Across

1. The process of detecting and correcting errors that occur during data transmission or storage using error correction codes.

2. A unique identifier assigned to each data packet to ensure correct ordering and detect duplicate packets.

3. The inclusion of extra information or resources in a system to improve reliability and provide backup in case of failures.

4. A technique used in computer networks to handle lost or corrupted data packets by retransmitting them automatically.

5. A value calculated from the data to verify its integrity and detect errors.

6. A method of error detection where the number of 1s, including the parity bit, is always odd.

7. The assurance that data remains accurate, consistent, and complete throughout its lifecycle.

8. A storage technology that uses parity blocks to improve data reliability and performance.

9. The process of verifying the integrity of network data by sending a request packet and comparing the echoed response packet.

10. The period of time after which a sender assumes that a data packet has been lost and triggers retransmission.

11. A method of error detection where the number of 1s, including the parity bit, is always even.

Down

12. A technique where data is divided into blocks and stored across multiple disks, including parity blocks.

13. The process of resending data packets that have been lost or corrupted during transmission.

14. Blocks of data that are used for error checking and correction in a storage system.

15. A digit added to a number to help detect errors.

16. The process of deriving parity information from the data blocks.

17. The failure of one or more data packets to reach their destination due to factors like network congestion or transmission errors.

18. The additional storage space required to store parity blocks, reducing the overall usable capacity of a RAID system.
