The process of detecting and correcting errors that occur during data transmission or storage.	Bits added to binary data to ensure an even or odd count of 1s.
A method of error detection where the number of 1s, including the parity bit, is always even.	A method of error detection where the number of 1s, including the parity bit, is always odd.
The inclusion of extra information or resources in a system to improve reliability and provide backup in case of failures.	The process of detecting and correcting errors that occur during data transmission or storage using error correction codes.
The assurance that data remains accurate, consistent, and complete throughout its lifecycle.	Blocks of data that are used for error checking and correction in a storage system.

A storage technology that uses parity blocks to improve data reliability and performance.	A value calculated from the data to verify its integrity and detect errors.
A technique where data is divided into blocks and stored across multiple disks, including parity blocks.	The ability of a system to continue functioning properly in the event of hardware or software failures.
The additional storage space required to store parity blocks, reducing the overall usable capacity of a RAID system.	The process of deriving parity information from the data blocks.
a cyclic redundancy check algorithm used to detect accidental changes or errors in data	a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value

A technique used in computer networks to handle lost or corrupted data packets by retransmitting them automatically.	The process of verifying the integrity of network data by sending a request packet and comparing the echoed response packet.
Information sent from the receiver to the sender to indicate whether data packets have been successfully received or not.	The process of resending data packets that have been lost or corrupted during transmission.
A signal sent by the receiver to inform the sender that data packets have been successfully received.	The failure of one or more data packets to reach their destination due to factors like network congestion or transmission errors.
A unique identifier assigned to each data packet to ensure correct ordering and detect duplicate packets.	The period of time after which a sender assumes that a data packet has been lost and triggers retransmission.

A mathematical formula used to validate a variety of identification numbers.	A digit added to a number to help detect errors.
