most users prefer noninterlaced video adapter resolutions. Abbreviation for kilobyte(s) per second. An instruction and data cache built in to the processor. The Intel Pentium processor 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. Abbreviation for kilobit(s), 1,024 bits. Abbreviation for kilobit(s) per second. Acronym for internetwork packet exchange. 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 processor. 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. 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. A command requiring you to press multiple keys at the same time. For example, you can reboot your computer by pressing the key combination. Abbreviation for kilogram(s), 1,000 grams. Abbreviation for kilohertz, 1,000 hertz. Acronym for local area network. A LAN system is usually confined to the same building or a few nearby buildings, with all equipment linked by wiring dedicated specifically to the LAN. Abbreviation for pound(s). Abbreviation for information technology equipment. Abbreviation for light-emitting diode. An electronic device that lights up when a current is passed through it. 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. 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 processor. Abbreviation for kilo-, indicating 1,000. Abbreviation for kilobyte(s), 1,024 bytes. The device names for the first through third parallel printer ports on your computer are LPT1, LPT2, and LPT3. 8 Dell Precision 610 Mini Tower Systems User's Guide
