In the development of the internet, who invented the World Wide Web (WWW) and created the first web browser and web server?

Introduction / Context:
The World Wide Web (WWW) is the system of websites and hyperlinks that most people casually call "the internet," even though the internet is actually the underlying network. This question tests your knowledge of who invented the World Wide Web and built the first web browser and web server. Understanding this inventor helps you appreciate how today's online world began as a research project at a European physics laboratory.

Given Data / Assumptions:

• The focus is on the World Wide Web, not the entire internet.
• The question asks specifically about the inventor of the WWW.
• It also implies creation of the first browser and web server software.
• We assume a time frame around the late 1980s and early 1990s.

Concept / Approach:
The internet existed before the World Wide Web as a collection of interconnected networks. The World Wide Web, invented at CERN, added the concepts of web pages written in HTML, linked through URLs, and accessed with browsers using HTTP. The scientist who proposed this system and implemented the first browser and server is Sir Tim Berners-Lee. To solve the question, recall that his work at CERN around 1989–1991 gave birth to the web as we know it, a crucial distinction from other inventors listed in the options.

Step-by-Step Solution:

Verification / Alternative check:
To verify, think of how often textbooks and articles mention "Sir Tim Berners-Lee, inventor of the World Wide Web." He is consistently credited with writing the proposal and implementing the first working system at CERN. The other individuals in the options are known for very different inventions, such as adhesive bandages or ballpoint pens, which confirms that they are not associated with the WWW. This cross-check makes it clear that Sir Tim Berners-Lee is the only correct choice.

Why Other Options Are Wrong:
Earle Dickson invented the Band-Aid adhesive bandage, not an internet technology. James Rinehart is not historically known as the inventor of the web. László Bíró invented the modern ballpoint pen, which transformed writing tools but has nothing to do with computer networks or web browsers. None of these options relate to the creation of the World Wide Web system.

Common Pitfalls:
Some learners confuse the inventor of the World Wide Web with the creators of the underlying network technologies, or they assume that some large company created the web. Another mistake is to mix up Tim Berners-Lee with other computer pioneers. Always remember that his contribution is specifically the standardized combination of URLs, HTTP, and HTMLpages that we now call the World Wide Web, separate from the invention of computers or the internet itself.

Final Answer:
The World Wide Web (WWW) was invented by Sir Tim Berners-Lee.
