Focus on the sequence of events that occur from the moment you press Enter until the webpage is fully loaded. Start by discussing how the browser resolves the URL to an IP address using DNS (Domain Name System). Then, explain the process of establishing a TCP connection, including the role of the three-way handshake. Detail how the browser sends an HTTP request to the server, and how the server processes this request and sends back an HTTP response. Finally, touch on how the browser renders the page, including parsing HTML, CSS, and JavaScript. Be clear and concise, demonstrating your understanding of both networking and web technologies.
