Across
  1. 1. A type of encryption key known only to the user or device, used for decrypting data
  2. 3. A one-way data transmission method, such as from a computer to a printer
  3. 7. The result of the encryption process, representing the encrypted data
  4. 10. The process of converting plaintext into ciphertext
  5. 11. A medium for transmitting data using light, known for high speed and long-distance communication
  6. 12. A cryptographic key used for encrypting data, which can only be decrypted with a corresponding private key
  7. 15. The section of a packet that contains routing information, including the IP address
  8. 21. An error-checking method similar to a checksum but typically involves more bits for improved accuracy
  9. 23. A method of data transmission where data is divided into packets sent separately through the network
  10. 24. A transmission method allowing data to flow in both directions but not simultaneously
  11. 25. Any device in a network that can send and receive data packets
  12. 27. A device that forwards data packets between networks, effectively directing internet traffic
  13. 28. A method where both sender and receiver can transmit and receive messages at the same time
  14. 29. An error-checking technique that adds an extra bit to data, verified upon receipt
  15. 30. The final digit in a code, calculated from all preceding digits to verify accuracy
Down
  1. 2. An error-checking mechanism that includes a timeout system to resend data if errors occur
  2. 4. An unauthorized entity that intercepts and attempts to decipher encrypted communications
  3. 5. A method that transforms plaintext into an encrypted string, known as ciphertext
  4. 6. A unique identifier for books, often encoded in a barcode
  5. 8. The actual data contained within a data packet
  6. 9. An error-checking method that assesses data integrity based on the number of 1 bits in a byte
  7. 13. A next-generation computing technology that utilizes quantum bits (qubits)
  8. 14. Transmission Sending multiple data channels simultaneously
  9. 16. An error-checking method that can identify transmission errors but not specify their source
  10. 17. An identifier used by a network protocol to locate and communicate with devices on a network
  11. 18. A count that decreases by one each time a packet leaves a router
  12. 19. Data that arrives unsynchronized
  13. 20. The part of a packet that includes error-checking information
  14. 22. The most common input/output interface for computers
  15. 26. Small units of data that are broken up for easier transmission over long distances
