That's a funny one. How deeply do you want to "know" the Internet. First off it's CAPS. After that we are on the road to "deep." Has lots of traffic like Spam. Has illegal sites. Like the Russians. Has lots and lots of spyware. Those are little files that get in your machine and freak you out. So that was just the surface of the Internet. To get really "deep" we have to well ask Tim Berners-Lee. He's about as "deep" as you can get.
