Finally, as computer networks expanded, the need arose to establish a standard communication protocol that would allow the interconnection of all existing networks. In 1983, the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol was implemented, which would become the universal standard for communication on the Internet. This protocol allowed the transfer of data efficiently and reliable, which fueled the growth and popularity of the Internet worldwide.
2. The key protagonists in the emergence of the internet
In the emergence of the Internet, there were various key protagonists who played a fundamental role in the development of this revolutionary technology. Among them are researchers, companies and organizations that contributed with their work and vision to make the creation of the network of networks possible.
One of the main actors The emergence of the Internet was the United States government, through the initiative of the Advanced Research Projects Agency (ARPA). This agency, created in 1958, had as its main objective to develop technologies that strengthen the security of the United States. It was in this context that the ARPA-NET project, considered the precursor of the Internet, was carried out.
Another key protagonist in the emergence of the Internet was the British scientist Tim Berners-Lee, who is recognized as the inventor of the World Wide Web. In 1989, Berners-Lee proposed an information management system based on hypertext that allowed information to be accessed and shared globally. This idea materialized with the creation of the first site and the launch of the first browser in 1990, laying the foundations for the expansion and popularization of the Internet.
3. The evolution of communication technologies prior to the internet
It has been fundamental to understanding how this global network of interconnection emerged. From the first developments of telegraph and telephone systems to the creation of television and radio, each technological advance has laid the foundation for the emergence of the Internet. The evolution of these technologies has allowed the transmission of information and data over long distances, paving the way for the emergence of a network that would connect people around the world.
One of the most important milestones in the evolution of communication technologies was the development of ARPANET in the 60s by the United States Department of Defense. The main objective of this project was to create a robust and decentralized communication network that could resist even in the event of attacks or catastrophes. ARPANET laid the foundations for the TCP/IP protocol, which became the communication standard on the Internet and allowed the interconnection of various networks. in only one.
Another fundamental aspect was the development of satellite communication systems. These systems allowed the transmission of data and communication signals over long distances without the need for cables or terrestrial infrastructure. This was a crucial advance in the construction of a global communication network, since it allowed remote regions to be connected and geographical limitations to be overcome for the transmission of information.
4. The birth of ARPANET: the precursor of the world wide web
The birth of ARPANET marked the beginning of what we know today as the Internet. It was developed in the 1960s by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. This pioneering project had as its main objective to establish a secure and decentralized communication network that could resist failures in the event of attacks or natural disasters.. This innovative solution consisted of dividing the information into small data packets and sending them through various paths, which guaranteed the robustness and redundancy of the network.
The ARPANET was based on a technology called packet switching, where data is divided into more manageable sections and sent separately. This revolutionary methodology allowed for efficient and fast long-distance communication, something never seen before.. In addition, ARPANET also introduced the concept of a network of networks, initially connecting four computer nodes in different geographic locations.
