summary
Dives into what actually happens: UDP DNS lookup then TCP three‑way handshake then SSL handshake then HTTP request, demonstrated end to end with net internals, nslookup and traceroute and packet captures in Wireshark. Shows TCP SYN/ACK exchanges, HTTP over reused connections, and measures a DNS round about 100 ms DNS delay (≈113 ms). Builds an EEG‑controlled Chrome Dino and demos raw HTTP with putty/netcat so the tools and timings, not the topic, decide whether to watch.
