Can I still install and use Ubuntu without any basic knowledge of a Linux operating system - do I need any background knowledge of Linux to use Ubuntu? If so, what will be the limits of my experience?

Also, I heard from http://www.whylinuxisbetter.net/ that I don't need any drivers for hardware and peripherals. Can somebody shed some light on this statement?

P.S. I don't know if these questions have been asked yet, I searched for these (maybe I didn't search hard enough), but I didn't find any.
