A Cyclic Redundancy Check is done as a first attempt to prevent corrupted data.

A cyclic redundancy check error or CRC error occurs when the data verification value is a redundancy. This is used in detecting common errors caused by noise in transmission channels.

A cyclic redundancy check is a piece of computer code used to ensure that raw code has not been updated. Further information can be found on the cyclic redundancy check Wikipedia page.
