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)
ARPANET, the first real prototype of the internet, was launched by ARPA to allow researchers at different universities to share computer resources.
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)
They developed TCP/IP (Transmission Control Protocol/Internet Protocol). TCP handles data assembly/disassembly, while IP ensures packets reach the correct address.
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 January 1, 1983, ARPANET officially switched to TCP/IP. This "network of networks" approach is what technically defined the birth of the "Internet". The Internet | Johan Norberg's New and Improved
As more independent networks emerged, they were often incompatible. and Bob Kahn , often called the "Fathers of the Internet," solved this by designing a universal language.
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.
