By 1971, Ray Tomlinson sent the first network email and introduced the "@" symbol. By 1973, ARPANET became international, connecting nodes in Norway and the UK. 3. The Invention of TCP/IP (1970s–1983)
In the early 1960s, researchers like Leonard Kleinrock , Paul Baran , and Donald Davies independently developed "packet switching". This method breaks data into small "packets" that can take different routes to a destination and reassemble upon arrival, making networks more resilient than traditional telephone lines. 2. ARPANET: The Precursor (1969) internet creation
After the Soviet Union launched Sputnik 1, the U.S. government established the Advanced Research Projects Agency (ARPA) in 1958 to ensure American technological superiority. By 1971, Ray Tomlinson sent the first network
ARPANET, the first real prototype of the internet, was launched by ARPA to allow researchers at different universities to share computer resources. The Invention of TCP/IP (1970s–1983) In the early
The creation of the internet was not a single "eureka" moment but a decades-long evolution involving government agencies, academic researchers, and visionary computer scientists. It transitioned from a Cold War-era military project into the global, commercial network we use today. 1. The Seeds of Connectivity (1950s–1960s)
On October 29, 1969, the first message was sent between UCLA and the Stanford Research Institute (SRI) . The intended message was "LOGIN," but the system crashed after the first two letters, making "LO" the first data ever transmitted over the network.
The journey began in the late 1950s, catalyzed by the Cold War.
