NADN (Nearest Active Downstream Neighbor):
The computer being passed a token is the nearest active downstream neighbor.NAP: Network Access Point
The entry point to one of the several large capacity circuits that transport data across the Internet.Narrowband - Voice Grade:
A low-capacity communications Circuit / path. It usually implies a speed of 56Kbps or less. (Contrast with Wideband and Broadband.Native capacity:
How much data any given medium can store without benefit of compression. Various compression techniques allow data beyond native capacity to be recorded.Native file encryption:
A technology introduced into the NTFS file system that allows files and directories to be selectively scrambled for local storage.NAUN (Nearest Active Up-stream Neighbor):
The computer that passes a token to the next computer on the logical ring is called the nearest active upstream neighbor.NC Codes - Network Channel Codes:
Industry standard codes that define the type of service being provided at each end of a circuit.NDM - See Network Data Move. NDS:
Stands for Novell Directory Services. It is the logical, hierarchical directory tree used to manage users and devices on a Novell network. NDS became the structure for Novell networks with the release of NetWare 4.NetBEUI: NetBIOS Extended User Interface
An early Microsoft networking protocol. A simple but fast LAN protocol stack designed for small networks. NetBEUI is a non-routable protocol and was designed as an extension of Microsoft and IBM's NetBIOS protocol.NetBIOS - Network Basic Input/Output System:
This system provides a Session layer interface between network applications running on a PC and the underlying protocol software of the Transport and Network layers on the ODI model. Normally a LAN protocol.Network Access layer (DOD):
This layer is equivalent to the Data Link layer of the 051 model and consists of the protocols that take the packets from the Internet layer and package them in an appropriate frame type.Network Address Translation (NAT):
The ability to hide a group of computers using IP addresses behind one or more IF addresses. NAT is often used to hide friendly networks behind a proxy server. See also proxy servernetwork architecture:
The defining strategy for how computers on the network access the network media. The network architecture will also play some part in the network topology deployed on the network. Examples of network architectures are Ethernet and token ring.Network client:
A piece of software running on a computer that provides network access for the computer and all applications running on that computer.Network Data Mover - NDM:
File transmission protocol software.Network Database Updates:
Process for defining network configuration, valid access/use, alternate routing tables, etc.network File System (NFS):
A virtual file system developed by Sun Microsystems that allows Linux computers to share files on the network.network interface card (NIC):
A peripheral device containing a transceiver (a transmitter and receiver) that is able to convert data from parallel to serial, and vice versa. A NIC is the computer's connection to the network media.Network layer (OSI model):
Responsible for the addressing of packets and their routing on the network.Network Monitor:
A Windows Server utility that allows you to monitor and track network performance and traffic.network operating system (NOS):
Software that imparts special server capabilities to a computer A server running an NOS can authenticate users to the network and share network resources.network share:
A drive or folder on a server that is made available to users on the network. Shares cannot consist of individual files.Network Surveillance:
Equipment, people, systems and procedures that monitor network activity and react to unusual situations.network:
A group of connected computers that can share resources. Networks can be as small as two computers connected in a peer-to-peer arrangement or as large as global networks, such as the Internet that use a number of different WAN connectivity strategies, Including satellite technology. A system of interrelated elements that are interconnected in a dedicated or switched linkage to provide local or remote communication (of voice, video, data, etc.) and to facilitate the exchange of information between end users with common interests. The set of switches, circuits, trunks and software that make up a telecommunications facility.Networked Computing Technologies:
Hardware, software and architectural approaches for distributing computer applications across interconnected computers.newsgroup:
An electronic bulletin board provided by a news server, such as those provided by Usenet. Information on news servers is broken into categories. Each subject area is called a newsgroup.NFS - Network File System:
This system is a protocol developed to use IP and allow a set of computers to access each other's file systems as if they were on the local host.Nibble mode:
Sends the 8-bit byte of data to the printer in two cycles, each of which carries four bits, or a nibble of data. This method requires software support and more overhead on the part of the host computer. Even slower than compatibility mode, ranging from 50KB to 65KB/s.Nibble:
Any combination of four zeros or ones.NIC: Network Interface Card NiCad: Nickel Cadmium
A type of rechargeable battery.NIFS:
Stands for New Technology File System. NTFS is a file system available on computers running Windows NT, 2000, and XP that supports the spanning of large volumes and uses transaction logs, making it easier to recover data on a failed disk. NTFS is an improvement over the FAT file system that was originally developed for the DOS/Windows environment. See also FAT.Ni-MH: Nickel Metal Hydride
A type of rechargeable battery.NLA: Network Location Awareness
A feature in XP that automatically configures a computer system to the network or subnet to which the device is attached.NLB: Network Load Balancing NLX: New Low-profile Extended
One of several form factors whose objective was to keep the system as small as possible.NMI: Non-Maskable Interrupt
Any software or hardware induced interrupt that requires instantaneous attention from the CPU.node:
A client computer, server, or other device (such as a router) that is connected to the network. Generic term used to refer to an entity that accesses a network.Node:
Any one of several addressable types of allocated space on a hard disk that can contain the data that makes up a file.Northbridge:
The faster of the ICs in the chipset that is responsible for managing RAM, cache, and AGP functions.Novell Directory Services (NDS):
The tree-like hierarchical structure that contains objects such as users and groups on a NetWare network. Also see eDirectory.NTFS: New Technology File System NTI - Northern Telecom Incorporated:
Manufacturer of a wide variety of telecommunications related products.NTN - National Telecommunications Network:
A consortium of LDDS WorldCom, Litel, CNI, SouthernNet and Microtel that banded together in 1985 to form a national telecommunications network.NTWS: NT Workstation NWlink:
Microsoft's clone of the IPX/SPX protocol stack. See also IPX/SPX (Internetwork Packet Exchange/Sequenced Packet Exchange).
