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.
