One million cycles per second. A unit of measure for frequency.
Motherboard
The main circuit board on a computer. The motherboard includes processor, RAM, support circuitry, and a bus controller.
Motion JPEG
A variation of JPEG, this is a compression scheme for video files. See also JPEG.
MPC (Multimedia Personal Computer)
A specification for multi media hardware- speakers, sound cards, video cards, Cd drives, and so on-that ensures the hardware is compatible, reliable, and meets certain quality standards.
MPEG (Moving Picture Experts Group)
A graphic file format that enables video to be stored in compressed form.
MS-DOS-based application
MS-DOS applications were built for the original MS-DOS operating system. Some MS-DOS programs can run in Windows and others cannot.
Multitasking
The simultaneous execution of two or more programs in a Windows or OS/2 operating system.
Multithreading
A process by which Windows can multitask portions, or threads, of a program.
Narrowband Transmission
One in which the data transfer is slow or has a small transfer rate.
NDIS (Network Driver Interface Specification)
A set of functions that causes a request to be submitted to the operating system or causes a request to be submitted to the operating system or causes a local action to be performed. Mainly, the NDIS enables protocol drivers to send and receive packets on the network.
NetBEUI (NetBIOS Extended User Interface)
A Microsoft protocol you can use with any Windows program- most commonly used with Windows for Workgroups, Windows 95/98, and Windows NT, and very seldom used with Windows Me, 2000, and XP. NetBEUI is easy to set up, provides good performance, and is a fast protocol. NetBEUI uses very little memory and also provides good error detection over the network.
NetBIOS (Network Basic Input/Output system)
A programming interface for developing client/server applications; NetBIOS also works with other protocols and various network types.
Network
A system that connects two or more computers plus peripherals (Printers, CD- ROM drives, scanners, and so on) so that all computers can communicate and share resources with each other.
See network interface card. Another way of referring to the IP
address.The
Network Adapter Network Address
IP address is the address for a computer, printer, or other device on the network. See also IP.
Networks Applications
Network applications come in two parts: client and server. The server part of the application is installed on a server computer; on a workgroup network, it is installed on a workstation that serves as a host. The client part of the software installs on the rest of the computers on the network. The client requests some service, and the server grants the request.
Network Commands
Windows includes several network commands you can use at the MS-DOS prompt. These commands enable you to view your current network connections, view any computer’s shared resources, and even create permanent connections, or drive mappings.
Network Interface Card (NIC)
Also called network card or a network adapter, this is A circuit board installed in your computer that uses specific software drivers to work with your computer and attaches to the network by means of a network cable or a wireless connection
Network Layer
One of the ISO/OSI layers. The network layer defines the protocols for data routing, to make sure the data gets to the correct destination.
Network Operating System (NOS)
Designed specifically for a server, a NOS offers many features and tools that help you manage clients, applications, security, and other facets of the network.
Network Path
A path that leads to a computer on the network, and then to a folder or file on that computer . For example, \ \Sue\My Documents\My Pictures leads to the My Pictures folder on Sue's computer over the network. (The double backslashes tell the operating system to locate the following over the network instead of on the local computer.)
NFS (Network File System)
NFS enables a computer to use files and peripherals as if they were local
Node
Any device connected to a network, such as a client, server, hub, printer, and so on.
Noninterlacing
Interlacing refers to how a monitor refreshes, or redraws, the screen. Interlacing monitors skip every other line during the redraw process, thus producing a flicker or jitter on the screen. Noninterlaced monitors scan every line, providing the best screen quality.
Null Modem
A cable used to connect two computers. Data flows from one computer to the other, only in one direction at a time, so the two computers cannot try to send data to each other simultaneously. A null modem cable is an RS- 232-C cable. A null modem cable connects the serial ports.
Operating System (OS)
The software that controls hardware resources and enables you to interact with the computers applications.Windows XP, Macintosh system 8, 9 and OS X, and Slackware are operating systems.
184 Sales and Support, Call: 1300 ADI ADI Packet
Data is over a network in packets, or blocks.Each packet not only contains a part of the data you want to send, but only contains the name of the sender and receiver and some error-control information to help make sure th packet makes it to its destination in one piece.
Parallel Port
An input/output port that manages information 8 bits at a time; parallel ports are often used for connecting printers to a computer as well. You generally can find a highspeed direct parallel cable at any computer store.
Partitioning
Refers to dividing your hard disk into sections. The operating system treats different partitions on a hard disk as if they were separate drives.
Patch panel
Patch panels contain 8, 12 or 24 jacks within a strip for easy connection to solid cables. You can attach the patch panel to the wall, insert the solid cables, and then insert the patch cables on the other side-leading to your hub- for safe and effective wiring of your network.
Path
Defines the complete location of a file or folder, such as c:/Windows/program files. A network path begins two backlashes, to identify the path as a network path, such as \\Sue\My Documents.
PC (Personal Computer)
A microcomputer for use by an individual, as in an office or at home or school. Also, an IBM- compatible computer, as opposed to a macintosh.
PC Card
A type of PCMCIA card. The card is smaller than normal adapter cards and works with portable computers to provide functionality for modems, sounds, videos, and other devices.
PCI (Peripheral Component Interface Bus)
An Intel specification that defines a local bus that enables up to ten PCI- compliant expansion cards to be plugged into the computer.
PMCIA (Personal Computer Memory Card International Association)
PCMCIA is a standard for portable computers. The PCMCIA card is usually the size of a credit card. Their are several versions, or types, of PCMCIA cards; the types define the thickness and uses of the card.
Peer-to-Peer Network
A network in which all computers of the network have an equal rank; all share their resources-including files, folders, drives, printers, and so on - with all others on the network. See also workgroup network.
Permissions
Simi lar to r ights, permissions are characteristics given to users of a network to allow or prevent access to files and other resources on the network. See Rights.
Physical Layer
One of the ISO\OSI layers. The physical layer defines the cabling.

www.adiglobal.com/au OSI Model (open systems Interconnection)
A seven-layer model that establishes a standard set of protocols for interoperability between networked computers.
