computer networking history

 Computer networking began in the late 1960s with the creation of ARPANET, the first packet-switched network funded by the US Department of Defense, officially connecting computers in 1969 . Key milestones included the development of TCP/IP in the 1970s, the adoption of Ethernet in the 1970s/80s, and the launch of the World Wide Web in the early 1990s, evolving from academic research to a global infrastructure.    Key Eras and Milestones: 1960s: Origins and ARPANET: The Cold War prompted the US Department of Defense to create a decentralized network for reliable communication. In 1969, ARPANET (Advanced Research Projects Agency Network) was created, introducing packet switching. 1970s: Protocols and Early Networks: Development of network protocols and early specialized networks like ALOHANET (wireless) and CYCLADES (France). In 1976, Bob Metcalfe invented Ethernet. 1980s: TCP/IP Standardization: In 1983, ARPANET officially switched to the TCP/IP (Transmission Control...
