| Acknowledgment |
A signal sent by the receiver to inform the sender that data packets have been successfully received. |
| Automatic Repeat Query |
A technique used in computer networks to handle lost or corrupted data packets by retransmitting them automatically. |
| CRC |
a cyclic redundancy check algorithm used to detect accidental changes or errors in data |
| Capacity Overhead |
The additional storage space required to store parity blocks, reducing the overall usable capacity of a RAID system. |
| Check Digit |
A digit added to a number to help detect errors. |
| Checksum |
A value calculated from the data to verify its integrity and detect errors. |
| Data Integrity |
The assurance that data remains accurate, consistent, and complete throughout its lifecycle. |
| Echo Check |
The process of verifying the integrity of network data by sending a request packet and comparing the echoed response packet. |
| Error Correction |
The process of detecting and correcting errors that occur during data transmission or storage using error correction codes. |
| Error Detection |
The process of detecting and correcting errors that occur during data transmission or storage. |
| Even Parity |
A method of error detection where the number of 1s, including the parity bit, is always even. |
| Fault Tolerance |
The ability of a system to continue functioning properly in the event of hardware or software failures. |
| Feedback |
Information sent from the receiver to the sender to indicate whether data packets have been successfully received or not. |
| Luhn Algorithm |
A mathematical formula used to validate a variety of identification numbers. |
| Md5 |
a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value |
| Odd Parity |
A method of error detection where the number of 1s, including the parity bit, is always odd. |
| Packet Loss |
The failure of one or more data packets to reach their destination due to factors like network congestion or transmission errors. |
| Parity Bits |
Bits added to binary data to ensure an even or odd count of 1s. |
| Parity Blocks |
Blocks of data that are used for error checking and correction in a storage system. |
| Parity Calculation |
The process of deriving parity information from the data blocks. |
| RAID |
A storage technology that uses parity blocks to improve data reliability and performance. |
| Redundancy |
The inclusion of extra information or resources in a system to improve reliability and provide backup in case of failures. |
| Retransmission |
The process of resending data packets that have been lost or corrupted during transmission. |
| Sequence Number |
A unique identifier assigned to each data packet to ensure correct ordering and detect duplicate packets. |
| Striping |
A technique where data is divided into blocks and stored across multiple disks, including parity blocks. |
| Timeout |
The period of time after which a sender assumes that a data packet has been lost and triggers retransmission. |
