RFC 768 (Request for Comments 768)

RFC 768 defines the User Datagram Protocol (UDP), a fundamental communication protocol used in networking. UDP allows computers to send messages, called datagrams, quickly and with minimal overhead, making it suitable for real-time applications like streaming or online gaming. Unlike other protocols that ensure every message arrives correctly, UDP sacrifices some reliability for faster transmission. It operates independently of connection setup, enabling rapid data exchange. Overall, RFC 768 sets the standard for how these fast, lightweight messages are formatted and transmitted across networks.
