If you never heard of it before, you come to the right place, because i will tell you what is a deep web and how to access it.
Deep Web also known as the Deepnet, Invisible Web or Hidden Web is the portion of World Wide Web content that is not indexed by standard search engines.
there is a lot of information on the net but most of the Web’s information is buried far down on sites, and standard search engines do not find it. Google or yahoo were unable to indexed this site because it hidden deep in the net, the traditional search engines cannot see or retrieve content in the deep Web. The portion of the Web that is indexed by standard search engines is known as the Surface Web. As of 2001, the deep Web was several orders of magnitude larger than the surface Web.
The expert estimated the size of this deep web is 7.9 zettabytes but no one can really sure how large this deep web is, because the content are added everyday and frequently.
The deep web should not be confused with the dark Internet, computers that can no longer be reached via the Internet. The Darknet distributed file sharing network, can be classified as part of the Deep Web.
