    cyclic redundancy check, what is it?

    I was recently downloading an item when I received the error,CYCLIC REDUNDANCY CHECK. Suddenly, the download stopped. What does that mean? Is it something that I should worry about? How can I fix it?

    Re: cyclic redundancy check, what is it?

    A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents; on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match. More information is given here - http://en.wikipedia.org/wiki/Cyclic_redundancy_check
