Who discovered the internet? When was the Internet invented, why?

Who discovered the internet

Although the World Wide Web was initially invented by one person, many individuals and groups attempted to originate the Internet. Its birth takes us back to the extremely competitive era of technology between the US and the USSR during the Cold War.

The Soviet Union sent the Sputnik 1 satellite into space on October 4, 1957. Partly in response to this, the US government created the Advanced Research Project Agency in 1958, today known as the DARPA-Defense Defense Advanced Research Projects Agency. The specific mission of this agency was to stop the technology of launching the Sputnik 1 satellite.

To coordinate such efforts, a fast way was needed to exchange data between various universities and laboratories. For this, J. C. R. Licklider created the "Intergalactic Computer Network" for the theoretical basis of the Internet. His idea was to create a network where many different computer systems would connect with each other in such a way that they would be able to quickly exchange data.

The idea of ​​ARPANET (Advanced Research Projects Agency Network) was born from Lawrence G. Roberts's 1966 publication "Towards a Cooperative Network of Time-Shared Computers".

In January 1969, the Advanced Research Projects Agency of the Department of Defense (ARPA) awarded a contract to Bolt, Beranek and Newman (BBN) to design and build a communication network.

In late 1969, ARPANT connected four nodes in California Los Angeles (UCLA), University of California at Santa Barbara (UCSB), Utah University and Stanford Research Institute (SRI).

The first use of this network occurred at 10:30 pm on 29, 1969 and was a communication between UCLA and the Stanford Research Institute.

With the threat of nuclear war, it was necessary to decentralize a system in which communication between all other computers could still occur if a node was destroyed. American engineer Paul Baran provided a solution to the issue; They designed a decentralized network that used packet switching to send and receive data.

Many others contributed to the development of an efficient packet switching system, including Leonard Kleinrock and Donald Davis. If you are not familiar with "packet switching", it basically breaks all transmitted data into appropriate-sized blocks, called packets. These packets are sent through a different route to the destination.
