Explanation:
Detailed explanation-1: -Error detection allows the receiver to determine if there has been a transmission error. It cannot rebuild the correct data and must either request a retransmission or discard the data. With error correction, the receiver detects an error and tries to correct as many error bits as possible.
Detailed explanation-2: -Forward error correction (FEC) is an error correction technique to detect and correct a limited number of errors in transmitted data without the need for retransmission. In this method, the sender sends a redundant error-correcting code along with the data frame.
