Packet-switched network, digital network that transfers data files by breaking them up into smaller units (“packets”) and transmitting them through a series of nodes (“switches”). In a process known as store-and-forward, the switches route the packets to their destination, where the data files are then reassembled.

The concept of packet switching was pioneered independently by Paul Baran at the RAND Corporation and Donald Davies in the early 1960s, with the first practical implementation being the ARPANET (Advanced Research Projects Agency Network), which is considered the precursor to the modern internet, developed in the late 1960s under the leadership of Larry Roberts and utilizing research from Leonard Kleinrock at UCLA; essentially, the ARPANET marked the first operational packet-switched network, enabling data to be broken into smaller packets and sent across various routes for efficient transmission across a network

The Advanced Research Projects Agency Network (ARPANET) was a pioneering computer network that was the precursor to the modern internet: 

• Development

• The U.S. Department of Defense's Advanced Research Projects Agency (ARPA) funded the development of ARPANET in the late 1960s. The first routers were built in 1968 by BBN Technologies.

It was first used in 1969 and finally decommissioned in 1989. ARPANET's main use was for academic and research purposes. Many of the protocols used by computer networks today were developed for ARPANET, and it is considered the forerunner of the modern internet.

TCP is the component that collects and reassembles the packets of data, while IP is responsible for making sure the packets are sent to the right destination. TCP/IP was developed in the 1970s and adopted as the protocol standard for ARPANET (the predecessor to the Internet) in 1983

Robert E. Kahn. Robert Kahn and Vinton Cerf created the architecture for the Internet and collaborated on the design of software known as the Transmission Control Protocol/Internet Protocol, or TCP/IP that implements the architecture.
