ARPANET links research computers through packet switching
ARPANET’s early nodes shared computing resources through packet switching, creating an important experimental foundation for later internetworking.

The story
In 1969, ARPANET connected institutions including UCLA and the Stanford Research Institute, reaching four nodes by year’s end. An October remote-login attempt failed after only part of the message arrived, illustrating the practical work still required. ARPA, BBN and university teams contributed. This was not the completion of today’s internet in a single day: packet switching, internetwork protocols and the later Web were distinct developments.
Connections and context
Packets allowed devices to share communication links. Common protocols later connected different networks; the Web would organize linked documents on top of the internet rather than replace it.
