What was the Internet's original name?

The original name of the Internet was ARPANET. This network was developed in the late 1960s by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense. It was initially designed to facilitate communication and resource sharing among academic and military researchers. ARPANET is considered the precursor to the modern Internet, as it was the first packet-switching network and introduced many concepts that would become fundamental to the Internet's architecture.

As ARPANET evolved and expanded, it laid the groundwork for what we now know as the Internet. The transition from ARPANET to the Internet included the development of new protocols and standards, particularly the TCP/IP protocol suite, which became the foundation for the modern digital communications we rely on today. This historical significance is key to understanding the evolution of networking technologies and the Internet's development.
