How does the INTERNET works?

Introduction

Have you ever thought about who runs the internet? Who controls the internet worldwide? Maybe you could think that internet provider companies like Jio, Airtel, and BSNL control the internet. But this isn't true because if one company stops providing it, other companies are present. Then, you'd think maybe our government controls it, but that isn't true either. At most, the government can remove 2-3 Facebook posts or block websites. But these can be bypassed easily and this does not amount to control over the internet worldwide.

Major Internet Companies

Then, you could think that companies like Google, Facebook, and YouTube control it because they have the largest data. But that isn't true either because you can build a website of your own and these companies would not be able to interfere in it. So, the question is when you are building a website of your own, who is providing you with the space to create the website on the Internet? Is there a website that can tell you which website you can build and which website you cannot?

Domain Names

The internet is an important innovation or you can say a tool which helps in maintaining freedom and democracy worldwide. Some countries keep their citizens blocked off completely from certain websites. Some websites like Google, YouTube, and Facebook are permanently blocked there because the Chinese government wants to brainwash its citizens in a particular way. Therefore, I think it's essential to understand how the Internet works and what it is. There is a URL/link to www.youtube.com. "YouTube" here, is called a domain name and the ".com" is called the top-level domain. If you want to build your website, then you will have to buy your domain name from websites that sell domain names, like GoDaddy.com.

The Role of ICANN

Now the question is, who gave GoDaddy the authority to sell domain names? Who is GoDaddy to sell domain names? There must be someone who gives assent to GoDaddy to sell domain names. And if there's no one, then GoDaddy has become the boss of the internet in a way. That is, it would be the one to sell domain names as well as decide who can own which website. But this isn't so. There is another authority above it. The name of this authority is ICANN, the Internet Corporation for Assigned Names and Numbers (ICANN). This is a non-profit organization based in Los Angeles. You could say that this is the top-level authority regarding the Internet. It has the power to authorize which websites can sell domain names. There could be .com, .in, .info, or .gov. All of this is decided by ICANN. For example, we may make a website with .gov in its name. We may build domain names with .com in it.

Structure of the Internet

ICANN sells top-level domain names to the rest of the companies by bidding. The companies that it sells to are called "registries". Below the registries are the registrars. Companies like GoDaddy.com can sell both top-level domains as well as domain names to the people. So, is ICANN the God of the internet? This cannot be said because the internet is a very decentralized network. All the mobile phones and computers that are connected to the internet make up the internet providers. You could call it a "server". Your mobile phones and computers are data centres and servers that are connected through wires. Huge underwater cables have been laid worldwide across the continents that connect the computers worldwide to one another which make up the internet.

Mobile Internet

How do the networks work? Mobile phones operate through mobile towers and offer 3G and 4G, which do not have an extremely wide range. Your mobile phones have the 3G/4G signal only when you are close to the mobile towers. But if you move a little further away, then the signals on your phone won't show up. So, the towers of mobile phones are connected to wires and they are eventually connected to those wires that are connected to the wires connected worldwide. So, in a way, you could say that the company that has laid down these wires holds a huge amount of significant power because it is supplying Comcast Xfinity Internet's best broadband deals to many different places.

Internet Service Providers (ISPs)

The companies lay down cables on land to help the optimum internet near me reach every household by connecting these wires to the main cable and connecting your computers to the internet worldwide. They too hold a huge amount of significant power. They are called Internet service providers (ISPs). These would be companies like Airtel, Jio, Att fibre internet, Starlink internet and BSNL that supply Tmobile home internet/Verizon home internet. And yes, they do hold significant power because these ISPs can block certain websites upon the direction of the Government if the Government says so. However, they do not hold sufficient powers to control a lot of things because you could use VPNs to overcome the blockages of the ISPs.

IP Addresses and Internet

Just like every mobile phone has a number from which you can call another mobile phone, similarly, every device that is connected to the internet has an IP address. Be it your computer, your smartphone, or any other server like a data centre, if it's connected to the spectrum internet, it will have an IP address. Each website too has an IP address. Humans cannot read IP addresses because it is written in digits and numbers. So, the domain name is a human-readable form of an IP address. When you type the domain name of a website in your browser, then the thing that converts the domain name into the IP address is called the Domain Name Server (DNS). Sometimes the Internet Service Providers block certain websites from the DNS so that when you type the domain name, it is not able to link it to the particular IP address. So, the DNS of the Internet Service Providers blocks you from reaching certain websites.

Conclusion

So, let us revert to our original question: How does the internet work step by step? How does the internet work simple explanation? How does the web work? Who controls the Internet? Whom does it belong to? The correct answer to this would be that it belongs to nobody and belongs to everybody because the internet runs only when it is a decentralized system. And if you wish to buy a part of the internet, if you wish to own it, you can only do it when you build a website of your own.
