Wi-Fi Protected Access (WPA) is a class of systems to secure wireless (Wi-Fi) computer networks,
which was created to improve upon the security features of WEP.
WPA-PSK (WPA Pre-Shared Key) is special mode of WPA for small business or home users. A
shared key, or password, is configured in the wireless access point (WAP) and any wireless laptop or
desktop devices. WPA-PSK generates a unique key for each session between a wireless client and the
associated WAP for more advanced security.
The Wi-Fi Protected Setup (WPS) is a standard for establishing a wireless home network. If your
wireless access point supports WPS, you can configure the wireless network connection easily
without a computer.
XML Paper Specification (XPS) is a specification for a Page Description Language (PDL) and a new
document format, which has benefits for portable document and electronic document, developed
by Microsoft. It is an XML-based specification, based on a new print path and a vector-based
device-independent document format.
