USB
Universal Serial Bus (USB) is a standard that was developed by the USB Implementers
Forum, Inc., to connect computers and peripherals. Unlike the parallel port, USB is
designed to concurrently connect a single computer USB port to multiple
peripherals.
Watermark
A watermark is a recognizable image or pattern in paper that appears lighter when
viewed by transmitted light. Watermarks were first introduced in Bologna, Italy in
1282; they have been used by papermakers to identify their product, and also on
postage stamps, currency, and other government documents to discourage
counterfeiting.
WEP
Wired Equivalent Privacy (WEP) is a security protocol specified in IEEE 802.11 to
provide the same level of security as that of a wired LAN. WEP provides security by
encrypting data over radio so that it is protected as it is transmitted from one end
point to another.
WIA
Windows Imaging Architecture (WIA) is an imaging architecture that is originally
introduced in Windows Me and Windows XP. A scan can be initiated from within
these operating systems by using a WIA-compliant scanner.
WPA
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-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.
WPS
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.
XPS
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.
