CRC16: Error Detection for Digital Data Transmission

CRC16 (Cyclic Redundancy Check 16-bit) is a type of error-detecting code used to detect errors in digital data transmission. It's a mathematical algorithm that generates a fixed-length checksum for a block of data. The checksum is sent along with the data and is recalculated at the receiving end. If the checksums don't match, an error has occurred in the transmission. CRC16 is commonly used in communication protocols such as Modbus, HDLC, and X.25.
