What is Internet?

The system of inter-connected computers on a global scale, is called the Internet.

How Internet was developed?

Let's dive into the history of Second World War!

The Cold War was going on between the United States and the Soviet Union. The Soviet Union was successful in launching their first satellite, Sputnik - 1 in 1957 . The US Government, then, created ARPA (Advanced Research Project Agency). They wanted to have a system of communication to communicate between the other buildings of ARPA spread around the US, to have all the research papers in a centralized system. So, they created the ARPANET (Advanced Research Project Agency Network) which connected MIT (Massachusetts Institute of Technology), Stanford University, UCLA (University of California, Los Angeles) and University of Utah. They used TCP/IP (Transmission Control Protocol) protocol in the ARPANET. As time went by, more and more computers were connected. There was no way to automatically share the linked documents.

WWW (World Wide Web) to the rescue!

WWW (The World Wide Web) came up, which was developed by Timothy Berners-Lee. This project stored the documents and could be accessed across the web. Here's the world's first website. But, there was no search engines. Now, search engines have been developed. The Internet Society is responsible for maintaining the Internet.
