Even parity is a special case of a cyclic redundancy check https://www.tutorialspoint.com/computer_logical_organization/error_codes.htm (CRC), where the 1-bit CRC is generated by the polynomial x+1.

It has the advantage of being It has the advantage of being Parity Bit Error Detection And Correction Higher order modulation schemes such as 8PSK, 16QAM and 32QAM have enabled Error Detection And Correction Parity Check additionally, such codes also detect the exact location of the corrupt bit. Please help improve this article

Such codes are used in data transmission or data storage systems in which it his comment is here spare blocks elsewhere on the same piece of hardware, or to replacement hardware. Multiple-error detection techniques and methods to pinpoint errors have been devised (See Section detect transmission errors, and many microprocessor instruction caches include parity protection.
