Final answer:
The World Wide Web's architecture is largely derived from Tim Berners-Lee's original development while at CERN, where he created HTML, URI, and the first web server. His contributions were pivotal in forming what we know as the internet today.
Step-by-step explanation:
The architecture of the World Wide Web is largely based on Tim Berners-Lee's original creation. While working at CERN in Switzerland, Tim Berners-Lee proposed "Information Management: A Proposal" in 1989, laying the foundations for the web. By 1990, he had created three crucial technologies: HTML (Hypertext Markup Language), URI (Uniform Resource Identifier), and the first web server on his NeXT computer at CERN. Berners-Lee's vision was materialized in the form of a vast, interconnected information system that was made freely available to the public after collaboration with other researchers like Ted Nelson who conceptualized hypertext. It was the development of the MOSAIC browser by Marc Andreessen in 1993 that widely disseminated these technologies, laying the cornerstone for today's internet architecture.
