The CRC n-bits that are applied to each data block, work to ensure that the data that is sent, is the same data received, on the other end. The reasons why that is so important is because burst errors are the most common, as they occur in a number of difficult communication channels, such as optical and magnetic storage components. The main advantage of this error-correcting code is the fact that it’s much simpler to implement than other methods, and is also well suited for the detection of a number of different error types, particularly burst errors. This particular cyclic code was conceived by Wesley Peterson in 1961. In this post I’ll be talking about the data error cyclic redundancy check, what is it, why it was created, and what to do when you encounter one of these errors.Ĭyclic Redundancy Check or CRC is basically a method developed to ensure that data does not become corrupted during transmission.
