Cyclic Redundancy Checking (CRC) - Part 1

Error detection is an important part of communication systems when there is a chance of data getting corrupted. Whether it’s a piece of stored code or a data transmission, you can add a piece of redundant information to validate the data and protect it against corruption. Cyclic redundancy checking is a robust error-checking algorithm, which is commonly used to detect errors either in data transmission or data storage. In this multipart article we explain a few basic principles.
