The term Deep Internet (also known as the Invisible Internet and the Dark Net) refers to the hidden web content not indexed by standard search engines. Some estimates are that the Deep Internet is 500 times bigger than the surface Web (the visible Net). Feel of the surface web as the surface of the ocean-miles and miles of surface out there, as far as the eye can see. But when you cast a net, it goes beneath the surface and captures issues unseen to the eye.
