The World Wide Web (web or “www”) is a network of data that can be accessed via the Internet. The documents are connected via different links. The World Wide Web is often called the Internet. However, these terms are not necessarily interchangeable. With the Internet, you can only access certain data in the World Wide Web. Similarly, there are many functions that the Internet offers, such as email, which have nothing to do with the World Wide Web.
In 1989, the European Organization for Nuclear Research in Geneva launched a project with hypertext systems. The goal of this project was to develop a system that allowed employees to easily exchange research data. At the start of this project, only text documents could be displayed. These text documents, and later pictures and graphics, were to be displayed with the help of a browser, what we know today as a web browser. In 1991, the World Wide Web was released for public use. This included 3 standards which provided the functionality of the web. The first is called HTTP, which is the protocol by which data is read from the network. The second standard is the HTML format, namely the programming language in which documents must be written in order to be visible in a browser. The final standard is the URL, which is the destination address of the requested documents. This serves to identify the desired Web page and allows for the precise usage of the Internet.
