A Cyclical Redundancy Check (CRC) is a method used in computing to ensure the accuracy of data as it is being transferred from one location to another. It is a type of error-detecting code that is used to detect accidental changes that may occur in raw data. Here are the steps to understand how it works:

1. CRC begins with a set of binary digits that need to be transmitted, which is appended by a sequence of derived CRC bits.

2. Both the data and the CRC sequence are sent to the receiver.

3. Upon receiving the data, the receiver generates a new CRC based on the received data and compares it to the received CRC.

4. If the generated CRC matches the received CRC, then the data is considered valid. If not, the data is considered corrupted and the receiver can request a retransmission.

This process helps to ensure the integrity of data as it is being transferred, making it a crucial part of data communication.
