Foundations of the Internet and the World Wide Web

Every click, search, and cloud service relies on a massive global network, yet few professionals understand how these systems actually communicate. This text-based course demystifies the foundational technologies that make the digital world function, clearing up the common confusion between the physical network and the information layer built on top of it. You will transition from a passive user to a tech-literate professional who understands routing, addressing, and web delivery, building a rock-solid mental model of network layers and modern web architecture. What you'll learn: Understand the critical differences between the physical Internet infrastructure and the World Wide Web; Explore how data travels across the globe using IP addressing, DNS, and routing protocols; Master the fundamentals of web communication, including HTTP/HTTPS, client-server models, and modern TLS encryption; Explain the role of modern content delivery networks (CDNs) and edge computing in speeding up web access; Analyze how IPv6 and modern web standards are shaping the future of global connectivity. You will start by learning essential terminology and historical context before diving into IP routing, DNS resolution, and web protocols. The course guides you step-by-step through the journey of a single web request from your browser to a cloud server and back. This course is designed for absolute beginners, aspiring cloud engineers, and web developers looking for a clear, conceptual introduction to network fundamentals with no prior coding or IT experience required.
