This “public” part of the internet is merely the surface of what is available on the internet. Tens of trillions, a number you cannot imagine, web pages populate the internet and most people will never see those “other” pages on the “invisible web”. They are mostly made up of boring statistics, data base information, and, of course, anything illegal you can imagine. The drawing above gives you an idea of what makes up the huge portion of the internet. But the deep web is not necessarily bad: your password protected Gmail messages live there, so do many other password protected sites.
Alas, there is an underbelly of the Deep Web called the “Dark Web”. The “dark web” should never be confused with the Deep Web. You may never want to visit there, but you really should know what it is all about. Specifically, the dark web is a collection of publicly visible websites that hide their IP addresses of servers that host them. Any of these sites can be visited by any web user but you cannot find these sites using the “surface” web search engine. Almost all of the sites on the dark web use the Tor encryption tool to hide their identity. You need to use the Tor browser to take you to those places on the dark web. The browser runs on a relay system that bounces signals around to different Tor-enabled computers all over the world.
