History of Internet-All About Internet that You Must Know

The Internet has joined the whole world, from which a revolutionary era of exchange of information has begun. Here, I am going to tell you all the important knowledge about origin of Internet, its functionality and answers to all your questions related to Internet.

How the Internet was invented?

The Internet was invented due to the cold war. In the 1960s and 1970s, there was a threat of nuclear bomb on both Russia and the United States. If an atom bomb was attacked, then the exchange of messages would end and you can not send any secret message. America had already thought of these threats. So they thought of creating a methodology that connects one computer to another computer with an underground cable so that message can  be easily delivered to computers. America did not plan to make a main center of it so that if any part of the this network ceased to work, the rest of the networks would work. Pentagon's ARPA (Advanced Research Projects Agency) was appointed to create this network. 

American Researcher and ARPA together created a network, which was initially called ARPANET and the American computers were added to it. By the year 1990 the Cold War had almost ended and the danger of nuclear bomb was also deferred. Therefore, ARPANET Technology was handed over to the National Science Foundation by the US Government and later it was known as INTERNET. 

There was neither a domain nor a website in the 1990's as the computers were connected by LAN. In ARPANET, we needed to know which computer contains data, then we could get that data. But Tim Berners-Lee solved this problem in 1991 by inventing WWW (World Wide Web). After sometime, the WWW became the international network and all domains are being registered with this name. 

Who is the Owner of the Internet?

There is no owner of the Internet. Or in other words, the person using it, is the owner of it. It was invented in the public sector in the United States which used money from American Defense and Research University. After this AM, FM radio and TV were invented by money of US government and gave it for public use. After this, many small ISPs (Internet Service Provider) started in the world, who combined their local network to the global Internet. In this way, the network of INTERNET spread to the whole world.

How we get information from the Internet so quickly?

Let's understand the functionality of the Internet through an example. Suppose you searched the official website of Knowledge "The Gosai" by typing The Gosai. Then this command will first reach Local Service Provider and then the Router Computer Network of your city. After this, it will be transported to Google.com. After this, Google would find the data of The Gosai website from its database and the data would be transferred to you by reverse method. All these processes are approximated by the speed of light, so any data is reach us within a few seconds. 

How big is Internet traffic?

We can not even imagine. However, if we talk about data, more than 8 lakh kilometers of fabric optics cables are lying in the bottom of the ocean and also millions of kilometers of cable are underground. According to Google, there are more than a thousand billion Webpages in its Databases and their number is increasing every day. More than 5 lakh new Webpages are being created every 5 minutes in the world.

Internet is free but why are we asked for money?

The functionality of the Internet is free to us, but there are three types of servers in the world that provide us the Internet- Tier 1, Tier 2, Tier 3.

Tier 1 companies are those who had laid the entire network of fiber optics cable inside the Sea. Tier 2 are locals companies who lay cables underground in their own countries. Tier 3 companies are our Local Service Providers.  In spite of being free, they take the money to lay these cables and for their maintenance. 

When did Internet start in India?

Internet was started in India on August 15, 1995 when private company BSNL launched it. After this, private companies such as Reliance, Docomo, Airtel also started it.
