User Datagram Protocol (UDP)

User Datagram Protocol (UDP) is an alternative communications protocol to Transmission Control Protocol (TCP), used primarily for starting low-latency and loss-tolerating connections between applications and the internet. UDP is also known as a “stateless” protocol, meaning it doesn’t acknowledge that the packets being sent have been received. Due to UDP working this way, it is typically used for streaming services. You may hear some break up in the audio or see some skips in the video, but UDP transmissions prevents the stream from stopping completely.
