NCP. A packet-based protocol that allows a client to send requests to and receive replies from a server.

See NDS.

The former name of NDS.

NLM. A program that runs on the NetWare OS. Once loaded, an NLM becomes part of the network OS. An NLM can be dynamically loaded and unloaded. Types of NLM programs include disk drivers (.dsk extension), LAN drivers (.lan extension), management utilities and server applications modules (.nlm extension), and name space support (.nam extension).

A partition created on each network hard disk, from which NetWare volumes are created.

Note that NetWare disk partitions are not related to NDS partitions. Disk partitions are subdivisions of a hard disk. An NDS partition is a subtree within the NDS tree.

NWPA (a.k.a NPA). An extension of Media Manager (a database built into NetWare for managing storage devices and media). NWPA separates NetWare driver support into two components; a HAM and a CDM. The HAM drives the host adapter hardware. The CDM drives storage devices or autochangers attached to a host adapter bus.

Software that allows clients to communicate with NetWare servers.

A computer that runs NetWare OS software.

A Novell information service on the Internet, CompuServe*, and the Microsoft Network* (MSN) that provides 24-hour online access to technical, corporate, and product information, and connects users with others who use Novell products. The service is updated daily and features downloadable files, patches and drivers, Technical Information Documents (TIDs), message boards, product lists, press releases, and a calendar of events.

A system of interconnected, individually controlled computers and peripherals, and the hardware and software used to connect them.

See administrator.

NFS. A distributed file system developed by Sun Microsystems* that allows a set of computers to access each other's files cooperatively in a transparent manner.

NIC. A circuit board that provides the interface between software and hardware in order to facilitate network communication. For example, it allows workstations to communicate with each other or with the server, or allows a printer to communicate with the server.

The process of ensuring reliability and availability of a network, as well as timely transmission and routing of data. Network management can be performed by dedicated devices or programmed general-purpose devices.

NNTP. The basic Internet protocol used to exchange network news articles between multiple news servers and between news servers and newsreaders.

In a TCP/IP network, the number of the network. The network number can be specified with or without trailing zeros. For example, the addresses 130.57 and 130.57.0.0 denote the same IP network.

In an IPX network, a number that uniquely identifies a network cable segment; usually referred to as the IPX external network number.

A group of jobs waiting to be processed. A job contains data that is only interpreted by the job creator and the job server.

Network File System. A distributed file system developed by Sun Microsystems* that allows a set of computers to access each other's files cooperatively in a transparent manner.

Network Interface Card. A circuit board that provides the interface between software and hardware in order to facilitate network communication. For example, it allows workstations to communicate with each other or with the server, or allows a printer to communicate with the server.

Novell International Cryptographic Infrastructure.

NetWare Loadable Module. A program that runs on the NetWare OS. Once loaded, an NLM becomes part of the network OS. An NLM can be dynamically loaded and unloaded. Types of NLM programs include disk drivers (.dsk extension), LAN drivers (.lan extension), management utilities and server applications modules (.nlm extension), and name space support (.nam extension).

Data items that have only one value for the entire NLM. The data items are global to all the thread groups and threads in the NLM. Any changes made to the values of NLM global data items affect all the thread groups and threads in the NLM.

Novell Licensing Services. A distributed, enterprise network service that enables administrators to monitor and control the use of licensed applications on the network. NLS also provides a basic license metering tools and libraries that export licensing service functionality to developers of other licensing systems.

Novell Modular Authentication Service. A flexible and expandable login and authentication framework that provides developers the means to integrate multiple authentication services into NDS systems.

Network News Transfer Protocol. The basic Internet protocol used to exchange network news articles between multiple news servers and between news servers and newsreaders.

An addressable entity on a network. This term sometimes refers to a device itself. Some examples of nodes are computers, printers, and servers.

A number that uniquely identifies a network board. The number is acquired dynamically by each node when it comes up on a network. A node address is often referred to as a node number, but some node numbers are factory set rather than being dynamic.

A number that uniquely identifies a network board, also known as the station address, physical node address, and node address.

Every node must have at least one network board, by which the node is connected to the network. Each network board must have a unique node number to distinguish it from all other network boards on that network.

Node numbers are assigned in several ways, depending on the network board type. For example, Ethernet and token ring boards are factory-set (with no two Ethernet boards having the same number), while ARCnet board numbers are set with jumpers or switches. Node addresses are dynamically assigned each time the node is started.

Describes processes that do not give up control of the CPU, but run to completion. Contrast with blocking.

In NLM programming, a function that does not relinquish control of the CPU, but runs to completion. Contrast with blocking function.

An NDS class that cannot be used to create an object in the NDS tree. Noneffective classes are used to define other classes. For example, Server is a noneffective class used to define the effective class Print Server. Contrast with effective class.

NetWare 3.x and above is built around a fast, real-time, multitasking, nonpreemptive thread scheduler. Threads are scheduled according to priority levels and are executed on a run-to-completion basis. Since NetWare does not restrict a thread’s execution by imposing time limits or preempting control of the CPU, a thread is responsible for its own conduct.

NDPS. Print services software that allows network administrators to manage network printing from within NDS. Features include bi-directional feedback, configurable event notification, automatic printer driver download function, protocol independence, and backward compatibility.

A Novell agency that works with manufacturers to test hardware and software components designed to interoperate with the NetWare OS.

NLS. A distributed, enterprise network service that enables administrators to monitor and control the use of licensed applications on the network. NLS also provides a basic license metering tools and libraries that export licensing service functionality to developers of other licensing systems.

NMAS. A flexible and expandable login and authentication framework that provides developers the means to integrate multiple authentication services into NDS systems.
