Brief History of the Web
The World Wide Web was invented by Sir Tim Berners-Lee, a British computer scientist, in the late 1980s while working at CERN (European Organization for Nuclear Research) in Switzerland. Here's a brief overview of its evolution:
- 1989: Tim Berners-Lee proposed the concept of the World Wide Web while working at CERN. He developed the first web browser (WorldWideWeb) and web server;
- 1991: The first web page was created, consisting of text and hyperlinks. This marked the beginning of the web as we know it today;
- 1993: The web started gaining popularity outside of academic and research circles. The release of graphical web browsers like Mosaic and later Netscape Navigator made the web more accessible to the general public;
- Mid to late 1990s: The dot-com boom led to a rapid expansion of the web. Businesses began establishing an online presence, and e-commerce emerged as a significant aspect of the web;
- 2000s to present: The web continued to evolve with the introduction of dynamic web technologies such as CSS (Cascading Style Sheets), JavaScript, and server-side scripting languages. Social media platforms, cloud computing, and mobile devices have further transformed the web into an essential part of modern life.
Nowadays
HTML document is the foundation of a web page. Its main function is to organize content and establish a consistent format for presenting information on the Internet. Even the text you are currently reading and the images you are viewing are made possible by HTML.
When a user accesses a web page, their web browser sends a request to the web server hosting the page. The server then retrieves the HTML document associated with the requested URL and sends it back to the user's browser. The browser interprets the HTML code and renders the web page according to the specified structure, formatting, and content.
