Ever wonder what actually happens between clicking a link and a page appearing on your screen? This talk breaks it down — no jargon, no assumptions. We'll walk through the real infrastructure behind everything you do online:🌍 What the internet actually is (and isn't — it's not "the cloud")
🔌 The physical stuff
🏠 IP addresses
📖 DNS
📦 How your data travels in packets across the world
📚 The TCP/IP stack
🌐 HTTP & HTTPS
🔄 The full life of a web request, from click to loaded pageThis is useful for anyone who interacts with the tech industry, even in a non-technical role. Understanding what's happening under the hood helps you have better conversations with engineers, ask smarter questions, and understand what is and isn't possible.
No laptop required. This is a talk, not a workshop. Just bring your curiosity.
We will also live stream the event (https://youtube.com/live/5qW4aQW7D8Y).
Food will not be provided, but we encourage people to grab food together after the event.
This event and all Code Seoul events are FREE. We are a non-profit organization dedicated to providing tech education to the Seoul community.
