N

nail --
To cause a window to remain in the same place on the screen when you change the area of the workspace that you are viewing. A nailed window appears to travel around with you as you move from place to place within your workspace.

named key --
(programming) A keyboard key which has a name indicating the function it performs. For example, <Tab>, <Del>, or <Enter>.

name server --
A program running on the network that provides a central database of information, such as Internet addresses and the names of hosts on which people receive mail.

named buffer --
A buffer used to copy text between files in the 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 --
A group of computers that are linked together and can communicate with each other.

Network Address --
A number that identifies your network and the specific machine on that network. Each computer on a network must have a unique network address. See also Internet Protocol (IP) address.

network client --
(programming) A process that makes remote procedure calls to services.

network management station --
A host running a network management protocol (SNMP) and network mangement applications which monitor and control network devices such as routers, gateways, hosts, and terminal servers. These devices run SNMP agent and/or SMUX peer daemons which 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 --
Sets of rules that explain how software and hardware should interact within a network to transmit information.

Network Information Center (NIC) --
A service that administers IP network numbers and domain names.

NIC handle --
A unique NIC database identifier assigned to a network's administrator and technical contact.

Network Information Service (NIS) --
A distributed naming service used to identify and locate objects and resources 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.

node --
1. A single computer in a network. See also node name. 2. A web page. The text identified by a base URL. See also URL.

node name --
A character string that identifies a single computer in a network. The node name can contain up to eight characters; it resides in the NODE parameter.

normalize --
To restore an iconified window to its ``normal'' (original) appearance. See also iconify.

NTP packet --
A message sent over the network that conforms to the Network Time Protocol format. This format includes space for recording the current time. See also poll.

null device --
A device that always yields end-of-file on reading and discards all data on writing.

null pointer --
(programming) In the C language, a null pointer is a C pointer with a value of 0.
