A(n) is a calculation (using encryption technologies) based on the contents of a disk or file. they are engineered so that even small changes in the source data will produce significantly different checksum results. cyclic random check number cyclic redundancy check number cyclic repetition check number random variable check number

Cyclic redundancy check number

Explanation:

Cyclic redundancy check number (CRC) is the process through which the accidental errors are detected through the codes in a particular communication path and digital networks. They can identify the small defects or errors occurring in data by observing checksum result ,so can be detected while transmission.

Other options are incorrect because random variable check number detects the error of occurring in sequence of random variable.Cyclic repetition check number is checking of defects in numbers through reoccurring method.Cyclic random check number is continuously checking the error in random numbers  

dont understand question can you makeit more better

i am a priest who cares deeply about the church. i have been called here to explain my views on indulgences and other proposed reforms. i would like to explain why my views are consistent with the bible and are correct.
