tify your computer to other systems on the Internet.

(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 Wideband Cable Modem’s MAC address to author-
ize access to the Internet. The MAC address is printed on a label on the bot-

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.
RF
Abbreviation for Radio Frequency. Some literature refers to coax as “RF
cable” and the connectors as “RF connectors.”
