PARITY MEMORY Meaning and
Definition
-
Parity memory, in the context of computer technology, refers to a type of memory that incorporates a form of error-checking called "parity checking." Parity checking is a method used to detect errors that may occur during the storage or transmission of data within a computer system.
In parity memory, each byte of data is accompanied by an additional parity bit. This parity bit is calculated based on the number of bits in the data byte that are set to 1. Parity can be of two types: even parity and odd parity. In even parity, the parity bit is set to ensure that the total number of 1s in the data byte, including the parity bit, remains even. Similarly, in odd parity, the parity bit is set to ensure that the total number of 1s, including the parity bit, remains odd.
During operation, the system constantly checks the parity of the incoming and outgoing data. If an error occurs during storage or transmission and the parity of the received data does not match the expected parity, the system can detect the error. Parity memory can then trigger an error notification or attempt error correction measures, depending on the capabilities of the system or application.
The use of parity memory can enhance the reliability of data storage and transmission in computer systems by detecting single-bit errors. However, it is important to note that parity checking is limited in its ability to detect and correct errors, particularly multiple-bit errors. Hence, other more advanced error detection and correction methods, such as ECC (Error Correction Code) memory, are often used in modern computer systems to provide higher levels of data integrity and reliability.

Etymology of PARITY MEMORY
The word "parity memory" does not have a specific etymology on its own as it is a combination of two terms: "parity" and "memory".
1. Parity: The term "parity" initially comes from the Latin word "paritas", which means equality or equivalence. It has been used in various contexts to describe the state of being equal or corresponding. In the field of computing, parity refers to a method of error-checking where an extra bit is added to a sequence of binary digits to ensure the total number of 1s (or 0s) is always odd or even. This helps in detecting errors during data transmission or storage.
2. Memory: The term "memory" originates from the Latin word "memoria" which means "faculty of remembering" or "memory". It has been used throughout history to describe the ability of a person or system to retain and recall information.
