SCSI PARITY Meaning and
Definition
-
SCSI parity refers to a method used in computer systems to detect and correct errors in data transmission through a Small Computer System Interface (SCSI) bus. It is a form of error checking mechanism that helps ensure the integrity and accuracy of data being transferred between SCSI devices.
When data is transferred over a SCSI bus, it is susceptible to various issues such as electrical noise, crosstalk, or signal degradation, which can result in the transmission of incorrect data. SCSI parity aims to detect and rectify such errors.
Parity bits are added to the transmitted data during the SCSI transfer process. These bits represent the number of 1s in each byte of data being sent. The parity bit is then appended to the byte, making the total number of 1s either even or odd.
During the receiving process, the SCSI controller checks the received byte along with its associated parity bit. If the total number of 1s in the byte, including the appended parity bit, does not match the expected parity value (even or odd), then an error is detected, indicating that an error occurred during transmission.
If an error is detected through the parity check, the SCSI controller can request the data to be resent, ensuring the accuracy of the information being transmitted.
SCSI parity is an essential component of SCSI data transmission, as it adds a layer of reliability to data transfers, minimizing the chances of corrupted or incorrect data being initiated or received by SCSI devices.

Etymology of SCSI PARITY
The term "SCSI parity" is derived from two different sources:
1. SCSI: SCSI stands for Small Computer System Interface, which is a set of standards for physically connecting and transferring data between computers and peripheral devices such as hard drives, scanners, printers, etc. The term SCSI originated as an acronym for "SASI" (Shugart Associates System Interface), named after the company that developed the initial standard. Over time, it evolved into "SCSI" to reflect the various improvements and expansions made to the original specification.
2. Parity: In computer systems, parity refers to an error-checking technique used to detect errors in data transmission. It involves adding an extra bit (parity bit) to a binary code to ensure that the total number of 1s in the code (including the parity bit) is either even (even parity) or odd (odd parity).
