In everyday language, the Internet and the worldwide web (www) are often interchangeable concepts, but there are clear differences between the two. Born from a predecessor from 1969, the Internet as we know it started in 1983. The basis of the internet is TCP/IP, a standard for communication between computers. The existence of the internet enabled the creation of the worldwide web (www or simply 'the web').
The web started in 1991 and was invented by Tim Berners-Lee, now director of the W3C. The web cannot exist without the internet; it’s one of the applications that run on the internet (email is an example of another application). The web itself is also based on standards. The most important are HTTP - a protocol for the exchange of hypertext (text with hyperlinks, like this blog), HTML - a standard format for the layout of hypertext, and the URL or URI - a universal resource identifier.
The creation of the web made it possible to publish and link text documents in a universal way. In addition to text, (silent or moving) images were later shared via web standards as well, and nowadays, web browsers can do so much that they can be regarded as fully-fledged operating systems (such as Windows or Linux). That the web has had a huge impact on the world is almost an understatement. Worldwide communication has changed drastically and the web has also prompted radical social, economic, cultural, and political change. The web itself, however, is also changing. There is a growing tendency to use the web for sharing raw data, which is a source of information and knowledge. It forms the foundation of many decisions made by companies, authorities, and citizens.
