How does ARPANET work?
Developed under U.S. Advanced Research Projects Agency, a Department of Defense agency, ARPANET uses packet-switch technology in order to send and receive data with built-in error correction and package assembly. ARPANET was the first design of what has become known as the Internet today.
How does ARPANET get internet?
On October 29, 1969, ARPAnet delivered its first message: a “node-to-node” communication from one computer to another. ARPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet.
What was the first computer message?
UCLA student Charley Kline attempts to transmit the text “login” to a computer at the Stanford Research Institute over the first link on the ARPANET, which was the precursor to the modern Internet. After the letters “l” and “o” are sent the system crashed, making the first message ever sent on the Internet “lo”.
