Internet Basic Concepts

Internet Basic Concepts is a beginner-friendly course designed to give students a clear and practical understanding of how the internet works behind the scenes. Whether you’re just starting your digital journey or aiming to strengthen your foundational knowledge for more advanced tech topics, this course demystifies the core concepts that power everything online.

You’ll start by exploring what the internet really is—its history, structure, and how billions of devices are connected worldwide. From there, you’ll learn how the internet works in simple terms, including how data travels from one point to another through servers and networks.

We’ll break down the differences between HTTP and HTTPS, why secure connections matter, and how they affect your online privacy. Then, you’ll dive into the meaning of domain names and hosting, including how websites are stored and made available globally. Finally, you’ll discover what DNS is—the “phonebook of the internet”—and understand how it helps translate domain names into actual web addresses.

Each chapter is explained in plain language with real-world examples, diagrams, and interactive exercises to help you build confidence in your understanding of internet technologies.
