What is the virtual cockpit in an Audi A8 and how does it work?

I've heard about the virtual cockpit in the Audi A8 but I'm not sure exactly what it is and how it functions. Can someone provide a detailed explanation?

The virtual cockpit in the Audi A8 is a fully digital instrument cluster that replaces traditional physical gauges with a high-resolution 12.3-inch display. It can be customized to display a variety of information, including navigation, vehicle diagnostics, and media controls. It also has the ability to display full-screen Google Earth and Street View maps.
