Unveiling the Birth of the Internet: From DARPA to the World Wide Web

In the second part of the episode, the history of the internet is explored, starting with the launch of the Sputnik satellite by Russia in 1957.

The United States reacted to the launch of Sputnik by establishing the Defense Advanced Research Projects Agency (DARPA) to compete technologically with Russia.

DARPA sponsored universities to conduct advanced computer science research and proposed the creation of the ARPANET, which was a precursor to the internet.

💡 The development of packet switching allowed for a distributed network that could send data in packets through various routes.

🌐 The ARPANET, the first node of the internet, was established in 1969, followed by the implementation of the 1822 Network protocol in 1970.

💻 Packet switch networks started to gain popularity, leading to the creation of individual networks with their own protocols.

📡 In the 1970s, the government noticed the potential of computers in command and control, leading to the development of satellite-based packet switch networks called satnet.

🌐 To solve the problem of connecting different packet switch networks, a protocol called TCP/IP was invented, allowing networks to communicate and share data.

💻 In 1983, all 400 computers on the government-funded arpanet were required to switch to TCP/IP, paving the way for the modern internet.

🌐 The video discusses the development of TCP/IP and the split between TCP and IP.

💻 TCP and IP are used for data transmission, but UDP is used for faster transmission in certain scenarios.

🌐 The internet was officially turned on on January 1st, 1983, and has been running ever since.

📚 The DNS system was created as an improvement to the IP address indexing problem.

🔗 Vint joined the private sector and developed MCI Mail, an early version of commercial email.

🌐 The internet was initially developed for military research, but Vint Cerf and Bob Kahn started exploring its potential for commercial use by creating digital libraries and AI prototypes.

🔧 As the internet grew, the National Science Foundation and other government organizations wanted to connect more universities, leading to the emergence of internet backbones and the need for networking equipment manufacturers.

💡 Vint Cerf realized the importance of giving the general public access to the internet, leading to the idea of commercializing it and connecting email services like MCI mail to the internet.

🌍 This decision opened up the floodgates for other businesses to connect to the internet, leading to the development of internet service providers and the eventual creation of the World Wide Web by Tim Berners-Lee in 1989.

🔍 The World Wide Web revolutionized the way people consume information on the internet by introducing hypertext and search engines.

🌐 Hypertext was originally useful for jumping around a single document, but connecting it to the internet allowed for faster information discovery.

📡 The browser Wars started in 1999, with Tim Berners-Lee creating the World Wide Web and the first internet browser.

🪐 The idea of an interplanetary internet emerged, with the need for an interplanetary backbone network and new protocols to handle the long delays and distance between planets.

⚾️ The secret history of the internet involves transmitting data through space with satellites and the inverse square law.

🛰️ A new interplanetary internet system is being developed using storage forward networking and protocols that allow faster data transfer.

🔭 Commercial interest in space exploration is increasing, leading to the possibility of an interplanetary backbone network.
