Final answer:
Online gaming is the typical use case for UDP among the given options, as it requires lower latency for real-time updates and can tolerate packet loss.
Step-by-step explanation:
Among the options provided, online gaming is a typical use case for the User Datagram Protocol (UDP) due to its loss tolerance and rate sensitivity. UDP is favored in gaming because it offers lower latency communication by sending packets without waiting for confirmation of receipt, which is ideal for fast-paced games where real-time updates are crucial.
By contrast, applications such as email servers, video conferencing, and database management systems typically require the reliability provided by TCP (Transmission Control Protocol) as they cannot afford to lose any data during transmission.
