- NASD
- See Network Attached Storage Device (NASD).
- National Center for Supercomputing
Applications (NCSA)
- The National Center for Supercomputing Applications (NCSA),
located at the University of Illinois at Urbana-Champaign, is a
high-performance computing and communications facility and research
center designed to serve the U.S. computational science and
engineering community.
- NCSA
- See National Center for Supercomputing Applications
(NCSA).
- NDMP
- See Network Data Management Protocol (NDMP).
- negative caching
- Some DNS servers keep the answer "no such
host or domain" cached to minimize response time to the
resolver.
- NetInfo
- A hierarchical collection of databases used by NEXTSTEP computers
for maintaining administrative information such as user accounts,
host entries, printer information, and file
system mounting data. The hierarchy consists of domains, or levels.
- netnews
- See USENET news.
- network
- A group of machines that share information and resources. A group of
smaller networks or subnetworks. See also
internet, Local Area
Network (LAN), subnet,
Wide Area Network (WAN).
- Network Access Point (NAP)
- Telecommunications term for the location where a call (data or voice)
enters the telecommunications network.
- network address
- An IP address represented by a four-byte
field written as byte1.byte2.byte3.byte4, where each byte is
an ASCII numeric representation (0 through
255). See also host,
Internet, network,
subnet.
- network administrator
- See system administrator.
- Network Attached Storage (NAS)
- Storage (usually disks but possibly tapes or memory) attached
to and distributed (shared) over a network. Usually the environment
of a NAS is many computers sharing a lot of data; the typical
bottleneck in performance is the file manager or object store.
A common example is NFS over a LAN.
- Network Attached Storage Device (NAS)
- Developed at CMU, a more intelligent
peripheral (disk or tape drive) that does its own file management.
The drives enforce (but do not define) a security policy. Clients
have an NFS-like interface and access model.
- Network Data Management Protocol (NDMP)
- An open protocol for network-based backup of data.
- Network File System (NFS)
- Allows file systems from one
machine to be shared transparently across a network by other
machines. Originally defined in
RFC 1094 (v2) and
RFC 1813 (v2).
- Network Information Center (NIC)
- The Internet's Network Information Center is responsible for controlling
domain names across the entire Internet.
- Network Information Service (NIS)
- Formerly known as Yellow Pages (YP). A service used for the
administration of network-wide databases within a specified
domain. The databases, called maps, are
provided by servers
(master servers which control the domain
and are client-writable for changes, and/or
slave servers which are
client-read-only) to participating
hosts (clients) within a specified domain.
- Network Monitoring System (NMS)
- An application to notify front-line support personnel about problems
with applications running on remote machines (such as the trading floor
machines).
- Network News Transfer Protocol (NNTP)
- A client/server
protocol for exchanging and reading
USENET news articles.
- Network Time Protocol (NTP)
- A protocol for synchronizing the clocks on all the hosts on a
network or subnet to that of a single master time-keeper. Defined
in RFC 1119 (v2)
and RFC 1305
(v3).
- Network-to-Network Interface (NNI)
- The connection on telecommunications equipment between two disparate
telecommunications networks.
- news
- See USENET news.
- NeXTMail
- The application for reading and sending mail on NeXT computers. Can
include attachments in messages using drag-and-drop. See also
attachment, Multipurpose
Internet Mail Extensions (MIME), mail.

- See Network File System (NFS).
- NIC
- See Network Information Center (NIC).
- NIS
- See Network Information Service (NIS).
- NIS+
- An extension to the Network Information Service (NIS)
including hierarchical domains, incremental updates to other servers,
multiple indices to database tables, and built-in security. Requires the
Solaris operating system.

a network or subnet to that of a single master time-keeper.

- notice
- A message concerning some operation or change in the distributed system.
- Novell Link State Protocol (NLSP)
- The equivalent of Open Shortest Path First
(OSPF) for IPX RIP
and SAP services. Much more efficient in its use of bandwidth and improved
stability.
