Error Detecting Codes ( Implemented either at Data link layer or Transport. Unlike checksum scheme, which is based on addition, CRC is based on binary division. If at this step there is no remainder, the data unit is assumed to be correct. While the CRC is excellent for error detection, on its own this makes it unreliable as a means of error. ERROR CORRECTION USING THE CRC 55. 4 Error detection 97 2. 3 Cyclic Redundancy Check It should be clear by now that a major goal in designing error.
