The Birth of the Internet and ARPANET
The birth of the Internet traces back to the late 1960s with the development of ARPANET, a project funded by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA). ARPANET enabled multiple computers to communicate on a single network, pioneering packet-switching technology. This innovation laid the foundation for global connectivity, eventually evolving into the modern Internet, revolutionizing communication, information sharing, and the digital landscape worldwide.
