What Happens When You Type a URL?

Most people think websites open instantly. Reality? 💀

The moment you type a URL in your browser, an insane engineering chain reaction starts behind the scenes:

✔️ DNS lookup
✔️ IP address resolution
✔️ TCP Handshake
✔️ Server communication
✔️ Database queries
✔️ HTML, CSS & JavaScript rendering

…and all of this happens in milliseconds! ⚡

Your browser first asks: “Where does Google.com live?” 🌍
DNS works like the internet’s contact book and returns the server’s IP address. Then your browser connects to that server, requests data, receives code, and finally renders the website you see on screen.

This is the core foundation of Web Development, Computer Networks, Backend Engineering, System Design, and Internet Architecture.
