30 years of the Internet

While Sir Tim Berners-Lee is credited with the World Wide Web in 1989, the actual back-end technology that facilitated the Internet called Packet Transmission control protocol/ Internet Protocol (TCP) was adopted 30 years ago at the US Defense Advanced Research Projects Agency (DARPA) on January 1, 1983. Google called up Vint Cerf, who is considered to be one of the fathers of the Internet, as his work at DARPA along with Robert Kahn led to the creation of the Transmission control protocol.

The TCP protocol was based on packet switching communication. While other packet switching existed, the beauty of the TCP protocol was it was a common language and supported connections among different packet switched networks.

Later to support real time data better, TCP was split into two with other half being called the Internet Protocol and then both were combined which is now known as TCP/IP.

“Robert Kahn and I developed a new computer communication protocol designed specifically to support connection among different packet-switched networks,” Vint Cerf wrote in his post.

“We called it TCP, short for “Transmission Control Protocol,” and in 1974 we published a paper about it in IEEE Transactions on Communications: “A Protocol for Packet Network Intercommunication.” Later, to better handle the transmission of real-time data, including voice, we split TCP into two parts, one of which we called “Internet Protocol,” or IP for short. The two protocols combined were nicknamed TCP/IP.

TCP/IP was tested across the three types of networks developed by DARPA, and eventually was anointed as their new standard. In 1981, Jon Postel published a transition plan to migrate the 400 hosts of the ARPANET from the older NCP protocol to TCP/IP, including a deadline of January 1, 1983, after which point all hosts not switched would be cut off.”

In 1989, Sir Tim Berners-Lee was able to leverage the TCP/IP system to host a set of Interlinked hypertext documents which we know as the World Wide Web.
