VNC is remote control software which allows you to view and fully interact with one computer desktop (the "VNC server") using a simple program (the "VNC viewer") on another computer desktop anywhere on the Internet. The two computers don't even have to be the same type, so for example you can use VNC to view a Windows Vista desktop at the office on a Linux or Mac computer at home. For ultimate simplicity, there is even a Java viewer, so that any desktop can be controlled remotely from within a browser without having to install software.
VNC has a wide range of applications including system administration, IT support and helpdesks. It can also be used to support the mobile user, both for hot desking within the enterprise and also to provide remote access at home, or on the road. The system allows several connections to the same desktop, providing an invaluable tool for collaborative or shared working in the workplace or classroom. Computer support within the geographically spread family is an ever popular use.
For the individual user, one common scenario is using VNC to help troubleshoot the computer of a distant less-technically-savvy relative. In other words, sitting at your desk in Baltimore, you could use VNC to take control of your relative's PC in California and show them how to install and use some new software package by actually doing it yourself.
