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.
