Across 3. This type of signal uses values from a discrete set 4. Vary a carrier signal using information to be transmitted 6. The path the signal travels from transmitter to reciever 7. A physical quantity which varies with time/space and carries information 9. Technique where parts of a message are routed independently through the network (2 words) 10. Refers to the information transfer capacity of a transmission medium 11. A modulation technique that transmits an analog signal as a digital bit stream (2 words) 16. Tells the nodes how the message is to be routed through the network (2 words) 17. A circuit is set up between two nodes for the duration of the communication session (2 words) 18. Analog has a poor response to this, that's why digital is preferred for transmission

Down 1. This type of signal uses a continuous range of values 2. The complete path between two communicating terminals 5. Exchange of information over significant distances 8. Used as a basis for dividing an analog medium into logical channels to transmit multiple message streams 9. A set of message formats and rules for sending information 10. The actual content of the message that is sent by the user (2 words) 12. Component that converts information to a signal 13. Combine more than one message streams and transmit them over a shared channel 14. Collection of terminals, nodes and links that enable communications between users 15. Component that carries the signal from transmitter to receiver
