  3. 7. data that can be sent on one direction only
  4. 8. the process of making data meaningless using encryption keys; without the correct decryption key the data cannot be decoded
Down
  1. 1. data that arrives at the destination with the bits no longer synchronised
  2. 2. a type of encryption key which is only to the single computer/user
  3. 3. a device that enables data packets to be moved between different networks, for example to join LAN to a WAN
  4. 5. the time interval allowed to elapse before an acknowledgement is received correctly
  5. 6. a horizontal and vertical parity check on a block of data being transmitted (2 words)
