name resolution. The process used on the network to determine the address of a computer by using its name.
native. A term used to identify software that runs only on a particular platform.
navigation. The act of finding your way through data, a program, a disk, or a network. In software application, navigations refers to moving the insertion point (or cursor) around the document. Proper navigation lets you edit and manipulate a document more efficiently.
NCSA Telnet. NCSA Telnet is a freeware Telnet client developed by the National Center for Supercomputing Applications (NCSA). Using the Telnet protocol, it allows you to interface with computer systems throughout the world via the Internet. When connected, NCSA Telnet becomes a virtual computer terminal, letting you interact with the remote host from your Mac. Unlike ZTerm and similar terminal programs, NCSA Telnet has no built-in way to communicate with your modem. Instead, it requires you to have an Internet connection, such as one established via PPP or Ethernet. You must also have MacTCP or Open Transport installed on your computer.
NetBIOS. Abbreviation for Network Basic Input/Output System. The BIOS tells a computer what types of devices and memory are connected to the computer and how to find them. A network BIOS includes basic information about the network to a which a computer is connected.
NetWare. The networking software; the file server's operating system. Most closely associated with Novell, as in Novell Netware, the operating system used on Novell networks.
network. A group of computers and other devices that can interact by means of a shared communications link.
network adapter. A hardware device (or card) that establishes a network and enables a computer to connect to another computer with a similar device. All computers in a network should use compatible adapters.
network ID. The portion of the IP address that identifies a group of computers and devices located on the same logical network. Separated from the host ID using the subnet mask.
Network interface card (NIC. ) An adapter card that connects a computer to a network.
newsgroups. The development of a network linking computers together to share discussion groups. There are literally tens of thousands of different newsgroups discussing virtually every subject imaginable. From operating systems to sports, politics, religion, and entertainment.
node. A single computer or terminal in a network. Networks can consist of numerous nodes, each operating independently.
NRZI. Non-Return-to-Zero Inverted. A method for transmitting and recording data so that it keeps the sending and receiving clocks synchronized. This is especially helpful in situations where bit stuffing is employed -- the practice of adding bits to a data stream so it conforms with communications protocols. These added bits can create a long string of similar bits, which register to the receiver as a single, unchanging voltage. Since clocks adjust on voltage changes, they'll lag behind true time. NRZI ensures that after a 0 bit appears, the voltage will immediately switch to a 1 bit voltage level. These voltage changes allow the sending and receiving clocks to synchronize.
