Across
  1. 3. Data arrives at the destination with the bits no longer synchronised
  2. 7. The part of the data packet that indicates the end of the data packet and CRC error check
  3. 8. Data that is sent in both directions at the same time
  4. 9. Sending data down several channels/wires several bits at a time
  5. 12. The part of the data packet that contains the IP address for the sender and receiver, size of packet and packet number
  6. 13. a number in a data packet header used to stop data packets that never reach their destination from clogging up the data paths
  7. 14. Data that is sent in both directions but not at the same time
Down
  1. 1. a device that enables data packets to be moved between different networks
  2. 2. stages in a network that can receive and transmit data packets
  3. 4. a small part of a message transmitted over a network
  4. 5. A method of data transmission in which a message is broken into many data packets which can be sent along pathways independently of each other
  5. 6. data that is sent on one direction only
  6. 10. The actual data being carried in the data packet
  7. 11. Sending data down one channel/wire one bit at a time
