Hub
A box with several Ethernet connectors. Ethernet hubs provide a common
point of contact for all connected devices.
IP address
A number assigned to your computer by your cable company, used to iden-
tify your computer to other systems on the Internet.
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 Data Gateway’s MAC address to authorize access
to the Internet. The MAC address is printed on a label on the bottom of your
Data 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.
RF
Abbreviation for Radio Frequency. Some literature refers to coax as “RF
cable” and the connectors as “RF connectors.”

A standard 2-conductor modular connector, commonly used in North Amer-
ica for connecting telephones.
RJ-45
A standard 8-conductor modular connector, commonly used on Ethernet
cable. An RJ-45 connector looks like a wide RJ-11 (telephone) connector.
Splitter
A small box with three cable connectors: one input and two outputs. You
may need a splitter if you have a TV already connected to the cable outlet
that you want to use for your Data Gateway. You can buy a splitter from any
electronics retailer and most discount stores.
SSID
Service Set IDentifier, a string of text (up to 32 characters long) that
uniquely identifies a wireless LAN.
Switched outlet
A power outlet that may be turned on and off using a wall switch. Usually
intended for lamps. Avoid plugging your computer or Data Gateway into a
switched outlet to avoid disruptions.
TCP/IP
Transmission Control Protocol/Internet Protocol. The protocols used to facil-
itate communications across one or more connected networks.
TDMA
Time Division Multiple Access. A method used by DOCSIS-compliant cable
modems for sending upstream data with minimal interference.
Upstream
The path from a subscriber device to the headend. Some older cable docu-
mentation may refer to this as the return path or reverse path.
WEP
Wired Equivalent Privacy, a common standard for encrypting data sent over
a wireless LAN.
