Across
- 5. the actual data being carried in a data packet
- 8. a type of encryption key that is known to all users
- 9. the time interval allowed to elapse before an acknowledgement is received[in the ARQ error detection method
- 10. data that arrives at the destination with the bits no longer synchronised
Down
- 1. a bit 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. staged in a network that can receive and transmit data packets; routers are nodes in communication networks
- 3. a horizontal and vertical parity check on a block of data being transmitted
- 4. the original text/message before it is put through an encryption algorithm
- 6. data that can be sent on one direction only
- 7. a type of encryption key which is known only to the single computer/user
