The World of Internet – How It All Began
The Internet that we know today was not always like this. In fact, it was not even designed to disseminate this article to you. Its communication protocol (the IP system) was not originally meant to bring you on this page.
Internet Was ARPAnet
The origins of the internet dates to the period when the US and the Soviet Union were locked in the Cold War. US scientists and military experts were concerned about a “what might be” scenario:
What might happen in the event that Soviet army attacked the country’s telephone system? How would they be able to maintain efficient long distance communication?
It was this worry, that necessitated the design of an alternative communication system.
In 1962, a scientist named J.C.R Licklider, working at ARPA (Department of Defense’s Advanced Research Projects Agency) proposed a solution in the form of talking computers—machines that would be able to communicate with each other via a galactic network. The idea if successfully deployed, would then enable US government leaders to talk to each other, even if the telephone system were to be destroyed.
Three years later, in 1965, the idea became a reality. A way of sending information from one computer to another was finally developed. The method was called “packet switching” and the established network came to be known as the ARPAnet.
“LO” – The First Message Sent Over the ARPAnet
A computer located at the UCLA research lab was connected with another computer at Stanford, through ARPAnet. The sent message read, “LOGIN”. But before the complete message could be delivered, ARPAnet came crashing down. Only the first two letters of the word were sent and received successfully — “LO”.
ARPAnet Expands and Internet is Born
What initially started as a network of two computers, slowly expanded into four. During 1970s, ARPAnet expanded further, inducting University College of London and Royal Radar Establishment (Norway).
It was the first time ARPAnet went global. However, there was a problem:
The ARPAnet was not robust enough to integrate the world’s mini networks within its own network.
It had expanded—but only by a little.
The communication protocol system had to be redesigned to accommodate more networks. Vinton Cerf, a computer scientist, came up with a novel technology, called Transmission Control Protocol. The ARPAnet could now go global. The term “Internet” was coined.
ARPAnet became the Internet
Further refinement was needed in the communication protocol technology, and Cerf added another module to Transmission Control Protocol – the “Internet Protocol”.
Internet Still a Medium of Communication
Despite all these developments, the internet was still being used as a medium of communication. It wasn’t used as a source of information.
Throughout the 1980s, scientists and researchers used internet to send file from one computer to another.
The Advent of World Wide Web – The Modern Day Internet
DNS was established and with DNS came the advent of world wide web – the internet of today. This was the year 1991, and from there on it evolved and is still evolving.
That is how it all began:
The need to communicate during wartime…
And the rest is history!
