How the internet works

The internet. It is a important tool in our life and it make life much more convenient.
In the post, I will tell you how the internet works with a simply example.

You are going to share a image with you friends in Twitter. A lot of step had been done to make this happen but it just happens so quickly.

1. Your computer coverts the image to millions of packets. This step is called Packet switching.
2. The Packet travels from the server and this is how its done
3. It goes to the server you are using
4. Then it will go to the server of your city
5. Then it goes to your country's server
6. After that, it goes to server that has the twitter server in it
7. The packets reach twitter and it is sorted and put in order to make an image
