Definition
UDP is a lightweight transport protocol that sends datagrams without guaranteeing delivery or order, trading reliability for lower latency.
Real-World Example
Online games and some video calls prefer UDP so a lost packet is skipped rather than delaying the whole stream waiting for retransmission.
