Wireless-G Ethernet Bridge

IPCONFIG

- A Windows 2000 and XP utility that displays the IP address for a particular networking device.

IPSec

(Internet Protocol Security) - A VPN protocol used to implement secure exchange of packets at the IP layer.

ISM band

- Radio band used in wireless networking transmissions.

ISP

(Internet Service Provider) - A company that provides access to the Internet.

LAN

(Local Area Network) - The computers and networking products that make up the network in your home or

office.

MAC

(Media Access Control) Address - The unique address that a manufacturer assigns to each networking

device.

Mbps

(Megabits Per Second) - One million bits per second; a unit of measurement for data transmission.

Multicasting

- Sending data to a group of destinations at once.

NAT

(Network Address Translation) - NAT technology translates IP addresses of a local area network to a

different IP address for the Internet.

Network

- A series of computers or devices connected for the purpose of data sharing, storage, and/or

transmission between users.

NNTP

(Network News Transfer Protocol) - The protocol used to connect to Usenet groups on the Internet.

Node

- A network junction or connection point, typically a computer or work station.

OFDM

(Orthogonal Frequency Division Multiplexing) - A type of modulation technology that separates the data

stream into a number of lower-speed data streams, which are then transmitted in parallel. Used in 802.11a,

802.11g, and powerline networking.

Packet

- A unit of data sent over a network.

Passphrase

- Used much like a password, a passphrase simplifies the WEP encryption process by automatically

generating the WEP encryption keys for Linksys products.

Ping

(Packet INternet Groper) - An Internet utility used to determine whether a particular IP address is online.

POP3

(Post Office Protocol 3) - A standard protocol used to retrieve e-mail stored on a mail server.

Port

- 1. The connection point on a computer or networking device used for plugging in a cable or an adapter. 2.

The virtual connection point through which a computer uses a specific application on a server.

Appendix E: Glossary

Wireless-G Ethernet Bridge

PPPoE

(Point to Point Protocol over Ethernet) - A type of broadband connection that provides authentication

(username and password) in addition to data transport.

PPTP

(Point-to-Point Tunneling Protocol) - A VPN protocol that allows the Point to Point Protocol (PPP) to be

tunneled through an IP network. This protocol is also used as a type of broadband connection in Europe.

Preamble

- Part of the wireless signal that synchronizes network traffic.

RJ-45

(Registered Jack-45) - An Ethernet connector that holds up to eight wires.

Roaming

- The ability to take a wireless device from one access point's range to another without losing the

connection.

Router

- A networking device that connects multiple networks together, such as a local network and the Internet.

RTS

(Request To Send) - A packet sent when a computer has data to transmit. The computer will wait for a CTS

(Clear To Send) message before sending data.

Server

- Any computer whose function in a network is to provide user access to files, printing, communications,

and other services.

SMTP

(Simple Mail Transfer Protocol) - The standard e-mail protocol on the Internet.

SNMP

(Simple Network Management Protocol) - A widely used network monitoring and control protocol.

Software

- Instructions for the computer. A series of instructions that performs a particular task is called a

“program”.

Spread Spectrum

- Wideband radio frequency technique used for more reliable and secure data transmission.

SSID

(Service Set IDentifier) - Your wireless network's name.

Static IP Address

- A fixed address assigned to a computer or device that is connected to a network.

Static Routing

- Forwarding data in a network via a fixed path.

Subnet Mask

- An address code that determines the size of the network.

Switch

- 1. Device that is the central point of connection for computers and other devices in a network, so data

can be shared at full transmission speeds. 2. A device for making, breaking, or changing the connections in an

electrical circuit.
