Retransmission
Retransmission refers to the process of sending a message, signal, or data packet again after it has been received, usually due to errors in transmission or loss of information. This can occur in various communication systems, such as telecommunications, computer networks, and broadcasting, to ensure the successful delivery of information from sender to receiver. Retransmission helps to improve the reliability and accuracy of data transmission by allowing for the re-sending of data that may have been corrupted or lost during the initial transmission.
