Virtual Corporations
This concept can cover a number of possibilities, but the core concept is that company employees can be located anywhere in the world. One possibility is for a small business to develop, advertise, distribute, and support without the need for any office space.

Another example would be an attempt to gain competitive advantages by splitting a project among teams spread around locations with different time zones. The developers could write code in one team and go home at the end of the day, enabling another team to start working and debug the code. Finally, a third team in a different location could test the various modules together.

Virtual Memory
Hard disk space which can be used as additional memory for holding data not immediately required by the processor.

Virus
Just like your body, your computer can get a virus and be invaded with a virus making you (or your computer) sick. A virus can wipe out information on your computer and create major havoc. Viruses usually originate from malicious people. You can unintentionally download virus from a web site or get it from a disk that someone has lent you. There are virus-checking programs, but there are new viruses popping up every day. So the best defense against a virus is to be very careful not to download programs or data from a site you're not familiar with.

VPN
A Virtual Private Network (VPN) consists of a limited number of computers owned by a single enterprise that share information specifically with each other. A VPN uses the Internet as the transport backbone to make secure links between such entities as business partners, main and regional offices, or vendors and suppliers in a supply chain. It is called virtual because it depends on the use of virtual, or temporary, connections that have no real physical presence but consist of packets routed over various machines on the Internet on an ad hoc basis.
