Glossary
IEEE 802.3 multicast address
A hexadecimal number that
identifies a set of nodes. This
address is used for multicast
delivery.
IEEE 802.3 nodal address A
unique hexadecimal number that
identifies a node on an
IEEE 802.3 LAN.
IEEE 802.5 A standard for a
token ring network published by
the Institute for Electrical and
Electronics Engineers (IEEE).
This standard is used for the
Token Ring 3000/iX Network
Link.
initialization string Asequence
of control characters used to
initialize a terminal, printer, or
plotter when a connection is
established from a host on the
network.
interactive communications
Processing that allows users to
enter commands and data at the
terminal and receive an
immediate response.
internet communication
Communication that occurs
between networks.
internet hop count The
number of full gateways plus the
numberof gateway-halflinksthat
a packet must pass through in
moving from source node to
destination.
Internet Protocol A protocol
used to provide routing between
different local networks in an
internetwork, as well as among
nodes in the same local network.
TheInternetProtocol corresponds
to layer 3, the network layer, of
the OSI model. See also IP
address.
internet routing Internet
routing involves all the processes
required to route a packet from a
node on one network to a
destination node on another
network.
internetwork Two or more
networks joined by gateways,
bridges, or routers.
intranet communication
Communication that occurs
between nodes in a single
network.
intranet hop count The
number of intermediate nodes
that lie between a source and
destination node on the same
point-to-point network.
intranet routing Intranet
routing involves all the processes
required to route a packet from
one node in a network to another
node in the same network.
intrinsic System routine
accessible by user programs
which provides an interface to
operating system resources and
functions. Intrinsics perform
common tasks such as file access
and device control.
