Across

1. The ability of a system to continue functioning properly in the event of hardware or software failures.

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

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

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

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

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

7. Bits added to binary data to ensure an even or odd count of 1s.

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

9. A signal sent by the receiver to inform the sender that data packets have been successfully received.

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

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

Down

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

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

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

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

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

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