Extended TACACS (XTACACS)
Extended TACACS (XTACACS). A network-based authentication/authorization protocol.
FASTPTCP. The Tandem Spooler output driver support by the AWAN access server Telnet
services 2001 through 2064.
file transfer protocol (FTP). A data communications protocol that is used for transferring
files between systems.
flash memory. A semiconductor device that retains stored information whether power to the
unit is on or off. Information in flash memory can be overwritten with new information
when necessary.
GAP. See Gateway Access Protocol (GAP)
.
gateway. Equipment that provides interconnection between two networks with different
communications protocols.
Gateway Access Protocol (GAP). A proprietary third-party product provided by Gemini
Communications, Inc., which adds support to the AWAN access server for non-standard
devices and advanced asynchronous features.
gateway address. The Internet Protocol (IP) address of the entrance to the network.
handshaking. A preliminary exchange of predetermined signals by modems and/or terminals
to ensure a positive connection.
initialization string. Several short commands that a computer sends to a modem. These
commands give the modem instructions to set it to a predetermined state.
Internet Packet Exchange (IPX). A Novell protocol that performs addressing and
internetwork routing functions to ensure data reaches the appropriate destination. IPX
moves data between programs running on different nodes.
Internet Packet Exchange (IPX) address. The address of a network node that is assigned
and recognized by Novell's Netware software. This number consists of the network and
the node's media access control (MAC) address.
Internet protocol (IP). A data communications protocol that handles the routing of data
through a network, which typically consists of many different subnetworks. IP is
connectionless; it routes data from a source address to a destination address.
Internet address. The 32-bit address assigned to hosts that want to participate in the Internet
using Transmission Control Protocol over Internet Protocol (TCP/IP). Internet addresses
are an abstraction of physical hardware addresses, just as the Internet is an abstraction of
physical networks. As assigned to the interconnection of a host to a physical network, an
Internet address consists of a network portion and a host portion.
