local-bus designs allow peripherals to run at the same speed and with the same width data path as the computer’s microprocessor.
