'LOGIN'
On October 29, 1969, Arpanet delivered its first message: a “node-to-node” communication from one computer to another. (The first computer was located in a research lab at UCLA and the second was at Stanford; each one was the size of a large room.) The message—“LOGIN”—was short and simple, but it crashed the fledgling Arpanet anyway: The Stanford computer only received the note’s first two letters.
