Bridge - A device that connects two different kinds of local networks, such as a wireless network to a wired
Ethernet network.
Broadband - An always-on, fast Internet connection.
Browser - A browser is an application program that provides a way to look at and interact with all the
information on the World Wide Web.
DDNS (Dynamic Domain Name System) - The capability of having a website, FTP, or e-mail server-with a
dynamic IP address-use a fixed domain name.
Default Gateway - A device that forwards Internet traffic from your local area network.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets one device on a local network, known as a
DHCP server, assign temporary IP addresses to the other network devices, typically computers.
Domain - A specific name for a network of computers.
DSSS (Direct-Sequence Spread-Spectrum) - A type of radio transmission technology that includes a redundant
bit pattern to lessen the probability of data lost during transmission. Used in 802.11b networking.
Dynamic IP Address - A temporary IP address assigned by a DHCP server.
Encryption - Encoding data to prevent it from being read by unauthorized people.
Ethernet - An IEEE standard network protocol that specifies how data is placed on and retrieved from a common
transmission medium.
Firmware - 1. In network devices, the programming that runs the device. 2. Programming loaded into read-only
memory (ROM) or programmable read-only memory (PROM) that cannot be altered by end-users.
Gateway - A system that interconnects networks.
Hardware - The physical aspect of computers, telecommunications, and other information technology devices.
HTTP (HyperText Transport Protocol) - The communications protocol used to connect to servers on the World
Wide Web.
IEEE (The Institute of Electrical and Electronics Engineers) - An independent institute that develops networking
standards.
Infrastructure - Currently installed computing and networking equipment.
Infrastructure Mode - Configuration in which a wireless network is bridged to a wired network via an access
point.
IP (Internet Protocol) - A protocol used to send data over a network.
IP Address - The address used to identify a computer or device on a network.
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.
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.
Network - A series of computers or devices connected for the purpose of data sharing, storage, and/or
transmission between users.
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.
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.
Software - Instructions for the computer. A series of instructions that performs a particular task is called a
"program".
SSID (Service Set IDentifier) - Your wireless network's name.
