In this beginner-friendly session, we’ll break down how the internet really works behind every web app. You’ll learn what happens when you click “Login,” how HTTP requests and responses flow across the network, and how cookies and sessions help websites remember you. We’ll visualize these steps using browser examples, packet flow diagrams, and practical explanations that connect networking to real-world web security topics like authentication and data protection. Perfect for anyone new to networking or cybersecurity.
