IP address
A number assigned to your computer by your cable company, used to iden-
tify your computer to other systems on the Internet.
ISDN

vides communication speeds about twice as fast as standard dialup.

(such as a building) to communicate with one another.
LED
Light Emitting Diode. A semi-conductor diode that emits light when current
is passed through it.
MAC address
A number that uniquely identifies any device connected to a network. Your
cable company uses your Telephony Gateway's MAC address to authorize
access to the Internet. The MAC address is printed on a label on the bottom
of your Telephony Gateway.
Protocol
A set of rules and formats that determines the communication behavior of
network entities at a given layer.
Proxy
A device or program that stands in between a server (for example, a web
site) and a client (your browser), providing a way to relieve some of the
burden from the server. For example, your cable company may have a web
proxy that keeps copies of popular web pages; the proxy can send you those
pages instead of fetching them directly from the web site, resulting in faster
page loading and less network congestion.
