Have you ever wondered what happens when you type abc.com and press Enter? Your page seems to arrive in one move, but your browser takes several steps first. It checks for a saved address. If it has one, it uses it. Otherwise, DNS-the internet's phonebook-finds the site's numerical IP address. But finding the server isn't getting the page. It only tells your browser where to ask. Your computer opens a connection, then secures it with TLS, which encrypts information traveling between them. Only then does your browser request the page. The server replies with files: HTML provides structure, CSS appearance, and JavaScript behavior. Your browser combines them and renders the page you see. So after you press Enter, your browser finds the server, connects securely, asks for the page, and turns the returned files into the website on your screen.
