server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address.
Default Gateway
- A device that forwards Internet traffic from your local area network.
DHCP
(Dynamic Host Configuration Protocol) - A networking protocol that allows
administrators to assign temporary IP addresses to network computers by "leasing" an IP
address to a user for a limited amount of time, instead of assigning permanent IP addresses.
DMZ
(Demilitarized Zone) - Removes the Router's firewall protection from one PC, allowing it to
be "seen" from the Internet.

(File Transfer Protocol) - A protocol used to transfer files over a TCP/IP network.
Full Duplex
- The ability of a networking device to receive and transmit data simultaneously.
Gateway
- A device that interconnects networks with different, incompatible communications
protocols.
Half Duplex
- Data transmission that can occur in two directions over a single line, but only one
direction at a time.
HTTP
(HyperText Transport Protocol) - The communications protocol used to connect to
servers on the World Wide Web.
Infrastructure
- A wireless network that 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.
ISP
(Internet Service Provider) - A company that provides access to the Internet.
LAN
- The computers and networking products that make up your local network.
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.

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.
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 mail server commonly used on the Internet.
Port
- The connection point on a computer or networking device used for plugging in cables or
adapters.
PoE
(Power over Ethernet) - A technology enabling an Ethernet network cable to deliver both
data and power.
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.
RADIUS
(Remote Authentication Dial-In User Service) - A protocol that uses an authentication
server to control network access.
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.
