U

:
unshielded twisted pair

V

:
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.
:
visual display unit
:
A graphic image drawn in shapes and lines, called paths.
:

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.

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

Computer Science Of or relating to the production of images on video displays.
:
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.
:
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.

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.

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 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
