Join Doug Winnie for an in-depth discussion in this video How the Internet was born, part of Computer Science Principles: The Internet.
- The internet can be traced back to the 1960s,…when transmission of digital information…started out in its infancy.…What we call the internet,…first started as a project for the United States government.…A network called the ARPANET,…or Advanced Research Projects Agency Network…was established in 1969,…as a communication network for the Department of Defense.…In order for the network to work,…it needed to have a way for information to be sent reliably,…from one point of the network to another.…
These blocks of information…that are sent are called packets,…and they need to be transmitted multiple times,…simultaneously.…To do this, a set of rules needed to be created.…In the 1970s, Vint Cerf and Robert Kahn…created two sets of rules to do exactly that,…the Transmission Control Protocol and the Internet Protocol,…or TCP/IP.…In 1982, TCP/IP was introduced…as the standard networking protocols on the ARPANET,…which remained under the control of the government…through most of the 1980s.…
In 1990, Tim Berners-Lee created an application called…
This course is the second in our Computer Science Principles series, designed around the AP Computer Science Principles (CSP) curriculum. It is a great foundation for anyone, at any age, to prepare for careers in technology and computer science. Understanding basics like the Internet will help you understand the interplay between hardware, software, data, networks, and the people that use them.
