What is the Virtual Cockpit on my Audi A4?

I've heard that the Audi A4 comes with a Virtual Cockpit, but I'm not sure what that means or how it works. Can someone explain it to me?

The Virtual Cockpit on an Audi A4 is a fully digital instrument cluster that displays all of your vehicle's information in one customizable screen.

I love the Virtual Cockpit on my A4 - it's so convenient to have all of my pertinent driving information right in front of me.

Instead of traditional gauges, the Virtual Cockpit uses high-resolution screens to display speed, fuel levels, and other vehicle data.
