The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control.
ARPANET was created in 1969 to connect scientific and research users across multiple institutions for collaboration and was one of the first networks to implement the TCP/IP protocol suite.
