How the internet works 

The Internet is the backbone of the Web, the technical infrastructure that makes the Web possible. At its most basic, the Internet is a large network of computers which communicate all together. The Internet
works because open standards allow every network to connect to every other network. This is what makes it possible for anyone to create content, offer services, and sell products without requiring permission from a central authority. It levels the playing field for everyone and it’s the reason why we have a rich diversity of applications and services that many of us enjoy today.
