Glossary of Terms
copy files from one node to another interactively or programmatically.
network interprocess communication (NetIPC) A network services (NS) user
service that allows autonomous processes running concurrently at
different nodes to exchange information in a peer-to-peer manner.
network layer Layer three of the Open Systems Interconnection (OSI) network model.
Network layer tasks include determining the routes messages take to get
from one node to another.
network map A diagram of the links, nodes, and networks in a catenet. A network map
should include node information (system type and resources, peripherals,
amount of memory, and services supported) and linked information
(location of coaxial cables, terminators, repeaters, attachment unit
interface (AUI) cables, and media attachment unit (MAUs).
network remote job entry (NRJE) A facility to provide batch systems network
architecture (SNA) communications. SNA NRJE allows users to transmit
large batch jobs and files from an HP 3000 to an IBM mainframe for
processing and to receive output and files from an IBM mainframe.
network services (NS) Network services (NS) software products provide user interface
to the network. They allow batch job submittals, file transfers, virtual
terminal access, and other services.
$NEWPASS Temporary file created automatically, typically during compiling, to which
newly generated compiled code is written. This is a system-defined file and
only one may exist during a single job or session. When this file is closed,
its name changes to $OLDPASS.
node One end of a communications link or a computer system in a network. For
example, if two HP 3000 computers are connected by a DS line, each
system is considered a node.
node manager capability (NM capability) A capability assigned to users allowing
them to control communication subsystems at their node.
node name A string of up to 31 characters, not including control characters or spaces,
that uniquely identifies a node in a network or internetwork.
noise Undesirable signals on a communication channel. Noise can interfere with
or distort data signals.
nonremovable disks Disks that cannot be removed from the disk drive.
nonshareable device capability (ND capability) A capability assigned to accounts
and users allowing account members to own nonshareable devices such as
unspooled printers, serial disks, private volumes (on MPE V/E), and
foreign disks.
nonsystem volumes Volumes that do not need to be mounted for the operating system to
run. Also called mountable volumes. These volumes are equivalent to MPE
V/E private volumes.
NS Common Services A group of network services including network file transfer
(NFT), network interprocess communication (NetIPC), remote process
