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.
