🔍📜 The "Crc" (Cyclic Redundancy Check) is an error-detecting code used in digital communication and storage systems. It involves performing mathematical calculations on a stream of data to generate a fixed-size checksum, which is then appended to the data. This checksum can be later recalculated and compared to detect any errors or modifications in the data. The Crc algorithm is widely employed in various protocols, such as Ethernet, Wi-Fi, and many others, ensuring data integrity and reliability in modern information systems.
