Topic notes
GATE CS tests TCP across three primary areas: congestion control dynamics (window growth phases, timeout recovery, and round-by-round segment tracking), sequence number wrap-around time and bit-budget calculations against MSL, and connection lifecycle mechanics (3-way handshake flags, state transitions during active/passive close, and crash recovery with RST segments). Questions are balanced between computational NATs involving RTTs and discrete bit math, and conceptual MSQ/MCQs focusing on byte-stream mechanics, piggybacking, and RFC 793 protocol invariants.

A connected UDP socket is a UDP socket on which connect function has already been called. Which of the following statements is/are CORRECT? I. A connected UDP socket can be used to communicate with multiple peers simultaneously. II. A process can successfully call connect function again for an already connected UDP socket.
