VNC is an acronym of Virtual Network Computing. You can use your Mac’s free VNC support to remotely connect and control your Mac over a network. You can even control your Mac remotely over the Internet.
In Mac OS X 10.5, aka Tiger, Apple introduced Screen Sharing to the Finder. While Screen Sharing appears to be built on VNC, it uses a more sophisticated authentication process that stops most generic VNC clients connecting.
To start a general VNC server on your Mac you need to click a few check boxes.
