UDP stands for User Datagram Protocol, which is a core protocol of the Internet Protocol Suite used for sending messages, called datagrams, across a network. One of the key features of UDP is that it is a connectionless protocol, meaning it does not establish a connection before sending data and does not guarantee the delivery of packets. This makes it suitable for applications where timely delivery is more critical than reliability, such as video streaming, online gaming, and voice over IP (VoIP).

In contrast to other protocols like TCP (Transmission Control Protocol), which provides error checking and guarantees delivery, UDP operates with lower overhead and enables faster data transmission. This classifies it as a lightweight protocol, catering to applications that can tolerate some data loss but require low latency. Thus, the term "User Datagram Protocol" accurately reflects its design intended for user-level applications sending discrete messages in an efficient manner.
