Internet. What it is?
It is not a secret that most of the technologies developed by man, which we enjoy today, had its origins in the studies and research that many countries were at some point in the middle of the fight for military supremacy. Internet is no exception to this rule.
It all began in 1962, with a project sponsored by the United States Department of Defense in conjunction with the University of California, Los Angeles, in which was established the initial network of the project. It was baptized with the name of Arpanet (Advanced Research Projects Agency Network), i.e., the network of the Agency’s projects of advanced research.
It was not until 1981 that one of the teams of the project initiation the term Internet, on the basis of the Interconnected Networks expression.
In 1989 the Arpanet project was replaced and liberate for commercial use the concept of interconnected networks that, with the birth in 1990 of the WWW or World Wide Web (global computer network), gave way to what we know today as the Internet:
A network that interconnects millions of networks around the world, and by which flow, in all senses, packets of Digital information with content that is interpreted and put into “readable” form by the browsers of all computers connected to this Network of Networks.
Once understood this very simplified history and definition of Internet, delving into its operation and its possibilities of use.
