Explanation:
Detailed explanation-1: -How to Detect and Correct Errors? To detect and correct the errors, additional bits are added to the data bits at the time of transmission. The additional bits are called parity bits. They allow detection or correction of the errors.
Detailed explanation-2: -Retransmission : The heart of the error control mechanism is the retransmission of segments. When a segment is corrupted, lost, or delayed, it is retransmitted. In modern implementations, a segment is retransmitted on two occasions: when a retransmission timer expires or when the sender receives three duplicate ACKs.
