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 key combination. Glossary 201
