As most of the modern communication is digital in nature i.e., sequence of 1’s and 0’s, there is a chance that a 1 is replaced by 0 and a 0 is replaced by 1.Ĭyclic Redundancy Check or CRC helps in detecting the errors in sequence of bits. It is a technique used in computer networks to detect and correct errors in digital data. CRC is short for Cyclic Redundancy Check.
