What Actually Happens Between Typing a URL and a Webpage Loading

When a user types a URL and presses Enter, the browser first parses the address into its components — protocol, domain, and path — before initiating any network activity. It then checks multiple cache layers to determine whether stored data can be reused, potentially speeding up the process. If a network request is needed, DNS translates the human-readable domain name into a numeric IP address so the browser knows where to connect. For secure HTTPS connections, a TLS handshake is performed to establish encryption, authentication, and data integrity before any content is exchanged. Finally, the server responds with HTML, CSS, and JavaScript resources, which the browser processes and renders into the visible webpage.
