It implements three-way handshakes, flow control, congestion algorithms, and full-duplex operation.\n\nUDP provides connectionless \"fire-and-forget\" transmission with best-effort delivery, no ordering guarantees, and minimal 8-byte headers (4% overhead). It uses stateless packet delivery with no connection phases, congestion control, or flow management.\n\nTCP powers applications demanding data integrity: web browsers, email clients, file transfers, databases, and messaging. UDP enables real-time applications where speed trumps reliability: online games, video conferencing, streaming services, VoIP, DNS, and IoT telemetry.\n\nChoose TCP when complete data integrity is essential, file transfers must be verified, or network conditions are unpredictable. Choose UDP for real-time requirements, when partial data loss is acceptable, or when implementing custom reliability layers.\n\nBoth protocols continue evolving through extensions like QUIC (HTTP/3), DTLS, and hybrid approaches that blend their characteristics for modern applications."}
