Cyclic Redundancy Check (CRC) is a method of error detection commonly used in digital networks and storage devices to detect accidental changes to raw data. The calculation involves treating the data as a large binary number and dividing it by a specific polynomial divisor. The remainder of this division becomes the CRC value, which is appended to the data. The receiving end performs the same calculation; if the calculated remainder matches the appended CRC value, the data is considered error-free.

Its significance lies in its ability to reliably detect common types of errors, such as those introduced by noise during transmission or storage corruption. Its relatively simple implementation makes it a computationally efficient choice for numerous applications, ranging from network protocols and data compression algorithms to file archives and hard drive verification. The concept has evolved over time, with various polynomial divisors being standardized for different applications, each designed to offer optimal error detection capabilities for specific data characteristics.
