Description
Understanding URLs & Domains for Beginners is a practical, easy-to-follow course designed to help you understand exactly how web addresses really work. If you’ve ever wondered what all the parts of a URL mean, how domain names function, or what happens behind the scenes when you type a website address into your browser, this course is perfect for you.

You’ll start by learning what URLs are and why they matter, using everyday examples from search engines, social media, and online shopping sites. From there, you’ll break down the anatomy of a URL, including protocols, domains, subdomains, paths, queries, and fragments, while also learning to avoid common beginner mistakes.

The course then introduces domain names and explains how human-friendly names relate to IP addresses, along with an overview of top-level domains and how domain registration works. You’ll also explore the Domain Name System (DNS) to understand how websites are located, why some domains fail to load, and what happens when a domain can’t be reached.

Security is a key focus, helping you recognize trustworthy URLs, spot fake or misleading web addresses, and develop safe browsing habits. Finally, you’ll apply your knowledge through hands-on URL analysis and a mini project, before wrapping up with a review of essential terms and actionable next steps.
