cache, which is set up as an 8-KB read-only instruction cache and an 8-KB read/write data cache.
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.
ISA
Acronym for Industry-Standard Architecture. A 16-bit expansion bus design. The expansion-card connectors in an ISA
system are also compatible with 8-bit ISA expansion cards.
KB
Abbreviation for kilobyte(s), 1,024 bytes.
Kbit(s)
Abbreviation for kilobit(s), 1,024 bits.
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><Delete> key combination.
kg
Abbreviation for kilogram(s), 1,000 grams.
kHz
Abbreviation for kilohertz, 1,000 hertz.
lb
Abbreviation for pound(s).
LED
Abbreviation for light-emitting diode. An electronic device that lights up when a current is passed through it.
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).
Mb
Abbreviation for megabit.
