Who discovered the internet?

Many people contributed to the discovery of the Internet. Leonard Kleinrock first planned to equip the US Defense Department with a new technology during the Cold War in 1957. Under this plan, many computers were to be connected and information were to be carried from one place to another. So that the soldiers can get the necessary information very easily.

In 1969, ARPANET (ADVANCE RESEARCH PROJECT AGENCY Network) was created so that any computer could be connected to any computer.

By the time of the 1980s, its name became the Internet. Vinton Cerf and Robert Kahn invented TCP/IP. Together they published a paper in 1974. The name was “The Fathers of the Internet”. Vint Cerf is called the father of the Internet because of publishing this research paper.

History of the Internet

In 1969, the University of California and the University of Utah in Los Angeles started the ARPANET (Advanced Research Projects Agency Network). The main goal of this project was to connect the computers of various colleges, schools and the US Defense Ministry among themselves. It was the world’s first packet switching network.

In the mid-80s, another federal agency, the National Science Foundation, created a new high-capacity network, the NSFnet, which was more capable than the ARPANET. The only drawback in NSFnet was that it allowed only educational research on its network, no private business of any kind was allowed. For this reason, private organizations and people started building their own networks, after which the Internet was formed by joining ARPANET and NSFnet.
