Which protocol typically has lower latency due to less overhead?

The correct choice is related to the nature of the User Datagram Protocol (UDP), which is designed for scenarios where speed and efficiency are prioritized over reliability. Unlike Transmission Control Protocol (TCP), which establishes a connection and requires acknowledgment of each packet sent, UDP sends packets without waiting for an acknowledgment. This results in reduced overhead and typically leads to lower latency.

UDP is frequently used in applications where low latency is crucial, such as video streaming, voice over IP (VoIP), and online gaming, where the speed of data transmission is more critical than guaranteed delivery of each packet. The lightweight nature of UDP allows it to be faster compared to protocols that have more overhead due to connection establishment and error checking processes.
