Across

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

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

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

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

5. The process of detecting and correcting errors that occur during data transmission or storage.

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

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

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

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

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

Down

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

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

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

14. A mathematical formula used to validate a variety of identification numbers.

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

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

17. Information sent from the receiver to the sender to indicate whether data packets have been successfully received or not.
