Internet Group Management Protocol An Internet protocol that
enables a computer to share information about its membership in
multicast groups with adjacent routers. A multicast group of
computers is one whose members have designated as interested
in receiving specific content from the others. Multicasting to an
IGMP group can be used to simultaneously update the address
books of a group of mobile computer users or to send company
newsletters to a distribution list.

The global collection of interconnected networks used for both
private and business communications.
A private, company-internal network that looks like part of the
Internet (users access information using web browsers), but is
accessible only by employees.
See TCP/IP.
Internet Protocol address The address of a host (computer) on
the Internet, consisting of four numbers, each from 0 to 255,
separated by periods, e.g., 209.191.4.240. An IP address consists
of a network ID that identifies the particular network the host
belongs to, and a host ID uniquely identifying the host itself on
that network. A network mask is used to define the network ID
and the host ID. Because IP addresses are difficult to remember,
they usually have an associated domain name that can be
specified instead. See also domain name, network mask.
Internet Service Provider A company that provides Internet
access to its customers, usually for a fee.
Local Area Network A network limited to a small geographic
area, such as a home, office, or small building.
Light Emitting Diode An electronic light-emitting device. The
indicator lights on the front of the My ADSL Modem are LEDs.
Media Access Control address The permanent hardware address
of a device, assigned by its manufacturer. MAC addresses are
expressed as six pairs of characters.
: See network mask.
Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
In splitterless deployments, a microfilter is a device that removes
the data frequencies in the DSL signal, so that telephone users do
not experience interference (noise) from the data signals.
Microfilter types include in-line (installs between phone and
jack) and wall-mount (telephone jack with built-in microfilter).
See also splitterless.
