Glossary
half-duplex
A method of two-way
communication over a single physical
link. Only one party can transmit at a
time, the other party remaining silent
to avoid interference. To provide two-
way communication, each party takes
it in turns to transmit. This is the
method of communication most often
used between a PC and a network
Hub.
hub
A general term frequently used
instead of repeater.
IEEE
Institute of Electrical and
Electronics Engineers. Founded in
1963, the IEEE is an organization
composed of scientists, engineers,
and students. The IEEE is best known
for its work in establishing standards
for the computer and electronics
industry.
IEEE 802
A committee of the
Institute of Electrical and Electronics
Engineers (IEEE). IEEE 802 was
organized to establish standards for
the physical and electrical
connections used in LANs.
IEEE 802.3
A subcommittee of the
Institute of Electrical and Electronics
Engineers (IEEE) 802 committee.
IEEE 802.3 was organized to establish
standards for Ethernet, a 10-Mbps
baseband LAN.
IEEE 802.12
A subcommittee of
the Institute of Electrical and
Electronics Engineers (IEEE) 802
committee. IEEE 802.12 was
organized to establish standards for
demand priority LANs.
interrupt
A signal that suspends a
program temporarily while
transferring control to the operating
system when input or output is
required. Interrupts are given priority
levels such that higher priority
interrupts are processed first.
I/O
Input/Output.
I/O Mapped
The NIC registers are
located in the I/O address space.
I/O Port or I/O Address
An
addressable location on the Intel 386
microprocessor to and from which
hardware control information can be
written and read.
IPX
Internet Packet Exchange. IPX
is Novell NetWare's native transport
protocol. It is used to transfer data
between server and/or client
programs running on different

Interrupt Request. An IRQ is a

interrupt a program for an I/O task.
Each hardware device raises
interrupts on a predetermined IRQ
(numbered 0 through 15). The
microprocessor associates specific
interrupts with different interrupt
service routines (ISR).
ISA

the bus used on the AT is often
