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.
Mask A filter that includes or excludes certain values, for example parts of an IP address.
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.

TCP/IP (Transmission Control Protocol/Internet Protocol) A set of instructions PCs use to communicate over a network.
Telnet A user command and TCP/IP protocol used for accessing remote PCs.
Throughput The amount of data moved successfully from one node to another in a given time period.
TKIP (Temporal Key Integrity Protocol) A wireless encryption protocol that provides dynamic encryption keys for each packet transmitted.
Topology The physical layout of a network. TX Rate Transmission Rate.
