What is Deep web?

World Wide Web (WWW)

World wide web is simple called the web which is visible to all by simple regular browser like chrome. It is also can be said that it is visible web to all. You have seen that mostly sites (url) have sites name with www at first which denote world wide web. But don't make any sense that only sites with www is a sites in World wide web. Site name (url) with http or https at first are also the part of WWW. When you type any sites link with www, http or https or not also , it will first check the web directory that is domain name. Domain server return the IP address for this sites and browser will search the sites with IP address. There is only a URL with same name/character so we don't need to write www, http or https. Domain server will check the URL and return the IP address and browser will search and display the output. So only the register URL or register domain can be shown by regular browser. I think you know about WWW and how regular browser works.

Deep web

Do you know about deep web? Simply, it is a world wide web which is not visible to all or can't be access by any unauthorized person but can be searched through any regular browser like google chrome, opera, Firefox etc. You can say that deep web is also world wide web. But one thing is that it is not shown in regular browser, I mean, these sites are not index by any search engine. In general, deep web is a parts of world wide web which is not visible for all. It can be also called invisible web or hidden web. Some people says that deep web and dark web is same. But it is not. Dark web is not just hidden web , it is encrypted web and can't be access by regular browser. It need to a standard browser to access this web by TorBrowser. You can visit my blog about TorBrowser HERE.

From this figure you can easily find different between world wide web, deep web and dark web. The URL/sites which is visible to all is world wide web. Such websites which is used regularly by us like google, amazon, Facebook, Wikipedia etc all are in world wide web. You may get supersized when you know this all websites/URL are just about 4% of total sites/ total web. Most of all sites are hidden in deep web and dark web. Is not it interesting?

    Now you have a question about that google know everything, Wikipedia has all information, Facebook has most people information, all people everyday use these type of world wide web, how can it just 4% of total web? Let you know all things in detail. In hidden web/ deep web, it is the collection of net banking, research paper,  medical record, hidden wiki, private network, private forms etc. The data which is stored by government is also located in deep web.  No any bank want to show their private data to all so that they can make good service and prevent hacker to steal their data. Same as the government also store their data to hide and make it safe form anyone. Like that many more sites/people/group do it to make all data safe and not to give access to all. If one want to access this data, one should know about ID and password. It is too hard to find the location or sites first and too much hard to crack it. Not only these type of data, All sites which is not registered in domain directory are in deep web. So many people make website and they don't want to publish it, so this link will be very hard to know to search engine or these links are hidden to any search engine. Some people publish websites, make hidden data that not to index on search engine or they prevent to index it by code. These hidden data sites also are in deep web. In this way, deep web has big data collection than world wide web. We will discuss about dark web and why deep web sites is not index by search engine in details.
