Topic notes
In GATE CS, the 'DNS and HTTP' topic is tested predominantly through conceptual protocol interaction, chronological packet sequencing, connection lifecycle mechanics, and timing calculations. Early exams focused on basic protocol roles (SMTP, POP3, HTTP), statefulness, and HTML/XML properties, whereas recent exams (2020–2026) strongly emphasize quantitative analysis of iterative DNS hierarchies, persistent vs. non-persistent HTTP, pipelining, and total round-trip time (RTT) latency.
