It's both the central node but it's also your active render context. What happens when you want to quickly render another texture in the background and use it as a mask, displacement map, or material texture? In this case, Render To Texture node comes to the rescue. It allows you to build a completely separate scene that gets rendered off screen and you can use that output of it just like any other texture in Notch.
