The Internet is the biggest source of information in the world,and it's accessible through a computer.It consists of millions of pages of data.
In 1969,DARPA,a U.S.defence organisation,developed a way for all their computers to "talk" to each other through the telephone.They created a network of computers called DARPANET.For fifteen years,only the U.S.army could use this system of communication.Then in 1984,the U.S.National Science Foundation (NSF) started the NSFNET network.It then became possible for universities to use the system as well.NSFNET became known as the Inter-Network,or "Internet".
The World Wide Web (the web) is a computer network that allows computer users to access information from millions of websites via the Internet.At the moment,about 80 percent of web traffic is in English,but this percentage is going down.By 2020,much web traffic could be in Chinese.
The World Wide Web was invented in 1991 by an English scientist,Tim Berners-Lee.Berners-Lee built his first computer while he was at university using an old television!He came up with the idea of the World Wide Web in 1989 while he was working in Switzerland.
Berners-Lee made it possible for everyone to use the Internet,not just universities and the army.He designed the first "web browser",which allowed computer users to access documents from other computers.From that moment on,the web and the Internet grew.Within five years,the number of Internet users rose from 600 000 to 40 million.
The Internet has created thousands of millionaires,but Berners-Lee is not one of them.Everyone in the world can access the Internet using his World Wide Web system.He now works as a lecturer at Massachusetts Institute of Technology in Boston.
