What happens to the HTTP request after DNS resolves the domain?

• A. TCP splits the request into packets
• B. HTML is rendered
• C. DNS resolves again
• D. The user signs in

Answer: (A)

After DNS resolves the domain, the browser uses the server’s IP to open a TCP connection and send the HTTP request. TCP handles reliable transport by breaking the request into smaller pieces called segments, which travel as IP packets across the network. The server then reassembles those packets into the full HTTP request and processes it. Rendering HTML happens after the server responds with data, not during the request phase. DNS would not typically resolve again for the same request, and signing in is an action that occurs after the page is loaded or during interaction, not during the basic sending of the request.
