The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet.

Feb 25, 2025 · ARPANET was an end-product of a decade of computer-communications developments spurred by military concerns that the Soviets might use their jet bombers to launch surprise nuclear attacks against the United States.

Feb 8, 2024 · Explore the journey of ARPANET, the pioneering project that laid the groundwork for today's Internet, in this detailed historical account.

ARPA research played a central role in launching the “Information Revolution,” including developing or furthering much of the conceptual basis for ARPANET, a pioneering network for sharing digital resources among geographically separated computers.

Sep 24, 2018 · Designed as a computer version of the nuclear bomb shelter, ARPAnet protected the flow of information between military installations by creating a network of geographically separated computers that could exchange information via a newly developed technology called NCP or Network Control Protocol.

After the ARPANET was functioning, the computer scientists using it realized that assisting human communication was a major fundamental advance that the ARPANET made possible.

ARPANET is the oldest and most influential merger of computer networks which contributed to the birth of the Internet. Learn more about the ARPANET system.

Nov 19, 2023 · What exactly was ARPANet? In short, ARPANet was the world‘s first operational packet switching computer network. It laid the foundations for modern computer networking and led directly to the creation of the Internet.

Dec 6, 2024 · ARPANET was created to make it easier for people to access computers, improve computer equipment, and to have a more effective communication method for the military.

In its earliest form, ARPANET began with four computer nodes in late 1969. Over the next two decades, DARPA-funded researchers expanded ARPANET and designed internet protocols — like transmission control protocol/internet protocol (TCP/IP) — allowing computers to transmit and receive data such as email, computer-to-computer file transfer ...
