What protocol is primarily used for streaming video content?

The protocol primarily used for streaming video content is the User Datagram Protocol (UDP). This is because UDP is designed for applications where speed is more critical than reliability. In streaming video, data packets must be delivered quickly to provide a seamless viewing experience. If some packets are lost during transmission, the impact may be less detrimental than if the streaming were to be delayed while waiting for those packets to be re-sent, which is how protocols focused on reliability, like Transmission Control Protocol (TCP), operate.

UDP allows for faster delivery since it doesn't establish a connection or guarantee that packets arrive in order, making it suitable for real-time applications like streaming. With video content, real-time engagement and playback fluidity are prioritized; thus, any minor losses of data packets may be acceptable, allowing for continuous streaming without interruption.
