Hello friends, welcome to Infoseemedia. Today we discuss how does the internet work.
It’s difficult to imagine our lives without the internet nowadays. Have you ever wondered ➡
What the internet exactly is and how it works?
When I was young I believed that the internet was some magic trick created by a secret group of magicians which makes it float through the clouds. But when I came across its actual definition I understood that it is a network that connects millions of computers worldwide. But the important question still remains the same, how does this magic happen?
Imagine you and your friend want to share a feature or some other essential document with each other. To do so the first thing you both will need are computers that are connected in a network with the help of the Internet. Once you establish this connection you visit the website using a browser, login to your account, type your message, or attach the file you wish to send. Finally, when everything is done you press the send button. It’s gone. sounds easy right?
Well, what looked so easy at first glance has a complex system working behind it. Yes, my friends, the messages you send are actually enormous in size and it’s very hard for the internet to carry such a massive packet to its destination. So to make it easier this huge packet is broken down into smaller packages. Then they are moved further to the receiver with the help of an essential device called the Router.
What is a Router?
A Rooter is a networking device that helps in the transfer of data packets between computer networks. In other words from a sender to the receiver.
How?
Well, it does with the help of an Internet Protocol or an IP address.
What’s an IP address?
So many technical terms but let me explain. Just like you have your home address every server has its unique address called the IP address. This allows a system to be recognized by other systems connected via Internet Protocol.
When the packets are received by the Router, the Rooter reads the IP address information mentioned on the package. Then the router sends it to the correct path to reach its destination by following certain rules.
Like we have traffic rules to protect us from any accidents, the Internet has some rules and regulations as well called the TCP. TCP is a set of protocols developed for the Internet to get data from one network device to another. By following these protocols the data gets delivered in the best possible way to its destination without any problems and issues.
When these packets finally arrive at the receiver’s router, they are put together according to the instructions. That’s how your friend’s computer receives your message. Believe me, all this happens within just a fraction of seconds. Isn’t it really magical?
Did you know?
The first-ever email was sent in 1971.
It is estimated that 4 billion out of the 7 billion people on earth are already online.
