How did the Department of Defense invent the Internet?

The Department of Defense did not invent the internet, but it played a crucial role in its development. In the 1960s, the Defense Advanced Research Projects Agency (DARPA) funded research that led to the creation of ARPANET, the first network to use packet switching technology. This project connected various research institutions, enabling them to share resources and information effectively. Over time, ARPANET evolved and laid the groundwork for the modern Internet we know today.
