A hub is a place of convergence where data arrives from one
or more directions and is forwarded out in one or more
directions. It connects an Ethernet bridge to a group of PCs
on a LAN and allows communication to pass between the
networked devices.
Internet Control Message Protocol
An Internet protocol used to report errors and other network-
related information. The ping command makes use of ICMP.
The Institute of Electrical and Electronics Engineers is a
technical professional society that fosters the development of
standards that often become national and international
standards.
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 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 or small office.
Light Emitting Diode
An electronic light-emitting device. The indicator lights on the
front of the Wireless Gateway 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 hex characters, with each pair separated by colons. For
example; NN:NN:NN:NN:NN:NN.
See network mask.
Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
Network Address Translation
A service performed by many Wireless APs that translates
your network's publicly known IP address into a private IP
address for each computer on your LAN. Only your Wireless
AP and your LAN know these addresses; the outside world
