Build the highway and watch the town grow.At first a few shops appear and maybe a restaurant.Then a hotel opens. Eventually new house are built. A village is born.
This is also how the virtual world has developed. Think of the Internet as the road carrying information between two computers.Think of the World Wide Web as the village. At first it is just a place on the virtual road where travelers meet. More travelers come bringing new kinds of information. New travelers come bringing new kinds of information.New villages are started.
Every willage has a founder.Tim Berners-Lee is the man who wrote the software programme that led to the foundation of the Word Wide Web.How did he get the idea? He tells us on his own web site. "One of the things computers were not able to do was store in formation from different sources. The dream behind the Web is of a common space in which we communicate by sharing information."
In 1991 his programmmes were placed on to the Internet.Everyone was welcome to use them.
Tim Berners-Lee could have followed the Microsoft route by forming a company to sell the programmes he invented. Or he could have joined another company. But in his view the Web is a language,not a pproduct. Charging a gee for using his programmes would have slowed the growth of the Web.And other companies would make similar products to compete. Instead of one World Wide Web there would be several smaller Webs. Each would use incompatible (不相容的) software. They Web is valuable because it uses a common computer language to reach people and share information. Competing webs would lose this value.Imagine if somebody sent you a bill every time you spoke a world of English.
In 1994 Tim Berners-Lee formed the World Wide Web Consortium,or W3C.More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone, no matter what their equipment or solftware,can work equally on the Web.
"The Web can help people to understand the way that others live and love. It helps us understand the humanity of people," he says.
