Abbreviation 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 system (COM1) is assigned to IRQ4 by default. Two
devices can share the same IRQ assignment, but you cannot operate both devices simultaneously.
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.
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.
key combination
A command requiring you to press multiple keys at the same time. For example, you can reboot your system by pressing the <Ctrl><Alt><Del> key
combination.
kg
Abbreviation for kilogram(s), 1,000 grams.

Linux
A version of UNIX® that runs on a variety of hardware systems. Linux is open source software, which is freely available; however, the full distribution of Linux
along with technical support and training are available for a fee from vendors such as Red Hat Software (www.redhat.com).
local bus
On a system 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
system's microprocessor.
m
Abbreviation for meter(s).
mA
Abbreviation for milliampere(s).
