VNC consists of two types of component. A server, which generates a display, and a viewer, which actually draws the display on your screen. There are two important features of VNC:
The server and the viewer may be on different machines and on different architectures. We expect the most common use to be the display of a Unix X desktop on a PC, for example. The protocol which connects the server and viewer is simple, open, and platform- independent.

No state is stored at the viewer. Breaking the viewer's connection to the server and then reconnecting will not result in any loss of data. Because the connection can be remade from somewhere else, you have easy mobility.

So, to get started with VNC you need to run a server, and then connect to it with a viewer. Get the packages for the platforms you use from the download page, if you haven't already, and install them. The current VNC software requires a TCP/IP connection between the server and the viewer, though there is no reason why the software couldn't be modified to use, for example, RS232 or Firewire. We have internal versions that use other network transport layers. But for now you'll need to know the name or the IP address of the server machine.
Most people will be running either a Unix server or a Windows server, though similar principles will apply to other platforms
