                        How does the Internet work?

A little, a lot, daily ... We are more and more to benefit from Internet access and we always spend more time there. But do we know how does the Internet works, basically? It is thanks to the Internet that you can enjoy this episode of Netflix.

Let's first remember that the Web is only part of the Internet. It is a service among others offered by the Internet, just like e-mail, instant messaging or file transfer. The Internet itself is a huge computer network, more specifically a network of networks.

Indeed, it connects millions of smaller computer networks, which can be public, private, corporate, academic or military networks. Each computer network allows computers to communicate with each other, to exchange data, in a binary language, consisting of bits with a value of 0 or 1. The Internet, as a global network, therefore aims to connect all the computers of the world. Now the Internet of Things, he wants to connect multiple machines, from cars to dishwashers to sensors mounted on floating tags in the ocean or wild animals.

Internet, a worldwide web of fiber optics and microwave links

An individual's computer connects to the ISP's router through a landline telephone line or wireless technology (Wi-Fi), which operates through radio waves. The router, which is also a computer, acts as an intermediary between the individual and the large computer centers around the world.

These data centers are interconnected, despite the long distances between them, by underground or submarine cables, generally fiber optic cables. These are lines where the information, coded in the light of a laser, transits at a rate of the order of a thousand billion bits per second. Without competing with such rapidity, access providers are gradually bringing the broadband Internet into homes by deploying fiber optics.

I hope you understand how internet work.
