The Internet is the global system of interconnected computer networks that use the Internet Protocol Suite (TCP / IP) to connect devices around the world. The internet is part of our lives, and it's hard to imagine our day-to-day life without this feature. However, many people are unaware of how the Internet came about. Today, we revisit some of the history of the internet.

Like many other technological advances, the Internet arises in the course of World War II and the establishment of the Cold War. The need to create secure communication channels has fostered the development of tools and codes that allowed the circulation of information among the military.

In 1957, the Soviet Union launched Sputnik 1 and 2 satellites and, in response, the US Department of Defense created the Advanced Research Projects Agency (ARPA). ARPA aimed to develop a tool capable of allowing communication between US military bases in case the Pentagon is hit by a nuclear attack. Thus, in 1969 ArpaNet appears.

However, in the 1970s the first personal computers began to emerge, which were practically not used by civil society, but in companies, in academia, among others. Universities and other institutions have had access to Arpanet since the 1970s and have allowed access to universities outside the United States, thereby creating the foundation for a worldwide computer network. In the 1980s, ArpaNet disengaged itself from military forces, integrating with other existing academic networks (NSFNET, CSNET, etc.) giving rise to what we now call the internet.

In 1989 comes the World Wide Web (www), created by Tim Berners-Lee, as an information integrator that allows simple and consistent access to different platforms.

Since then, the Internet has enabled citizens to end new forms of social interaction, activities and access to knowledge, shaping the way we communicate, consume audiovisual content, locate information, etc.

It is very difficult to imagine the functioning of society as we know it today without the Internet because even the smallest tasks of daily life nowadays pass through this network that connects us to the rest of the world.
