characteristics of the image that is included in the file. This flexible and
platform-independent format can be used for pictures that have been
made by various image processing applications.
Toner Cartridge
A kind of bottle within a machine like printer which contains toner. Toner
is a powder used in laser printers and photocopiers, which forms the text
and images on the printed paper. Toner can be melted by the heat of the
fuser, causing it to bind to the fibers in the paper.
TWAIN
An industry standard for scanners and software. By using a
TWAIN-compliant scanner with a TWAIN-compliant program, a scan can
be initiated from within the program.; an image capture API for Microsoft
Windows and Apple Macintosh operating systems.
UNC Path
Uniform Naming Convention (UNC) is a standard way to access network
shares in Window NT and other Microsoft products. The format of a
UNC path is: \\<servername>\<sharename>\<Additional directory>
URL
Uniform Resource Locator (URL) is the global address of documents
and resources on the Internet. The first part of the address indicates
what protocol to use, the second part specifies the IP address or the

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,

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.
