Advanced Research Projects Agency Network (ARPANET)

The Advanced Research Projects Agency Network (ARPANET) was a pioneering network developed in the late 1960s by the U.S. Department of Defense. It connected various universities and research institutions, allowing them to share information and resources through computers. ARPANET introduced key technologies like packet switching, which breaks data into smaller pieces for efficient transmission. This network laid the groundwork for the modern Internet, demonstrating how computers could communicate over long distances. Its success highlighted the potential of interconnected systems, fundamentally changing how information is shared and accessed globally.
