How the internet works

You ever asked yourself from where the Internet comes. a difficult question??
I'll tell you today from where it  comes.
Let's start.
Internet is a global network of computers linked to each other and which are used to connect this vast amount
of digital pages and that we call the (World Wide Web).

It is a very large system of cables which travels across the world to reach our machines  to servers which
reserves  pages that we want to access.

But the question here is how does it work?
First, your device needs to connect to the Internet through your service provider through router.

Now when you enter the address of the site that you want to visit it sends  e-request for information over
a telephone line or your phone cables to the ISP (internet service provider).

Then the ISP  sends the site to the DNS address.

Now the DNS look for the address you entered, and when it finds a request sent it to the server, which hosts
the site.


This server can be somewhere else in the world and the request must   travels through the cables, which
are under the sea or underground until it reaches its destination.

These cables connect the world's continents to the Internet.

Except Antarctica

These cables are not thick and strong enough making them vulnerable to shark bites.

So if you have a slow internet connection you must to blame an hungry shark who eat a cables ^^.

But this is not a problem when this happens the process is done again, but exhibits another route for
that
 the Internet never stops.

And finally  the request arrived in  to the server that hosts the site.

The server retransmit the site data in the form of small pieces of data called packets.

That  the computer re-assembled to show you the site as you see on your computer screen.

All this happens in the blink of an eye, and such requests occur millions of times per second.
