Video and data conferencing
Video and data conferencing lets you see and speak to a customer anywhere in the world, work on documents together, present your products or discuss new ideas. It can save fares and travel time, improve customer relationships, allow quicker decision making and cut time to market.

Virus
A chunk of computer programming code that makes copies of itself without any conscious human intervention. Some viruses do more than simply replicate themselves, they might display messages, install other software or files, delete software of files, etc.

A virus requires the presence of some other program to replicate itself. Typically viruses spread by attaching themselves to programs and in some cases files, for example the file formats for Microsoft word processor and spreadsheet programs allow the inclusion of programs called “macros” which can in some cases be a breeding ground for viruses.

Visitors
The number of people arriving at your website. Can be measured over an hour, day, week, month, etc.
