How did the Internet come about?

Find out how the internet came about, the global computer network that has become an important part of the daily life of many people in many parts of the world.

The Internet was born on January 1, 1983, the day known as Flag Day, which is the time when the TCP / IP protocol replaced the previous standard – called NCP – and became an agreement from ARPANET, the forerunner of the network we have today. However, his first step happened many years ago, around 1960.

During the Cold War, both the United States and the former Soviet Union experimented and believed in the power of communication. The US military doesn’t want their data to fall into the wrong hands, so they need a way to store everything on the network. With this goal, the national research organization ARPA – which stands for Advanced Research Projects Agency – created ARPANET as the first model that would be the basis of the internet.

According to the law, the first message sent by ARPANET was the word “LOGIN” and this happened on October 29, 1969, from a computer at the University of California to another at Stanford University. Interestingly, each computer is the size of a small house and only the letters “L” and “O” make it through before the machines crash.

Peace helped create the internet

In the 1970s, with the end of the Cold War, the world entered a period of so-called “Peaceful Coexistence” between the United States and the Soviet Union. Because there is no idea of ​​immediate and direct attack on the countries, the North American government has allowed many researchers to work with ARPANET.

So, the researchers Robert Kahn and Vinton Cerf created a communication model that would be based on the data to be transmitted through various networks, this process is called TCP / IP (a abbreviation in English for communication control/internet protocol) and adopted by ARPANET. So, the internet officially came to this world.

Who invented the internet?

There is no single name considered the inventor of the internet, but a group of scientists, engineers and programmers who have worked on the project from the idea to the birth.

It is worth remembering that the inventor Nikola Tesla had the idea of ​​a universal, wireless system in the early 1900s. Around 1960, psychologist and computer scientist Joseph Carl Robnett Licklider developed the concept of a computer network for communication.

When did the internet arrive in Brazil?

The Internet as we know it today did not appear in Brazil anytime soon, but its first opportunity appeared in 1988 to connect Brazilian universities with universities in the United States.

The first national service similar to the internet is Alternex from the Brazilian Ministry of Health and Economy (Ibase). Although there is a focus on providing non-academic and non-governmental services, only members and partners of the organization can use the product.

Finally, in 1992, Alternex was opened to the public and, in May 1995, internet banking finally took place in Brazil.

Today, it seems that we do not know how to live without the internet, because it is still possible to make money with it. However, have you ever thought about what would happen if the internet disappeared for good?
