GLOSSARY

10BaseT or 100BaseTx: 802.3 based Ethernet network that uses UTP (Unshielded twisted pair) cable and a star topology. 10 is 10 Mbps and 100 is 100 Mbps.

802.1x:The standard for wireless LAN authentication used between an AP and a client. 802.1x with EAP will initiate key handling.

AdHoc Network:The wireless network based on peer-to-peer for the duration of a communications session. Also referred to as Ad-Hoc.

Address Aging Period: The maximum time during which the forwarding database entries are considered valid. This value should be set low if your network has regularly heavy traffic. Each new device that sends a packet to a device has its MAC address added to the System Forwarding Database. The Database can store up to a maximum of 8192 MAC addresses at any one time. After the maximum number of MAC addresses has been reached, the earliest stored addresses are overwritten with new, incoming information.

AES (Advanced Encryption Standard):

A symmetric 128bit block data encryption technique used for security.

Bandwidth: The transmission capacity of a computer, or a communication channel, stated in Megabits per second (Mbps).

BOOTP: Software protocol used by servers. When the client PC starts, it contacts the server, and requests a new set of IP Configura- tions. The server obtains the new IP Configu- ration information from a static pool of available addresses.The client PC will keep its IP Configuration information until it is turned off and restarted. BOOTP is not always fully supported in newer operating systems.

BNC (British Naval Connector): A BNC connector has a bayonet-type shell with two small knobs on the female connector, which twist-lock into slots in the male connector. Used with coaxial cable.

BSS (Basic Service Set): An 802.11 networking framework that includes an Access Point.

Bus Mastering: A system in which the specified Input/Output device (e.g., NIC Card) can perform tasks without the intervention of the CPU.
