How is error detection and correction done? - Quora

· Briefly, error detection is determining whether the data was corrupted since it left the source; error correction goes beyond detection to determine exactly how the data was corrupted and restore it. Both error detection and error correction require some amount of redundant data to be sent with the actual data; correction requires more than detection.
