However, there are well known methods to reduce the complexity of the calculations so that the effort is not much greater than using a checksum and the performance is much better. This means that they are more complicated to implement and more time is required to calculate them. The disadvantage of using CRCs instead of checksums is that they use more complicated algorithms. Using CRCs, a higher number of bit errors and different error patterns can be detected. Polynomial division is used to calculate CRCs and they are much more robust than checksums. Using a checksum, it may not be possible to detect errors if bits are switched or there are multiple errors that cancel each other out. Data is split in to chunks of bits and added together to calculate a check sequence. If the results are the same it is very likely that the data has been transmitted correctly.Ī checksum is calculated using an additive process. The two results are compared to check if the data has become corrupted. A calculation is performed on the data when it is transmitted or stored and again when it is received or read. ![]() Checksums and Cyclic Redundancy Checks (CRC) are both methods of error detection, used when transmitting or storing data.
