provides a central database of information, such as Internet

named buffer --
A
buffer

vi(1)
editor. vi clears unnamed buffers when it
switches files, but the contents of named buffers are
preserved.
netmask --
Determines which part of your network address is used as a network ID and
which part is used as the system, or host, ID. For example, say your network
address is 123.456.789.101 and your network is a Class B network. By default,
on a Class B network, the first two parts of the address, 123.456, identify the
network where your system resides, and the last two parts, 789.101, identify
your specific system within that network. By changing the netmask, you can
change which part of the IP address identifies the network and which identifies
the system.
netname --
A string of printable characters
created by concatenating the name of the operating system,
a user ID, and a domain name.
Netnames are used in DES authentication.
NetWare mode --
A filesystem installed in NetWare mode on a NetWare server only supports
DOS semantics when you access it from the operating system. For
example,
chown(2)
and
chmod(1)
commands cannot be used to
change all file permissions and you cannot use file names that
are longer than the standard 8.3 characters.
NetWare rights --
Attributes associated with a file or folder on a NetWare server. When files and
folders on a NetWare system are used from an SCO® system, NetWare
rights (supervisor, read, write, create, erase, modify, file scan, and access
control) are mapped to UNIX system permissions (read, write, and execute).
network --

perform the actual management operations requested by the network management
station.
non-current --
(programming)
A frame, or other element on display which is
not the element in which the cursor is currently positioned.
non-destructive installation --
An installation where the operating system is replaced but user files remain
untouched. There are two types of nondestructive installations: overlay (where
the same release of the operating system is installed) and upgrade
(where a new release of the operating system replaces an earlier
release).
See also
upgrade installation
and
overlay installation.
network protocols --

should interact within a network to transmit information.
Network Information Center (NIC) --

numbers and domain names.
NIC handle --

Network Information Service (NIS) --
A distributed naming service used

accessible to a computing community.
It provides a uniform, network-wide storage and retrieval method
that is both protocol- and media-independent.
NIS server --
A system that stores a set of NIS maps
that it makes available to network hosts.
