A binary 1 is moved and a binary 0 is getting or a binary 0 is moved and a binary 1 is getting. Cyclic Redundancy Check is the most important method to detect the errors occurred during transmission of any data. Errors transpired in communication due to internal and external factors i.e. due to components, link, design, noise and interference etc. This work is focused on study of encoder and decoder of CRC
