ISDN
Integrated Services Digital Network. A digital telephony standard that pro-
vides communication speeds about twice as fast as standard dialup.
LAN
Local Area Network. A network that allows computers in a single location
(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 Modem's MAC address to authorize
access to the Internet. The MAC address is printed on a label on the bot-
tom of your Telephony Modem.
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."
RJ-11
A standard modular connector carrying two wires, commonly used in North
America for connecting telephones. The same connector carrying four
wires (for a two-line telephone connection) is called an RJ-14.
