User Datagram Protocol (UDP)
User Datagram Protocol (UDP) is a lightweight, connectionless transport protocol designed for fast data delivery on top of IP. Unlike TCP, UDP does not perform an initial handshake, assign tracking sequence numbers, require delivery acknowledgments, or execute retransmissions.
Because UDP avoids the overhead of connection setup and tracking states, devices can transmit data immediately. This "send and forget" approach offers minimal latency at the expense of guaranteed arrival or packet ordering.

Because UDP avoids connection setup and tracking states, it uses a "___ and forget" approach to achieve minimal latency.
Order the stages of a UDP data transmission process from initial data handling to completion.
Explain why UDP provides minimal latency and identify the trade-offs the engineer must accept regarding data delivery.
