internet communication
Communication that occurs
between networks.
internet hop count The
number of full gateways plus the
numberof gateway-halflinks that
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.
TheInternetProtocolcorresponds
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.
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

intrinsic A system routine
accessible by user programs. It
provides an interface to operating
system resources and functions.
Intrinsics perform common tasks
such as file access and device
control.
IP See internet protocol.
IP address Internet Protocol
address. An address used by the
Internet Protocol to perform
internet routing. A complete IP
address consists of a network
portion and a node portion. The
network portion of the IP address
identifies a network,and the node
portion identifies a node within
the network.
IP router A node in an IP
network that connects two or
more networks and provides
address mapping between them.
The router selects messages from
incoming buffers and places them
into the appropriate outgoing
message queues.
IP subnet mask. See subnet
