IP address
IP address. An address that identifies a specific host to the Internet protocol (IP). An IP
address consists of two parts: a network address, which identifies the network, and a
local address, which identifies a host within a network. A network address is
concatenated with a host address to form the IP address and uniquely identify a host
within a network. IP routes data between source and destination IP addresses.
LAN. See local area network (LAN)
.
local area network (LAN). A network that is located in a small geographical area and whose
communications technology provides a high-bandwidth, low-cost medium to which
low-cost nodes can be connected. One or more LANs can be connected to the system
such that the LAN users can access the system as if their workstations were connected
directly to it.
leased line. A dedicated telephone line between two locations.
MAC. See media access control (MAC).
MAC address. See media access control (MAC) address.
media access control (MAC). A protocol that defines how devices access a network.
media access control (MAC) address. A value in the Medium Access Control sublayer of
the IEEE/ISO/ANSI local area network (LAN) architecture that uniquely identifies an
individual station implementing a single point of physical attachment to a LAN.
PAP. See Password Authentication Protocol (PAP).
PARAM. A Tandem Advanced Command Language (TACL) command and a Subsystem
Control Facility (SCF) command you can use to create a parameter and give it a value.
The TACL process stores the values of parameters assigned by the PARAM command
and sends the values to applications, such as SYSGENR, that request parameter values.
Password Authentication Protocol (PAP). A protocol that uses a two-way handshake to
establish the identity of the user. PAP is less secure than the Challenge Handshake
Authentication Protocol (CHAP).
Point-to-Point Protocol (PPP). A data communications protocol that provides a standard
method of encapsulating Internet Protocol (IP), Internet Packet Exchange (IPX), and
AppleTalk information over point-to-point links. Supports transmissions of over a serial
line that directly connects two points.
PAP. See Password Authentication Protocol (PAP).
RAS. See Remote Access Server (RAS).
Remote Access Server (RAS). A network device that connects to analog telephone lines or
ISDN BRI lines. It allows users to dial into and out of the corporate local area network
(LAN) from workstations. The AWAN access server can be configured to function as a
RAS.
