specify the control of relative loudness of
sounds. It also pertains to the function on
many electronic devices that is used to control
the loudness.
W
W (wattage)
A measurement of power. In speakers,
wattage is a term that indicates power-
handling characteristics in dealing with
electrical voltage inputs from the amplifier.
WAP (Wireless Application Protocol)
Global protocol used in some wireless devices
that allows the user to view and interact with
data services. Generally used as a means to
view Internet web pages using the limited
transmission capacity and small display screens
of portable wireless devices.
WAV
A format for sound files developed jointly by
Microsoft and IBM. Built into Windows 95
to XP, which made it the de facto standard
for sound on PCs. WAV sound files end with
a ‘.wav’ extension and works with nearly all
Windows applications that support sound.
WEP (Wired Equivalent Privacy)
All 802.11b (Wi-Fi / wireless) networks use
WEP as their basic security protocol. WEP
secures data transmissions using 64-bit or
128-bit encryption; however, it does not
offer complete security and is usually used in
conjunction with other security measures such
as EAP.
Wi-Fi
Wi-Fi (Wireless Fidelity) is a wireless
technology brand owned by the Wi-Fi Alliance
intended to improve the interoperability of
wireless local area network products based
on the IEEE 802.11 standards. Common
applications for Wi-Fi include Internet and
VoIP phone access, gaming, and network

U
UPnP (Universal Plug and Play)
Universal Plug and Play is a networking
architecture developed by a consortium
of companies to ensure easy connectivity
between products from different vendors.
UPnP devices should be able to connect to a
network automatically, handling identification
and other processes on the fly. The standards
developed by the UPnP Forum are media-,
platform-, and device-independent.
V
VBR (variable bit rate)
With VBR, the encoder takes as much bits
as it needs. So black pictures get few bits and
complex pictures get as much as they need.
While this provides the best quality the final
size cannot be predicted at all.
