Which protocol is known for its connectionless approach in real-time streaming applications where best effort delivery is sufficient?

The User Datagram Protocol (UDP) is recognized for its connectionless approach, making it particularly well-suited for real-time streaming applications where timely delivery is prioritized over reliability. In such scenarios, the ability to deliver data quickly is often more critical than ensuring that every packet is received and in the correct order. UDP achieves this by transmitting packets without establishing a connection, which reduces overhead and minimizes latency.

In applications like video streaming or online gaming, for instance, losing a few packets may not significantly disrupt the experience. Users often prefer that the application continues to deliver as much data as possible rather than waiting for packet retransmissions. UDP allows for this "best-effort" delivery, where the protocol does not guarantee that all packets will arrive at their destination or that they will arrive in the order they were sent. This trade-off makes UDP particularly useful in environments that demand real-time performance, acknowledging that some data loss may be acceptable in favor of lower latency and faster delivery.

Other protocols, such as TCP, emphasize reliability and data integrity, requiring a connection to be established before data transmission and ensuring that all packets are accounted for and in order, making it less suitable for real-time applications. Similarly, FTP and HTTP serve different purposes—FTP is focused on file
