IP address 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 identies 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 dene the network ID and the host
ID. Because IP addresses are difcult to remember, they usu-
ally have an associated domain name that can be specied
instead. Seedomainname,networkmask.
ISP Internet Service Provider
A company that provides Internet access to its customers,
usually for a fee.
LAN Local Area Network
A network limited to a small geographic area, such as a home
or small ofce.
LED Light Emitting Diode
An electronic light-emitting device. The indicator lights on the
front of the Wireless ADSL2+ Router are LEDs.
MAC address 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.
mask Seenetworkmask.
Mbps Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
NAT Network Address Translation
A service performed by many Routers that translates your
network’s publicly known IP address into a private IP address
for each computer on your LAN. Only your Router and your
LAN know these addresses; the outside world sees only the
public IP address when talking to a computer on your LAN.
