In the early 1960s, a group of visionaries anticipated the very idea of ​​the Internet, and soon after the Cold War, the United States Department of Defense (DOD) began to realize the incredible potential value that will come from a control center system that protects the flow of information in the event of nuclear attacks by establishing a network of geographically distributed computers and sharing data. Then, they funded the Advanced Research Project Agency (APRA) to start a project (Bellis, 2011). APRA proceeded with the idea as a military experiment. Meanwhile, at CERN (Centre Europeen de Recherche Nucleaire) in Switzerland, an academic proposal has been made for a technology that will enable collaboration in the physics community to link research institutes and universities, allowing scientists to share files and academic studies resources (Gribble, 2011). The development of the Internet had to cover many revolutionary milestones, transforming it from a simple package of protocols into a comprehensive global information operational platform. The spotlight is on the beginnings of ARPANET, HTML (Hypertext Mark-up Language) technology and the birth of the WWW (World Wide Web) at CERN, up to the development of the Internet at the end of the 20th century. On September 2, 1969, six weeks after Armstrong landed on the Moon, the first test of the ARPANET between 2 computers exchanging data took place at the University of California (Hauben, 2009). The system crashed during the experiment, but with the demonstration of a theoretical vision a revolution began. In his article, Griffiths illustrates the first computer network connecting UCLA, Stanford Research Institute, University of California Santa Barbara and University of Utah “...... middle of paper ......df/downloads/pr/ teachers -notes/9781405880138.pdfGribble, C.
