  • Q: What was the reason for the invention of the Internet?

    A: In response to a request from the United States Department of Defense, work began on a system that would enable computers to connect and share information between universities. The first successful connection between two locations was achieved in 1969 through a system called ARPAnet, often written as ARPANET, and is considered to be the predecessor of the modern Internet. The actual start of the U.S. government-supported development of the protocols and packet-switched systems required to share information across research centers began as early as 1962 and was in response to the first successful launch of an orbiting satellite, Sputnik, by the Soviet Union in 1957.
