Show understanding of the differences between the World Wide Web (WWW) and the internet

2.1 Networks – The Internet and the World Wide Web

What is the Internet?

The Internet is a global network of interconnected computers and devices that communicate using standard protocols (TCP/IP). Think of it as a huge road system that carries data packets between cities (computers) all over the world. 🚗💨

What is the World Wide Web?

The World Wide Web (WWW) is a service that runs on the Internet. It uses the HTTP/HTTPS protocol to retrieve and display web pages (HTML documents). Imagine the Web as a library where each book is a web page, and you use a browser to read them. 📚🖥️

Key Differences

How They Work Together

1. Data travels across the Internet using routers and switches.
2. When you request a web page, your browser sends an HTTP request over the Internet.
3. The server responds with the page’s HTML, CSS, and images.
4. Your browser renders the page, and you see the content.
