The **Virtual Network Computing** (**VNC**) is a graphical [desktop sharing](http://en.wikipedia.org/wiki/Desktop_sharing"Desktop sharing") system that uses the [Remote Frame Buffer protocol (RFB)](http://en.wikipedia.org/wiki/RFB_protocol"RFB protocol") to remotely control another [computer](http://en.wikipedia.org/wiki/Computer"Computer"). It transmits the [keyboard](http://en.wikipedia.org/wiki/Computer_keyboard"Computer keyboard") and [mouse](http://en.wikipedia.org/wiki/Computer_mouse") events from one computer to another, relaying the graphical [screen](http://en.wikipedia.org/wiki/Computer_screen"Computer screen") updates back in the other direction, over a [network](http://en.wikipedia.org/wiki/Computer_network"Computer network").
Vnc-based connections are faster (require less network bandwidth) then [X11](x-window-system) applications forwarded directly through ssh.
The recommended clients are [TightVNC](http://www.tightvnc.com) or [TigerVNC](http://sourceforge.net/apps/mediawiki/tigervnc/index.php?title=Main_Page)(free, open source, available for almost any platform).
