For example, if you come to this article by shearing your question “What is Internet?” in the web browser, then this information has also reached your Clint Computer/Mobile from a Sever Computer through the Internet.
- Like you watch a video in Youtube, that video also reaches your computer from a server computer through the Internet. To exchange all this information in the Internet, there are many protocols which are called Internet Protocol.
Just as there are some rules for doing all the work, in the same way some rules have been made for sending and receiving data / information from one computer to another computer which is called internet protocol, these protocols Through the Internet, information is sent and received in a secure and right place.

Internet was not invented at any one time and by any one scientist, it has been invented generation after generation with the cooperation of many scientists.
The Internet was first started in 1962 by the US Department of Defense, at this time America’s Defense Team wanted to create a wireless network through which all the computers of America’s Defense Team could connect to each other, no matter how far away that computer is. No “by this he wanted to transfer information rapidly from one place to another”
In 1962, a US computer scientist “J.C.R. Licklider” created an organization he named DARPA (Defense Advanced Research Projects Agency), through this organization he created a network, which he named Intergalactic Computer Network, its purpose was all of America’s defense systems. To connect computers to each other wirelessly so that they can send their secret messages or information from one place to another securely, fast and secretly
On October 9, 1969, DARPA attempted to send the world’s first message “Login” using this network to a computer at the Stanford Research Institute, 350 km from a computer at the University of California, but the Stanford Research Institute computer half the message “Lo Crashed just by sending “. Then later after some correction he is able to send this message.
Then in 1974, DARPA’s Chief Manager “Vint Cerf” and “Robert E. Kahn” designed TCP (Transmission Control Protocol) to connect two computers and send information correctly, which is still in use today.
Then on 1 January 1983, Vint Cerf and Robert E. Kahn created a unique ID for every computer, which is called IP Address, this made it easy to access the Internet in every computer and since then TCP has been used with IP. Then it was called TCP / IP, “TCP sends data / information and IP detects the address of the computer to which the information is to be sent.”
“Vint Cerf” and “Robert E. Kahn” are called Father of Internet
Then in 1983 itself, Paul Mockapetris invented domain names like .com, .in, .net, .gov etc. With the help of this, websites started being made by name, otherwise before going to any website, we had to remember its IP address (eg – 123.3.5.11.2)
Then in 1989 Vint Cerf and Robert created the world’s first ISP i.e. “Internet Service Provider Company”, which was named “Telnet”, by which common people were allowed to use the Internet, otherwise before 1989 the Internet was only America’s Defense System. , used to be in Government Agency and Research University only
Internet in India was first introduced on August 15, 1995 by Videsh Sanchar Nigam Limited (VSNL). Later the name of VSNL was changed to BSNL (Bharat Sanchar Nigam Limited).
After this, many private ISP (internet service provider companies) came into existence in India till date like Jio, Airtel, VI etc. through which we are able to access internet today.
