Schools are increasingly using the walled garden approach in creating browsing environments in their networks.
Students have access to only limited Web sites, and teachers need a password in order to leave the walled garden
and browse the Internet in its entirety.
The term walled garden also commonly refers to the content that wireless devices such as mobile phones have
access to if the content provided by the wireless carrier is limited.
WAN
Wide Area Network. A communication system of connecting PCs and other computing devices across a large local,
regional, national or international geographic area. Also used to distinguish between phone-based data networks
and Wi-Fi. Phone networks are considered WANs and Wi-Fi networks are considered Wireless Local Area Networks
(WLANs).
WEP
Wired Equivalent Privacy. Basic wireless security provided by Wi-Fi. In some instances, WEP may be all a home or
small-business user needs to protect wireless data. WEP is available in 40-bit (also called 64-bit), or in 108-bit (also
called 128-bit) encryption modes. As 108-bit encryption provides a longer algorithm that takes longer to decode, it
can provide better security than basic 40-bit (64-bit) encryption.
Wi-Fi
Wireless Fidelity. An interoperability certification for wireless local area network (LAN) products based on the
Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards.
WLAN
Wireless Local Area Network. Also referred to as WLAN. A type of local-area network that uses high-frequency radio
waves rather than wires to communicate between nodes.
WPA-Enterprise (Wi-Fi Protected Access)
Stands for Wi-Fi Protected Access – Enterprise. It is Wi-Fi's encryption method that protects unauthorized network
access by verifying network users through a server.
WPA-Personal
Stands for Wi-Fi Protected Access – Personal. It is Wi-Fi's encryption method that protects unauthorized network
access by utilizing a set-up password.
WPA2
Wi-Fi Protected Access version 2. The follow on security method to WPA for Wi-Fi networks that provides stronger
data protection and network access control.
