of PCs on a LAN and allows communication to pass between
the networked devices.

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 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.
ISP Internet Service Provider

usually for a fee.
LAN Local Area Network

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.
