DARK NET | DARK WEB | DEEP WEB | SURFACE WEB Darknet, dark web, deep web, surface web, what are all these terms? Don’t worry. I’ll explain them one by one and also tell you how the darknet is key to our privacy. Starting with the surface web, it is the web which is completely indexed by the search engines. Like, if you can access the internet, you can access the surface web. For instance right now while you are watching my video on youtube you are accessing the surface web. Now coming to the deep web, it constitutes of the 96% of the online content, the remaining 4% is the surface web.

Have you ever wondered why this Rubik's Cube which is often considered as a children's toy fascinates the mathematicians too? Surely because there is too much mathematics involved in it. What if you take a Rubik's cube and separate every piece of it and then you close your eyes and start assembling it again in any preferred configuration. When you take the first corner piece you'll have 8 possible positions of putting it as there are a total of 8 corner pieces in the cube. Then for the second piece, you'll have 7 possible positions as one position has already been occupied by the first piece you have put. Now, for the third piece, you'll have 6 possible positions and so on until for the last piece you'll have only one position left. So when you multiply them it becomes 8x7x6x5x4x3x2x1 or rather simply 8! . And each piece can be arranged in 3 possible orientations, it gives us 3^8 possibilities for each permutation of the corner pieces. Now coming to the e...
