Understanding Internet Architecture

This session introduces the fundamental processes that occur when a user accesses a website. We will cover: \- How a browser resolves domain names through DNS \- How IP addresses and routing deliver requests across networks \- How TCP/UDP enable reliable or real-time communication \- How HTTP/HTTPS requests retrieve web content \- How browsers render webpages from server responses The goal is to give students a clear, beginner-friendly understanding of the core mechanisms that make modern internet communication work.
