native language
A computer user’s spoken or written language, such as Chinese, Dutch, English, French, German, Greek,
Italian, Katakana, Korean, Spanish, Swedish, Turkish, and so on.
Network File System (NFS)
The Network File System (NFS) allows a client node to perform transparent file access over the network.
By using NFS, a client node operates on files residing on a variety of servers and server architectures, and
across a variety of operating systems. File access calls on the client (such as read requests) are converted
to NFS protocol requests and sent to the server system over the network. The server receives the request,
performs the actual file system operation, and sends a response back to the client.
NFS operates in a stateless manner using remote procedure calls (RPC) built on top of an external data
representation (XDR) protocol. The RPC protocol enables version and authentication parameters to be
exchanged for security over the network.
Native Language Support (NLS)
A feature of HP-UX that provides the user with internationalized software and the application programmer
with tools to develop this software.
newline character
The character with an ASCII value of 10 (line feed) used to separate lines of characters. It is represented
by \n in the C language and in various utilities. The terminal driver normally interprets a carriage-
return/line-feed sequence sent by a terminal as a single newline character (but see tty(7) for full details)
NLS
See Native Language Support.
NLSPATH
An environment variable used to indicate the search path for message catalogs (see message catalog).
node name
A string of up to 31 characters, not including control characters or spaces, that uniquely identifies a node on
a Local Area Network (LAN). The node name for each system is set by the
npowerup
command, which
is one of the commands supplied with optional LAN/9000 products. Do not confuse a node name with a
host name, which is a string that uniquely identifies an HP-UX system on a UUCP network. Your node
and host names can be identical, but they are used and set by totally different software. See host name,
LAN/9000 User’s Guide, and LAN/9000 Node Manager’s Guide.
nonspacing characters
Characters, such as a diacritical mark or accents, that are used in combination with other characters to
form composite graphic symbols commonly found in non-English languages.
open file
A file that is currently associated with a file descriptor.
open file description
A record of how a process or a group of processes is accessing a file. Each file descriptor refers to exactly
one open file description, but an open file description can be referred to by more than one file descrip-
tor. The file offset, file status flags, and file access modes are attributes of an open file description.
ordinary file
A type of HP-UX file containing ASCII text (for example, program source), binary data (for example, exe-
cutable code), etc. Ordinary files can be created by the user through I/O redirection, editors, or HP-UX
commands.
orphan process
A child process that is left behind when a parent process terminates for any reason. The
init process
(see init(1M)) inherits (that is, becomes the effective parent of) all orphan processes.
orphaned process group
A process group in which the parent of every member is either itself a member of the group or is not a
member of the group’s session.
