UDP
User Datagram Protocol ”” a connectionless transport protocol that prioritizes speed over reliability.
Also: User Datagram Protocol
Definition
UDP (User Datagram Protocol) is a connectionless transport protocol that sends datagrams without establishing a connection or guaranteeing delivery, ordering, or error correction. Unlike TCP, UDP does not retransmit lost packets or wait for acknowledgments, making it faster and more suitable for real-time applications where low latency is more important than perfect reliability. UDP is used for video streaming, online gaming, voice over IP (VoIP), DNS queries, and live broadcasts.
Example
“Video calls use UDP so that a few lost audio packets cause a brief glitch rather than causing all subsequent audio to be delayed waiting for retransmission.”
Usage Examples
- 1
“The team applied udp best practices to improve their networking outcomes significantly.”
- 2
“Understanding udp is essential for anyone building a career in IT & Technology.”
