What is the Internet?
Internet is a shortened term for 'inter-network'.
How does the internetwork?
The Internet is a global network of physical cables. This includes copper telephone wires, TV cables, and fiber optic cables. Wireless connections such as 3G / 4G and WiFi are also dependent on these physical networks for internet access.
When you visit any website, your computer sends the request to a server with the help of these wires. Servers are a place where all websites are stored. It acts like a computer hard drive. As soon as the request arrives, the server retrieves the website and retrieves the correct data ie information, or demand made to your internet to your computer. And you can see the result on your computer. The funny thing is that everything happens in the blink of an eye.
Uses of the Internet
With the use of the Internet, you can find any information of the world. Just like you are now learning about the Internet through the Internet. You can talk to anyone from any corner of the world. E-mail communications are one of the oldest ways of exchanging information with the Internet.

History of the Internet
After knowing so much, this question must have come in your mind that what is the history of such the internet? Who discovered it? So the father of the internet is 'Winton Gray Cerf'. However, some credit goes to 'Bob Kohno', who was the co-developer of TCP / IP.
The Internet was first discovered in 1969 through a network called ARPANET, in which several computers were communicated to one network at a time. The first webpage was created in 1991 after many years of development. In November 1992, the first internet website 'Snapshot of the CERN The World Wide Web Project' was announced.
When the Internet comes to India?
Internet services were launched in India by Videsh Sanchar Nigam Limited for the first time on 15 August 1995. And in November 1998, the government also opened the area to private operators.
How does internet work?
In today's day for all of us, the internet is a huge contribution. It is a gift but there are very few people to think about how it reduces and how it is made. How does it work? Read the entire post. In the friends, we can easily learn about the internet from the reports done by some Baiganikos.
The Internet is a worldwide network of computers which would be connected to telephone wires and satellite. If you want to understand it in an easy way, then you do it in 2 parts. The first server is all the information and all the information is shared with the other server.
And you humans can get this information from the same. The second part is the browser. If you use a browser to see whatever information is inside that server, for that you must have internet explore, google chrome, firefox Mozilla Whenever you connect your computer to the net, at the time you have your internet service provider like you connect the server with any telicominuaction company or any internet providing company,
which is called ham isp. And the server of that data service provider gets connected to the rest of the net with the help of your browser. There is a lot of browsers connect from one data service provider. The Internet service provider gets any request from everyone's browser like watching email, or Visiting a website, that server does not have any information, so that server gets connected to the rest of the server's data.
How is the internet made?
Now let's see how the internet is made?
As soon as we open any browser in mobile and type youtube.com in it and enter it across the internet, then this request goes to the data service provider and After that searches the server of youtube.com, we find that youtube's IP address is 216.58.194.174 which is in united state of America mountain view city. It takes information from it and sends it to our network service provider After that, our data service provider sends that information to our browser. And it is seen across our screen. This way we get to see videos across youtube.
Some people chat and call despite the phone's internet being turned off. Via mash networking. (Source - Reuters)
Protests are taking place across the country in protest against CAA. Section 144 is engaged in many places. The government has stopped the internet in many areas. People are having problems. Because the internet has become part of our daily diet. But the understanding of many of us about the Internet will be close to zero.
We have a very basic need behind the invention of the Internet. The name of that need is information.
Where did the basic information come from? The basic needs are bread, cloth, and a house?
Our breed (Homo sapiens) lives in cities and villages today. But our ancestors lived in the forest. Most of the time the development of the human mind has taken place in the forest itself. That's why our habits are still forest. To survive in the forest, each other's cooperation is required. And the basis of cooperation is information. Such as -
Where is the water? Where is the food In which area are dangerous animals roaming?
Human being is such a weak creature that even without cooperation, the victim cannot even learn to walk. (Source - Wikimedia)
Today we do not live in the forest, but we are still addicted to information. Due to this addiction, we gossip. Let's chat Do google Internet is the biggest means to do all this.
Internet means trap. Information web spread all over the world. Through this web, information reaches from one place to another. But where does the information come from? And how does it come?
Gangotri of information - data center
As postcards are gathered at the post office, digital information with the internet is collected in the data center. Data centers have many servers. Machines that are full of information. The server means the server. The machines that serve to provide information.
Many companies like Google, Microsoft, Facebook have built their data centers. India and China have the largest number of internet users in the world. But most of the data centers are in America and Europe. China, let's build our data center fast. But there are very few data centers in India. Most of India's data comes from outside.
How does data come from seven seas?
A satellite can be a way of getting data here, but the satellite is in space above. First he will receive the signal, then send it from there to somewhere else. In this, the signal will have to cover more distance and time will be much longer. And sending signals over long distances from the satellite is a messy task.
Roshni goes ahead, hitting an angle with the fiber. Therefore, the signal goes from the speed of light to less than the speed. (Source - Wikipedia)
Here optical fiber is used. The information is sent by making a light signal. At a very fast speed. Know one fact of GK ie General Knowledge -
The highest speed in the world is light. Around three million kilometers per second.
Optical fiber means the signal is sent to very thin tubes of glass. Data comes from data centers located abroad through fiber cables to their country.
Fiber cables are inserted with the help of the ship. (Source - Reuters)
There are many fiber cables laying in the sea. And their huge network connects all countries. Through these cables, that information comes to our country.
How does it know what information to send? Where else to send?
Just like our houses have a postal address, our machines also have an address. This address is called IP Address. Full name Internet Protocol Address. This IP address is a number.
Whenever you enter a website, the request reaches the server of that website. Request that the so-called information be sent to the Phalni information.
You may have seen IPv4 and IPv6 written. These are different versions of both IPs. IPv6 is the latest version.
The server also has an IP address. When you enter www.thelallantop.com, the machine reads the IP address of Lallantop's server.
Just as the names and numbers are written in the phonebook, there is a record of the website and their IP address. Its name is DNS i.e. Domain Name System. The machine requests the IP address of the server of that website according to DNS.
Information from the server of the website reaches your country through fiber cables laid in the sea. From here, pulses within the ground reach your city with fiber cables.
How this information will reach your home depends on the connection with which you are running the Internet. It is responsible for your ISP (Internet Service Provider). Internet service provider means the company that is providing you internet facility.
If you are running the internet through cable then the information will reach your machine through the power cable from the optical fiber.
The Internet connects to our system through this wire. There are copper wires inside it. More information becomes an electrical signal. (Source - Reuters)
If you are running the internet from mobile then the first information strolling in optical fiber will reach the tower near you. And your tower will take it to your mobile.
Information comes from the fiber cable from the bottom of the tower. And it sends information from above by creating an electromagnetic waves. (Source - Reuters)
Every information is sent in pieces from the server. These pieces are called data packets. If you have run slow internet then you must have noticed that the parts of the image are loaded one by one. This is because as soon as the pockets reach you, your machine starts to make that image. Image, audio, video, text - this happens with every data file.
It is exactly the same way that if we have to deliver something, then its pieces come. Then we add. (Source - Pixar)
In order to show the way to these packets (pieces) of information, many machines are started in between. These machines are named routers and switches. By sending routers and switches routed information from the server to your IP address. The pieces of this information are assembled in your machine and you get the whole roti (information).
Recap
A lot has happened once it is recap.
You entered www.gmail.com
The content of this website is placed in a server in a data center.
This server's address (IP Address) will be seen in the DNS name diary.
The request will reach the server through this address.
The request sent to the server will also have the IP address of your machine.
The server will send the information after seeing your address (IP Adress).
Information will come out from the server in pieces.
Routers and switches will show this information.
These servers may be across seven seas. From there, pieces of information will reach your country via fiber cables present in the sea.
From here to your city with fiber cables laid inside the ground.
From here your ISP (the company that has a net) will send it to the tower or house near you.
From here to your machine.
Data packets are assembled in the machine and website views on your screen.
