What Does Parity Error Mean?

A parity error is an error that results from irregular changes to data, as it is recorded when it is entered in memory. Different types of parity errors can require the retransmission of data or cause serious system errors, such as system crashes.

Techopedia Explains Parity Error

The source of a parity error is a parity bit or check bit. This bit is added to a byte or other piece of code to show whether the number of bits included is even or odd. If this parity bit is checked later and found to be inaccurate, it can trigger a parity error.
