Crc32 checksum algorithm

The original CRC checksum algorithm was invented by W. Wesley Peterson in 1961,the 32-bit CRC of Ethernet and many other standards is developed by several researchers and was published in 1975.

Crc32 checksum algorithm is a data checksum algorithm commonly used in networks and data storage to detect changes to data.

When data entering these systems , the data is attached with a short checksum value.

On the retrieval , the checksum calculation is repeated and if checksum values do not match. corrective action can be taken
