The Internet was born in 1969, in the United States, originally interconnected research laboratories and was called ARPAnet (ARPA: Advanced Research Projects Agency). It was a network of the US Department of Defense. It was the height of the cold war, and scientists wanted a net that would remain standing in the event of a bombing.
Then came the central concept of the internet: it is a network in which all points are equivalent and there is no central command. Thus, if B stops working, A and C continue to be able to communicate.
The name internet itself came much later, when ARPAnet's technology began to be used to connect universities and laboratories, first in the US and then in other countries.
Therefore, there is no single center that "governs" the internet. Today it is a collection of over 40,000 networks worldwide. What these networks have in common is the TCP / IP (Transmission Control Protocol / internet protocol) protocol, which allows them to communicate with each other. These protocols are the common language of computers that integrate the Internet.
So the internet can be defined as:
A network of networks based on the TCP / IP protocol; a community of people who use and develop such networks; a collection of resources that can be achieved through these networks. For about two decades the internet was restricted to the academic and scientific environment.
In 1987 for the first time its commercial use in the United States was released. More was in 1992 that the network became fashionable. A number of internet service provider companies began appearing in the US. Hundreds of thousands of people started putting information on the internet, which has become a worldwide craze.
In Brazil the commercial exploitation of the internet was liberated in 1995. Today, the Internet Steering Committee evaluates the number of users in the country by one million (November / 97 data). A good address to find out more about the history of the internet is InterNIC.
