Hub

A box with several Ethernet or USB connectors. Ethernet hubs provide a

common point of contact for all connected devices; USB hubs allow you to

add peripherals without installing a USB card in your computer.

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

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 bottom

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.
