Explain that the lost acknowledgement does not necessarily enforce retransmission of the packet.
To guarantee reliable transfer, protocols utilize positive acknowledgement along with retransmission. Whenever receiver acquires the packet an acknowledgement is sent.
Generally packet is retransmitted, if an acknowledgement is lost. Retransmission cannot succeed if a hardware failure has lastingly disconnected the network or if getting computer has crashed. Hence, protocols retransmitting the messages bound the maximum number of transmissions. While the bound has been reached, the protocol stops retransmission of packet still if acknowledges is not acquired. Hence, lost acknowledgement does not necessarily enforce retransmission of packet.
