Where Internet Was Invented: The ARPANET Story
In 1969, computer scientist Leonard Kleinrock at the University of California, Los Angeles (UCLA) had an idea that would change the world. It was so big that it couldn’t be contained on one campus, and so Kleinrock began pitching his idea to researchers at other universities across the country on the phone, no less until he finally convinced them to join him in creating what would become the ARPANET, the precursor to today’s Internet. This article tells you where the internet was invented.
The Advanced Research Projects Agency Network (ARPANET)
The first step in the invention of the internet was to create a packet-switching network that could connect computers with each other. It started with the U.S. Department of Defense Advanced Research Projects Agency Network (ARPANET). They commissioned a team to work on designing this new type of network, which led to the creation of one specific network called NCP and then finally, TCP/IP. These new technologies became the basis for what we know as today’s internet. In 1968, people from all over gathered at UCLA for a conference on computer communication networks. This conference would have a profound effect on how our modern world communicates because it showcased many ideas for networking such as a distributed operating system that let different kinds of machines process information without being controlled by just one central computer.
As you can see, so much was created by just one conference! The next thing they needed to do was find an efficient way of sending data through the new network. So, Larry Roberts proposed using links between different nodes where packets were broken up into smaller blocks and transmitted separately but simultaneously. Robert Woltman, who later went on to found Usenet, thought they should use message buffers instead because this would result in more efficient utilization of resources but he never won the debate. Later when Usenet appeared, Robert had them use message buffers instead but this is another story for another time. But enough about what happened afterward let us go back in time again and learn about where the internet was invented.
The Origins of the ARPANET
The National Science Foundation (NSF) created the Advanced Research Projects Agency (ARPA) in 1957. More than a decade later, the NSF funded the development of an experimental network between three universities. Over time, this network grew to become the ARPANET. This first packet-switching computer network was used for text-based communication and eventually led to the world wide web. There are many versions of where the internet was invented. Most people think that it happened during World War II. Others say that it happened in 1973 when the United States Department of Defense created the Arpanet.
But most experts think that there were two different beginnings for what we now call the internet. Some people believe that its origins go back to 1943 when Vannevar Bush developed his idea for something he called Memex. Other people believe that its origins go back to 1965 when Leonard Kleinrock designed a way for computers to talk with one another over long distances by sending messages through cables at high speeds and low costs – thus creating the packet system we know today as packet switching.
Where Internet Was Invented: The Birth of the Internet
The history of the internet begins with the development of electronic computers in the 1950s. A handful of computer scientists, including J.C.R. Licklider, were instrumental in developing early ideas about networking computers, but it wasn’t until 1969 that the first computer network was built. Referred to as the ARPANET, this ground-breaking project connected a handful of computers at universities and research labs across America for experimental purposes. It was never intended to be more than an experimental program, but it sparked a revolution in communications and led directly to the invention of what we now know as the internet.
In 1974, two researchers at Stanford University named Larry Roberts and Bob Kahn began work on a protocol called TCP/IP (Transmission Control Protocol / Internet Protocol) designed to unify disparate networks into one larger network of networks. The first use of the technology came on January 1, 1983, when three TCP/IP networks—two in California and one in Utah began sending information to each other via dial-up connections.
Where Internet Was Invented: The Evolution of the Internet
In the late 1960s, a computer scientist at the United States Department of Defense named Robert Taylor proposed an idea for how the country could survive a nuclear war. He suggested that a network of computers be set up so that, even if some parts were damaged, others could still connect to one another and share information. This idea became known as the computer utility, and it laid the groundwork for what would eventually become the internet. Taylor hired Lawrence Roberts to design this system, which was called the Advanced Research Projects Agency Network (ARPANET). Roberts started by building four nodes two in California and two in Utah connected by telephone lines.
On October 29th, 1969, he successfully sent data from one computer to another on this system for the first time. The next step involved connecting other networks to ARPANET using phone cables, microwave radio, satellite links, or fiber-optic cables. It wasn’t until 1988 that the final step occurred: completing the world’s largest public packet-switching network. By 1989 there were over 100,000 hosts on more than 50 networks around the world linked together via this giant system of interconnected networks that we call the internet.
The internet has become an integral part of our lives. It’s now woven into everything we do, and it’s hard to imagine life without it. But the history of the internet goes back much further than you may realize. One of the first experiments with what would later become the internet took place in 1969 when an American computer scientist named Leonard Kleinrock sent data between two nodes, or computers, over a distance of 45 feet using a packet-switching network that he had helped create called the ARPANET.
The development of the ARPANET was a project funded by the Department of Defense Advanced Research Projects Agency (ARPA), which was looking for a way to make it easier for its different branches to communicate with one another across long distances.
