Computer Networks interview questions

What happens when you open a website, TCP vs UDP, DNS and HTTP.

  1. What do the TCP flags SYN, ACK, FIN and RST mean?

    SYN starts a connection and syncs sequence numbers, ACK acknowledges received data, FIN politely closes one direction, and RST aborts the connection immediately. PSH asks the receiver to hand data to the app without waiting.
