IEEE 802.3 A standard for a
broadcast local area network
published by the Institute for
Electrical and Electronics
Engineers (IEEE). This standard
is used for both the ThinLAN and
ThickLAN implementations of
the LAN
Internet Protocol (IP) A
protocol used to provide routing
between different local networks
in an internetwork, as well as
among nodes in the same local
network. See also IP address.
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.
IP address Internet Protocol
address. An address used by the
Internet Protocol to perform
internet routing. A complete IP
address comprises 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.
L
loopback The routing of
messages from a node back to
itself.
N
network address This can be
either 1) the network portion of
an IP address as opposed to the
node portion, or 2) when referring
to X.25 networks, it is a node’s
X.25 address.
network directory A file
containing information required
for one node to communicate with
other nodes in 1) an internetwork,
2) an X.25 network, or 3) a
network that contains non-HP
nodes. The active network
directory on a node must be
named NSDIR.NET.SYS.
NMDUMP A utility used to
format log and trace files.
