Computer Networks - I — Question 2

ARPAnet (Advanced Research Projects Agency NETwork) is regarded as the first computer network. It was started by the U.S. Department of Defense in 1969 with the goal of connecting the computers at different universities and U.S. defense. It laid the foundations of today's internet.

NSFnet was the high-capacity network started by the National Science Foundation which was more capable than ARPAnet. NSFnet allowed only academic research on its network and not any kind of private business on it.
