The correct full form of ARPANET is
Advanced Research Projects Agency Network. ARPANET was a pioneering project funded by the U.S. Department of Defense to connect computers at different universities and research institutions, which eventually evolved into what we know today as the internet. ARPANET was instrumental in developing key technologies such as packet switching and the TCP/IP protocol, which form the foundation of modern internet communication.
Important Key Points:
1.
Foundation of the Internet: ARPANET is often considered the precursor to the modern internet.
2.
Packet Switching: It introduced the concept of packet switching, a method of data transmission that divides data into packets and sends them independently to their destination.
3.
US Department of Defense: ARPANET was funded and initially managed by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA), which later became DARPA.
4.
Evolution into the Internet: Over time, ARPANET grew, and its protocols were adopted globally, leading to the development of the internet.
5.
Influence on Networking: ARPANET laid the groundwork for the development of networking technologies, including the adoption of TCP/IP.
