When the Soviet Union launched Sputnik, beating American in some of the early first steps of the space race, American created an agency known as the Advanced Research Projects Agency (ARPA). They hoped to demonstrate their techonolgical skill to both the Soviets and the rest of the world. One of the early projcets of ARPA was the ARPANET. ARPANET was the worlds first packet switching network.
There were four computers on ARPANET. One each at UCLA, Stanford, UC Santa Barbara, and the University of Utah. At 10:30 PM on October 29, 1969, a message was sent from the computer at UCLA to the one at Stanford. The message was supposed to be the word "login." The "l" and the "o" transmitted without problem but then the system crashed. Hence, the first message on the ARPANET was "lo".
PCs were first made available to consumers in the late 1970. By the mid 1980s, and early 90s, many households had one. Once the World Wide Web was invented in the early 90s, the hardware was already in place for people to use the internet.
But growth didn’t happen overnight. In fact, growth was incredibly slow. In 1970 the number of computers on this new network had grown from 4 to 13. In 1971 the number would increase to 23. It wouldn’t be until 1977 before the hundred computer barrier would be broken, and not until 1984 before more than a thousand computers were on the network.
The internet is the framework and protocols used to connect computers together. In the beginning the internet resided largely on phone lines. In recent years, the internet has moved to fiber networks (cable), and wireless networks. What the internet sits on doesn't matter as much as the protocol computers use to talk to each other.
he World Wide Web was created by Sir Tim Berners-Lee during a year long period from 1989 to 1990. The web is an application built on top of the internet. When most people say they are using the internet, they mean they are using the World Wide Web. A person accesses the web by using a browser. The browser displays documents on the web.
