RealVNC

VNC stands for Virtual Network Computing. It is remote control software which allows you to view and interact with one computer (the server ) using a simple program (the viewer ) on another computer anywhere on the Internet. The two computers dont even have to be the same type, so for example you can use VNC to view an office Linux machine on your Windows PC at home. VNC is freely and publicly available and is in widespread active use by millions throughout industry, academia and privately. This version includes both the VNC server and viewer.

VNC is widely used in educational contexts, for example to allow a distributed group of students simultaneously to view a computer screen being manipulated by an instructor, or to allow the instructor to take control of the students computers to provide assistance.

A very common business application of VNC is in remote system administration, where it is used to allow administrators to take control of employee machines to diagnose and fix problems, or to access and administer server machines without making a trip to the console. VNC can also be used to provide a flexible hot-desking and road-warrior environment by allowing employees to access their office desktop and server machines from any machine in the company's offices or from other remote sites, regardless of the type of computers involved at either end.
