        **What is Ordered Delivery?**

        Ordered delivery ensures that data packets arrive at the destination in the exact sequence they were sent, preserving the correct order of information.

        **How does Ordered Delivery work?**

        Protocols like TCP assign sequence numbers to packets and use acknowledgments to ensure packets are received and processed in the right order, buffering out-of-order packets if needed.
