______________ is a connection-less protocol that does not assume reliability from lower layers, which does not provide reliability, flow control, or error recovery.

Understand the Problem

The question is asking to identify a protocol that does not provide reliability, flow control, or error recovery, focusing on the characteristics of connection-less protocols.

More Information

The User Datagram Protocol (UDP) is a connectionless protocol that provides no guarantees for message delivery, ordering, or error correction. This makes it faster and suitable for applications like video streaming where speed is critical.

Tips

A common mistake is confusing UDP with TCP because they both operate on the transport layer. Remember, TCP is reliable and connection-oriented, while UDP is not.
