Which RFC governs the User Datagram Protocol?

Explanation:
UDP is defined by RFC 768, which specifies its connectionless, best‑effort behavior and its lightweight header. UDP provides message boundaries and a simple 8‑byte header (source port, destination port, length, checksum) but offers no reliability, ordering, or flow control—relying on the application layer for any retransmission or sequencing if needed. This makes UDP fast and low overhead for time‑sensitive or simple queries. RFC 791 defines IP (the network layer), RFC 793 defines TCP (the reliable, connection‑oriented transport protocol), and RFC 792 defines ICMP (error reporting and diagnostics). Knowing these helps distinguish which RFC governs a given protocol.
