Recent improvements in hardware and software design reduce parity problems as well. BackgroundWhat is a processor or memory parity error?Parity checking is the storage of an extra binary digit (bit) in order to represent the parity (odd or even) of a small amount of computer data (typically one byte) while that data is stored in memory. The parity value calculated from the stored data is then compared to the final parity value. If these two values differ, this indicates a data error, and at least one bit must have been changed due to data corruption.Within a computer system, electrical or magnetic interference from internal or external causes can cause a single bit of memory to spontaneously flip to the opposite state. This event makes the original data bits invalid and is known

The errors that cause crashes are typically detected by processor hardware, which automatically branches to special error handling code in the ROM monitor. The ROM monitor identifies the error, prints a message, saves information about the failure, and restarts the system. Prerequisites Requirements There are no specific requirements for this document.
