VNC (Virtual Network Computing) 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 don't even have to be the same type, so for example you can use it to view an office Linux machine on your Windows PC at home. It is freely and publicly available and is in widespread active use by millions throughout industry, academia and privately.
