Basically there are 3 stages of the internet ,they will be explained below only for educational purposes .
There is a big section of the internet that you will rarely be able to use in your life , today i will tell you about that section which we can call hidden internet section or hidden web.
first of all we will talk about the "Surface Web".
1. Surface Web:
Surface Web is the web which we use in our daily life, means that everyone in the world watching youtube videos , reading blogs , searching google etc. is using the surface web. Basically Surface web is the web in which we search for information ,entertainment,knowledge etc. plus facebook , twitter , google+ etc. they are all part of surface web. This can be accessed without any special permission and you can get almost all the information of a surface web with a google search. torrents and downloading software and media are also part of this surface web. And the main fact is that all this surface web part consists of only 4% - 5% of all the web.


2. Deep Web:
So what is the deep web?, all the online cloud storage like google drive or drop box or the research work of a university or important files of company , databases of banks or databases of governments etc. which are saved online and are not publicly available for use and can not be accessed by a google search is known as deep web. If you want to access deep web you want a special URL or special web address with a special server and of course the permission to access that data and also all the content of deep web is not indexed in google search or any other search engine so whether you are searching you can not access data which is present in my google drive because it is the part of deep web. It is useful because we have to store large amount of data online and then share it with people but selected people so in this case we can send that special URL through which one can access the particular data.
3. Dark Web:
Disclaimer : Dark Web is completely illegal and this small amount of information is just about educational purposes.
This is the part of the web through which almost anything can be done or accessed like trading in black market or trades of drugs or trading of arms etc. Basically in this part of the web you can do anything at any time but its completely illegal and you can into trouble for this. Also this kind of stuff will not be available through google search. If you want to use dark web then you have to download special browsers like "tor" or the onion router but its completely illegal and should be used at any cost because all the black market content is present . Initially it was invented for US Navy but today it is widely used, it is also used as a VPN.
