What does UDP stand for in networking protocols?

User Datagram Protocol
Uniform Data Protocol
Universal Datagram Protocol
User Datagram Procedure

The correct answer is: User Datagram Protocol

The correct answer is "User Datagram Protocol." This term refers to one of the fundamental transport layer protocols used in computer networking. UDP is designed for scenarios where speed is desirable and error correction is either not necessary or performed in the application layer. It emphasizes low-latency communication instead of reliable transmission, making it suitable for applications like video streaming, online gaming, and voice over IP (VoIP). The other options do not accurately reflect the correct terminology. "Uniform Data Protocol" and "Universal Datagram Protocol" are not recognized networking terms, and "User Datagram Procedure" incorrectly uses the term "Procedure" in place of "Protocol." Thus, "User Datagram Protocol" is the choice that correctly identifies the networking standard associated with this type of communication.
