UDP (User Datagram Protocol) is a transport layer protocol that is connectionless. Unlike TCP, UDP does not establish a dedicated end-to-end connection between two devices before transmitting data. Instead, it simply sends datagrams (packets) to the destination without verifying if they were received. This makes UDP faster and more efficient than TCP, but also less reliable. UDP is commonly used for applications that can tolerate data loss, such as online gaming, video streaming, and voice-over-IP (VoIP) services.
