Why network might used an error correcting code instead of error detection?

Networks might use error-correcting codes instead of error detection to ensure data integrity and reliability, especially in environments where retransmitting data is costly or impractical, such as in real-time communications. Error-correcting codes allow the receiver to identify and correct errors without needing a retransmission, thus enhancing throughput and reducing latency. This capability is particularly valuable in applications like satellite communications or streaming media, where maintaining a continuous flow of data is crucial.
