Problem

What happens when a user searches for a website (e.g. www.cheetos.com)?

Asked in the systems round stage. This is a networking and systems fundamentals question. Reported follow-ups include HTTP(S) security and the TCP handshake.

Explain the request path from user input through name resolution, connection establishment, secure transport, HTTP request handling, response delivery, and browser rendering. Identify where caching, failures, retries, and latency occur. Discuss what changes for HTTPS and describe the TCP three-way handshake.
