The Deep Web
Deep Web exists beneath the surface and cannot be accessed by standard search engines, this makes it very mysterious and only a few people actually know how the Deep Web works. Studies show that the portal consists of 7.5 petabytes, though this number continues to grow exponentially. While the Surface Internet is immense, Deep Web is even bigger and estimated to be around 500 times greater than it. This despite the fact that very little is known about its operations.
A large portion of this platform is innocuous, consisting of inaccessible content sections such as libraries, corporate intranets, academic research archives and databases which conventional browsers can’t access. Similarly, the Deep Web has password protected private sites requiring registration and login, as well as encrypted networks, unlinked content and web archives that can’t be indexed and hence undiscoverable by online directories such as Google.
It makes up approximately 96% of all Internet content which means that what we see is only 4%, even so lots of people still continue using it since it’s a very rich source of data. At least half of the content stored here can be found in topic-specific catalogs, 95% of which can be accessed by approved members of the public and not subject to charges or subscription fees. Some of the most popular Deep Web sites include NASA EOSDIS, National Climatic Data Centre, and even MP3.com.
Nevertheless, most dark web (a small portion of the Deep Web) sites can only be accessed through Tor network. This is an anonymity “Onion Router” designed for keeping the user’s identity and physical location undetectable when browsing through
