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

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.

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.

(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.

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
