IP address
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.
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.
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.
PARAM. An HP 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.
RAS. See Remote Access Server (RAS).
Remote Access Server (RAS). A network device, or router, 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 and the
DECservers can be configured to function as a RAS.
RS-232. An industry standard for serial data transmission. It describes pin assignments,
signal functions, and electrical characteristics. The current standard specifies a 25-pin
connector.
