N
near-letter-quality (NLQ)
A print mode on high-end dot-matrix printers that produces clearer, darker characters than normal (draft mode) printing. Near-letter-quality printing, although it is sharper than plain dot-matrix printing, is not as readable as output from a fully-formed character printer, such as a daisy-wheel printer.
network
An arrangement of two or more computers interconnected by a communication system.
network adapter
Also called interface adapter; an expansion card or other device used to connect a computer to a local area network.
network address
In a network, every node has one or more addresses associated with it, including a Hardware address assigned by the device's manufacturer. Most nodes also have protocol-specific addresses assigned by a network manager.
Network Interface Card (NIC)
A card with the necessary software and electronics to enable a device to communicate over a network.
Network Operating System (NOS)
An operating system which integrates the operations of devices linked by cable or telecommunications. Examples specifically for networked PCs and servers include: Novell's NetWare, Banyan's VINES and IBM's LAN Server.

NLQ
(See "near-letter-quality (NLQ)".)
NLQ (Near Letter Quality)
Dot-matrix printing that is darker and clearer than normal draft-mode printing.
(Also see "letter quality".)
node
A device on a network. A point to which communications can be addressed. A receive and send point.
non-interlaced scanning mode
A scheme for painting an on-screen image that paints all the lines in one pass and then paints an entirely new frame. A non-interlaced scanning mode reduces flicker.
non-static
A term describing the characteristic of a specially treated monitor that prevents build-up of static electricity on the monitor surface.
nonimpact printer
Any printer that makes marks on the paper without striking it mechanically. The most common types are ink-jet, thermal and laser printers.
noninterlaced
An adjective describing a display method on raster-scan monitors in which the electron beam scans each line of the screen once during each refresh cycle. Noninterlaced displays effectively pay attention to every pixel on every line on the screen as the electron beam sweeps across and down the inner surface.
(Also see "interlacing".)
NOS
(See "Network Operating System (NOS)".)
notebook
Portable computer; any computer designed to be moved easily.
numeric keypad
A calculator-style block of keys at the right side of the keyboard that can be used to enter numbers.
