This is achieved by sending mouse movements and key-presses to the remote computer, and replicating the remote computer's display (subject to differences in resolution) locally in real time. UltraVNC allows the use of a remote computer as if the user were in front of it. It uses the VNC protocol to control/access another computer remotely over a network connection. The client supports Microsoft Windows and Linux but the server only supports Windows. UltraVNC (sometimes written uVNC) is an open-source remote-administration/ remote-desktop-software utility.
