Every layer of the stack you understand today is one less mystery in production tomorrow.
A BSc student asks Sumantrak
“explain what happens when you enter a URL in a browser”
The browser resolves the domain into an IP address via DNS, opens a TCP connection to the server, sends an HTTP request, and renders the HTML/CSS/JS it gets back. Viva tip: examiners often push further — ask about HTTPS's TLS handshake or how DNS caching speeds up repeat visits, so have one layer of follow-up ready.
