        **What is Reliable Data Transfer?**

        Reliable data transfer ensures that data is delivered accurately, completely, and in the correct order from sender to receiver. It typically involves error detection, acknowledgment, and retransmission mechanisms.

        **How does Reliable Data Transfer work?**

        Reliable transfer mechanisms use acknowledgments (ACKs), sequence numbers, timeouts, and retransmissions to ensure that lost or corrupted packets are resent and correctly ordered at the receiver's end.
