UTP
: unshielded twisted pair |
|
V
Variable
: In a case-sensitive programming language,
variable names that differ only in case (book and
Book ) are considered different from each other.
Therefore the variable needs to remain consistent throughout the
programming in Flash. |
|
VDU
: visual display unit |
|
Vector Graphic
: A graphic image drawn in shapes and lines,
called paths. |
|
Vector Graphics
:
Vector graphics is the creation of digital images through a
sequence of commands or mathematical statements that place lines
and shapes in a given two-dimensional or three-dimensional space.

Vector Paths
: A vector path is made of a number of segments,
each of which is a connected sequence of points.

Video
: Computer Science Of or relating to the
production of images on video displays. |
|
Video capture
: Equipment which allows a video camera to be
connected to a computer. Video sequences or still images can then
be stored on disk and edited. |
|
Video conferencing
: By means of a camera and microphone attached
to each computer, several people can communicate at a distance with
sound and images, either via the Internet or high speed telephone
lines. |
|
Vinyl cutter
: A robotic cutting device that can be
programmed to cut vinyl to a pre-determined pattern. |
|
Virtual Teacher Centre
: Part of the National Grid for Learning, this
is a source of resource materials for the classroom, the library,
school management, career development, etc. |
|
Virus Protection
: A virus is a code which can either lie dormant
in a computer and be not particualry harmful, but it can can
also cause computers to shut down, lose of data, and even make the
computer need to be reformatted. To prevent this Virus Protection
has been created. There are many different programs for Virus
protection or Anti-virus software, some working better than others,
but the aim of all the programs is to protect your computer from
harmful and useless virus's. |
|
Voice conferencing
: Several people can communicate audibly at a
distance, either via the Internet, by means of a microphone
attached to each computer, or via ordinary telephone lines. |

W
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 |
