Dark internet is the dark world of internet. The amount of data stored on the visible web is 500 times greater than that on the invisible web. Conventional internet search engines do not find it. Like the black hole mystery of the universe, the internet is also obsessed with the dark web mystery. Unmatched Internet as a database in the virtual world. The Internet is like an ocean of information. Numerous answers can be found by searching the search engine by typing the required words. Popular search engines include Google , Yahoo , Bing , AOL, etc. Google today is unrivaled in finding information on the Internet. However, these search engines can search how much information in the virtual world. The answer is , only 10 percent! So where is the remaining 90 percent of the data ? This vast chunk of virtual data is hidden in an invisible web called the Darkweb or the Blackweb or the Deepweb. Like the black hole mystery of the universe, the internet is also invaded by the invisible web mystery. According to a survey , 500 times more data is stored on the invisible web than is stored on the visible web. In fact, this invisible web is the size of the ocean and the visible internet is the equivalent of a piece of ice floating in the ocean! What is DeepWeb: DeepWeb is a part of the Internet that is not included in search engines. Search engines usually collect data with virtual robots or crawlers. These crawlers record the websites by looking at the HTML tags of the websites. In addition, some site authorities send requests to search engines to add their information. However, if the site authorities want, they can keep their data out of the reach of search engines. For this, the people concerned use the robot execution protocol. Some sites are dynamic, that is, it is possible to find the existence of such sites subject to certain conditions. In addition, search engines cannot find webpages in formats other than text [such as Flash format]. McPhee's security researcher Kejaya Munz says of the Darkweb that the Deepweb or Darkweb is made up of a lot of information that cannot be updated by search engines for technical reasons. Deepweb was launched in 1994 and was then known as Hidden Web. In 2001, it was renamed DeepWeb or DarkWeb. Darkweb is usually run in secret. Military forces , revolutionaries , hackers , and even state administrations use the Darkweb. Detectives are also seen secretly exchanging information or bargaining for stolen information. Many countries in the world have restrictions on internet usage. This is why dissidents often resort to the Darkweb.
