VLAN

VLAN ID

Virtual LAN. Group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible.

Virtual Local Area Network identification used by the standard 802.1Q. Being on 12 bits, it allows the identification of 4096 VLANs.

WEP keys

Wired equivalent privacy (WEP) keys are the IEEE 802.11b standard that offers

 

a mechanism for securing wireless LAN data streams. The goals of WEP include

 

access control to prevent unauthorized users who lack a correct WEP key from

 

gaining access to the network, and privacy to protect wireless LAN data streams

 

by encrypting them and allowing de-encryption only by users with the correct

 

WEP keys.

wireless bridge

Designed to connect two or more networks (typically located in different

 

buildings). Bridges connect hard-to-wire sites, noncontiguous floors, satellite

 

offices, school or corporate campus settings, temporary networks, and

 

warehouses. For functional flexibility, the wireless bridge may also be

 

configured as an access point.
