Wireless-G Range Expander DSSS (Direct-Sequence Spread-Spectrum) - Frequency transmission with a redundant bit pattern resulting in a lower probability of information being lost in transit. Encryption - Encoding data transmitted in a network. Firmware - The programming code that runs a networking device. Fragmentation -Breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. Gateway - A device that interconnects networks with different, incompatible communications protocols. Hardware - The physical aspect of computers, telecommunications, and other information technology devices. IEEE (The Institute of Electrical and Electronics Engineers) - An independent institute that develops networking standards. 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. ISM band - Radio bandwidth utilized in wireless transmissions. MAC (Media Access Control) Address - The unique address that a manufacturer assigns to each networking device. 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. 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. Port - The connection point on a computer or networking device used for plugging in cables or adapters. RADIUS (Remote Authentication Dial-In User Service) - A protocol that uses an authentication server to control network access. Appendix E: Glossary 29
