How does internet work and who controls it ??
Internet has been the most important tool that is a daily need for for all of us. Every person whether it be a child or an adult ,whether it be a rich or a poor, Internet has become like a life partner.Some might even live without spouses but they cant live without internet.
But ever wondered who controls it. How does it work.? Lets find out.
So firstly speaking of how internet works, Lemme give a glimpse of what internet is.
The Internet is a vast network that connects computers, and may devices all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection.
If i put it in simple words, Internet helps us to communicate and share our happiness, our melancholy , our business work, Getting products delivered right on our doorstep, and also getting food 🍕🍔we love without leaving our home or comfort place.
Now you might wonder that who controls this internet. Is it the government, Is it the tele- communication providers. Or is it the domain and hosting providers like go-daddy or namecheap etc.Well ,thats not the case.
Now the question that must be striking your mind would be who gives the liscense or the authority to these hosting providers like go-daddy as i mentioned before to sell domain names.
There is an authority over these and its called ICANN.
The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions. These services were originally performed under U.S. Government contract by the Internet Assigned Numbers Authority (IANA) and other entities. ICANN now performs the IANA function.
Now you must be thinking OKAY! but what is its role?
ICANN is responsible for coordinating the management of the technical elements of the DNS to ensure universal resolvability so that all users of the Internet can find all valid addresses. It does this by overseeing the distribution of unique technical identifiers used in the Internet’s operations, and delegation of Top-Level Domain names (such as .com, .info, etc.).
Other issues of concern to Internet users, such as the rules for financial transactions, Internet content control, unsolicited commercial email (spam), and data protection are outside the range of ICANN’s mission of technical coordination.
ICANN sells these domains to companies with the help of bidding and the company which is being sold these domains are called as registries.And then we have registrars like go-daddy etc who can sell these domains futher.
So this means that ICANN is the godfather of internet. Thats not the case.
Internet is a very decentralized network just like a net. Each and every device which is connected to the internet is responsible for building it . Our mobiles,laptops and other gadgets out there are kind of a data-centre or we can say a server which are connected to each other through wires.
Huge under-water cables have been laid down world wide across the continents which helps in connecting our computers and making up the internet.
Now as i spoke you must be thinking that mobiles dont have any wires how are they connected.
Mobile phones works basically with the help of mobile towers we have seen.
The 3g/4g doesnt have a much high range. Thats why we have seen multiple towers near our houses. These towers are eventually connected to the wires which as i mentioned is connected to the wires which are being laid across the globe.
Imagine a big wire coming and then distributing to different areas of a country.
The company which laid down the wires and giving you the internet and other services and charge a particular amount for the service like airtel,jio etc, These companies are known as ISPs(Internet Service Providers). They hold a significant power of blocking some amount of sites or servers as ordered by the government but as Indians we find a way.
Now you must have heard of IP address.The address which the hacker or the protagonist of the movie uses to track the villain and beat the shit out of him.
Just like every mobile has a phone number and it needs other’s phone number to call to, like that every device connected to the internet has an IP address. Every website has an IP address too. Just like we call our friends by dailing their number, Similarly when we write an IP address in the search bar we get the desired info. Now you must be wondering that we write domain name like google, youtube etc?
Every domain name is connected to its IP address just like we people have an address.
IP addresses are for computers and domain names are for us to understand where we are heading. Its like japanese is for people in Japan and Hindi is a language for Indians.
These Domain names are converted into the IP addresses with the help of DNS means (Domain-Name-Server).
Now when sometimes we heard that this or that website is banned means that is blocked from the DNS.
Now in that case we have multiple solutions like either using a public DNS like of google or we could make use of VPN which most of us do .
If you want a part of internet , you need to own a website and after building a website you need to have a domain name for it and a server to host your website over it.
Now you must be confused as i said that previously i said that our mobiles and other devices are also kind of servers. Well, These devices dont have enough space or storage to keep your website.
If you want your website to run 24/7, you need to make that device work 24/7 after all to make your website available always.
But to deal with that problem we have AWS which pretty much solves this problem.
After that you need to link your domain name to your server and publish you DNS.
I think you pretty much understand that internet doesnt belong to anybody and belong to everybody.
In other words, we can say that Internet is a really huge and necessary tool we have today which gives us access to lots and lots of info, tutorials, platforms to express ourselves and also the opportunity to make your presence and rise.
Hope you now got the idea what is internet and its working etc.
