Short for Network Address Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT boxlocated where the LAN meets the Internet makes all necessary IP address translations.
NAT serves three main purposes:
Provides a type of firewallby hiding internal IP addresses
Enables a company to use more internal IP addresses. Since they’re used internally only, there’s no possibility of conflict with IP addresses used by other companies and organizations.
Allows a company to combine multiple ISDN connections into a single Internet connection.
Short for Global Positioning System, a worldwide MEOsatellite navigational system formed by 24 satellites orbiting the earth and their corresponding receivers on the earth. The satellites orbit the earth at approximately 12,000 miles above the surface and make two complete orbits every 24 hours. The GPS satellites continuously transmit digital radio signals that contain data […]
A type of network computer designed to execute Java programs locally. NCs do not contain any storage devices, so they must be connected to a network server that holds the data to be processed. However, unlike thin clients and Windows terminals, NCs do have a microprocessor so that they can execute programs locally.
Acronym for NetWare Core Protocol. NCP, or NetWare Core Protocol is the file-sharing protocol between server and client(s) on a Novell NetWare network. NCP controls many requests to the file and printing system, along with login requests. NCP is a client/server LAN protocol. Clients (or workstations) send NCP requests, which are sent via IPX or […]
Short for Network Driver Interface Specification, a Windows device driver interface that enables a single network interface card (NIC) to support multiple network protocols. For example, with NDIS a single NIC can support both TCP/IP and IPX connections. NDIS can also be used by some ISDN adapters. NDIS includes a protocol manager that accepts requests […]
Short for Network Data Management Protocol, a protocol pioneered by Intelliguard and Network Appliance that defines a common architecture for the way heterogeneous file servers on a network are backed up. The protocol will allow the creation of a common agent used by the central back-up application to back up different file servers running different […]
