HOTSPOT GATEWAY
Glossary of Terms 333
Internet Service Provider
The agency that provides you with access to the Internet. Your Internet Service Provider (ISP) may be a
large commercial organization (for example, America Online) or, if you access the Internet via your
employer, then your employer is your Internet Service Provider. See also, Internet.
Intranet
A network confined to a single organization (but not necessarily a single site). Usually thought of as a
corporate mini Internet.
IP
See Internet Protocol.
IP Address
The numeric address of a device, in the format used on the Internet. The actual numeric value takes the
form of a 32-bit binary number broken up into four 8-bit groups, with each group separated by a period (for
example, 198.43.7.85). To make it easier for the user, the IP address is mapped to a meaningful domain
name. IP addresses can be static (permanent) or dynamic (assigned each time you connect). See also,
Domain Name, Dynamic IP Address, Internet Protocol, and Static IP Address.
IP Address Translation
Nomadix Gateways use adaptive configuration technology which can accommodate all network
configurations, including dynamic and static IP address assignments. This enables it to solve IP addressing
problems in environments where the service provider does not have control over the subscriber’s network
settings. Whenever a subscriber logs on, your Nomadix Gateway automatically translates their computer’s
network settings to provide them with seamless access to the broadband network. Subscribers no longer
need to alter their computer’s settings. See also, Dynamic IP Address, IP Address, and Static IP
Address.
ISDN
(Integrated Services Digital Network) An international communications standard for sending voice, video,
and data over digital telephone lines or normal telephone wires. ISDN supports data transfer rates of 64
Kbps (64,000 bits per second).
ISP
See Internet Service Provider.
LAWN
(Local Area Wireless Network) A type of Local Area Network that uses high-frequency radio waves rather
than wires to communicate between nodes. Also referred to as WLAN. See also, Node.
LDAP
(Lightweight Directory Access Protocol) Directories containing information such as names, phone
numbers, and addresses are often stored on a variety of incompatible systems. LDAP provides a simple
protocol that allows you to access and search these disparate directories over the Internet. LDAP is
commonly used for online billing applications.
MAC Address
(Media Access Control) The hardware address that uniquely identifies each node of a network. In IEEE
802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub
layers – the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer
interfaces directly with the network media. Consequently, each type of network media requires a different
MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI
Reference Model, the node address is called the Data Link Control (DLC) address.
