Can you make a diagram of the sequence of protocol events involved in requesting a web page using a URL?

Certainly! When you request a web page via a URL, the sequence of protocol events typically follows these steps: First, the browser resolves the URL to an IP address using DNS (Domain Name System). Next, it establishes a TCP connection to the server using the IP address. The browser then sends an HTTP request to the server for the web page. Finally, the server processes the request and sends back the HTML content, which the browser renders for display.
