What is the precursor to the Internet, ARPANET?
The Fifth-Generation Computer Project did not meet its goal by 1991 and was completed; this story was known only in Japan, but the United States faced a similar situation. By the late 1980s, the Defense Advanced Research Projects Agency (DARPA), which conducts technology development research for the Department of Defense, had already stopped funding AI. The reason was that expectations were not high.
DARPA, which had operated briefly under the name ARPA, kept that name widely known in the world. “ARPANET” existed as a precursor network to the Internet.
ARPANET was a network system that became the Internet’s predecessor. It was a vast network covering universities and research institutes across the United States funded by ARPA, and it served as a field for demonstration research itself. It began on October 29, 1969, with a login attempt from UCLA to Stanford University, and by 1973 it covered the United States (Figure ①).

As the basis for data communication, instead of circuit-switched networks that monopolize channels for each communication like telephone calls, a technology called “packet switching” was implemented. Information is divided into fixed chunks and transmitted, and the packets are reassembled at the destination, allowing multiple users to share dedicated lines simultaneously.
