Across
- 4. the actual data being carried in a data packet
- 6. a bit (either 0 or 1) added to a byte of data in the most significant bit position; this ensures that the byte follows the correct even parity or odd parity protocol (2 words)
- 7. data that can be sent on one direction only
- 8. the process of making data meaningless using encryption keys; without the correct decryption key the data cannot be decoded
Down
- 1. data that arrives at the destination with the bits no longer synchronised
- 2. a type of encryption key which is only to the single computer/user
- 3. a device that enables data packets to be moved between different networks, for example to join LAN to a WAN
- 5. the time interval allowed to elapse before an acknowledgement is received correctly
- 6. a horizontal and vertical parity check on a block of data being transmitted (2 words)
- 9. a type of encryption key that is known to all users (2 words)
