W
: Also known as: Watt Watt (W) is the standard
unit for measuring power, and it indicates the rate at which energy
- for example electrical or electromagnetic energy - is radiated,
absorbed, or dissipated. One Watt is equivalent to using one Joule
of energy per second. The RF and audio power available from a
mobile phone will determine its capacity to provide good signal
strength, which is necessary in order to maintain satisfactory
communications with users on the phone network. There has to be a
compromise however, as the higher the power used by the phone, then
the greater will be the drain on its battery. The power can be
determined by calculating the product of the voltage and the
current (i.e. Watts = Volts x Amps). |

Wallpaper
: Wallpaper is a picture or graphical image that
fully covers the display screen of a computer, mobile phone or
other equipment with a visual monitor. This 'wallpaper' is used to
customise the background environment on the user's screen, and to
give the equipment a personalised or corporate appearance.
Wallpaper is available for free download from many websites,
although there are also specialist companies that sell designer
wallpaper |

WAP
: wireless application protocol |

WAP Identity Module
: Also known as: WIM WIM (WAP identity module)
is a security module that provides a more secure environment when
using WAP related applications and services on a mobile device via
a WAP gateway. A WIM allows the user to store certificates and
digital signatures |

Wavelength
: Wavelength is the physical distance spanned by
one complete cycle or wave of an alternating signal as it travels
through space. The term wavelength can be applied to many types of
wave, e.g. audio, radio, light, etc, but is generally only
applicable to a wave of a single frequency, such as the RF carrier
transmitted by a mobile phone. Wavelength (l), usually measured in
metres between the adjacent peaks or troughs of consecutive waves,
is related to frequency (f) and propagation velocity (v) by the
equation l = v / f. Note that the propagation velocity depends on
the type of wave and the material through which it passes: radio
waves travel at the speed of light, but audio waves at the speed of
sound |

Web authoring software
: A computer programme designed to produce web
pages for a web site. |
|
Web Page
: A web page or webpage is a
resource on the World Wide Web |
|
Web site Web pages
: A collection of related pages (web pages) of
information, owned and maintained by the same organisation or
individual, and published on the Internet. It is relatively
straightforward for schools and individuals to create a web
site. |
|
Whiteboard/interactive, electronic
: Like a conventional whiteboard, except that
the images from the computer are projected onto the board and can
be controlled and adjusted on screen using a stylus. Can be used in
whole class teaching. |

Wireless Application Protocol
: Also known as: WAP WAP (Wireless Application
Protocol) is a common global standard, which defines the way in
which Internet communications and advanced non-voice services are
provided on wireless mobile devices, such as digital mobile phones
and Personal Digital Assistants. The current version of this
protocol is WAP 2.0, and it is fast becoming the standard way for
mobile devices to access Internet services, by communicating with a
server installed in the mobile phone network. A mobile device can
therefore combine telephony services with the limited capacity of
mobile terminal displays, and so provide the user with a
microbrowser. A WAP enabled phone provides interactive access to
the Internet, and to services such as online news and information,
e-commerce transactions, online banking, e-mail messaging, Internet
Relay Chat (IRC), and a host of new services still in development.
Subscribers use WAP to access websites and pages that have been
converted for WML (Wireless Markup Language), which are stripped
down to their basic text format, and this is more suitable for the
limited display capabilities of mobile devices. WAP works with
multiple standards and is supported by most modern mobile networks,
such as GSM, GPRS, and UMTS, and in the future equipment and
networks that use WAP will be more compatible, regardless of the
manufacturer. WAP is the mobile equivalent of HTTP (HyperText
Transfer Protocol), and has been developed through the cooperation
of the world's major telecommunications and software companies,
their activities being co-ordinated through the WAP Forum. The WAP
Forum has a website at www.wapforum.org. Some manufacturers claim
that their handsets have WAP 2.0 browsers; this is often a
re-branding of an XHTML-MP browser, the version number representing
XHTML replacing WML for mobile content markup. An alternative
system standard to WAP is i-Mode |

Wireless Phone
: Wireless Phone is another name for a mobile
phone. The word 'wireless' refers to the fact that the phone is
actually a small radio transceiver, which communicates with the
mobile telephone network by transmitting and receiving radio
signals through the air without using wires. Although the various
types of mobile phone, cell (cellular) phones, and car phones are
all wireless devices, the cordless phones used at home are not
considered wireless, as their base units are connected by wires to
the network |

Word processing
: The ability to enter, edit, manipulate, store
and print pages of text using a computer. Modern word processors
have desktop publishing capability. |
|
World Wide Web
: The vast collection of information which has
been published on the Internet in the form of web pages. |
|
Wristwatch monitor
: This consists of a strap fitting around your
chest that contains a radio that transmits your heartbeat to a
wristwatch monitor. Heart monitors can be programmed to beep if
your pulse rate moves outside your target zone. |
