VNC (Virtual Network Computing) is a method for sharing a remote desktop environment. Allowing you to remote control another computer or server over the Internet or local network as if you were sitting in front of it. Keyboard and mouse strokes from your computer are relayed to the remote computer/server. There are many different kinds of VNC software available today. Several are cross-platform and add additional features, such as chat or file transfers. VNC is often used for remote technical support and remotely accessing files.
