WAN Wide-Area Network. A wide-area network consists of groups of interconnected
computers that are separated by a wide distance and communicate with each other via

WEP WEP is widely used as the basic security protocol in Wi-Fi networks, which secures
data transmissions using 64-bit or 128-bit encryption.
Windows Windows is a graphical user interface for workstations that use DOS.
WPA WPA (Wi-Fi Protected Access ) is used to improve the security of Wi-Fi networks,
replacing the current WEP standard. It uses its own encryption, Temporal Key Integrity
Protocol (TKIP), to secure data during transmission.
WPA2 Wi-Fi Protected Access 2, the latest security specification that provides greater data
protection and network access control for Wi-Fi networks. WPA2 uses the government-
grade AES encryption algorithm and IEEE 802.1X-based authentication, which are
required to secure large corporate networks.
