Definition - What does Intergalactic Computer Network mean?
The Intergalactic Computer Network is a name that Joseph Carl Robnett Licklider gave to a conceptual network in a memo. The memo, and Licklider himself, inspired the creation of ARPANET, a network that eventually evolved into a system that is now the modern-day Internet.
Licklider may have been using the name as a joke, but the joke caught on. For much of the 1960s, the idea of a worldwide Internet was often called a Galactic Network. Like another early term, Internauts, the Intergalactic Computer Network has largely fallen out of regular usage.
