What is CRC and what impact over Network or data flow

Question

Accepted Answer

CRC stands for Cyclic Redundancy Check. It is an error-detecting code used in network communication to ensure data integrity.

CRC is a mathematical algorithm that generates a fixed-size checksum for a block of data.
The checksum is appended to the data and is recalculated at the receiving end to check for errors.
If the calculated checksum doesn't match the received checksum, it indicates that the data has been corrupted during transmission.
CRC helps in detecting errors caused by noise, interference, or faulty hardware.
It is commonly used in Ethernet, Wi-Fi, and other network protocols to ensure reliable data transmission.

Accepted Answer

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents
