9. cable consists of a single copper wire surrounded by at least three layers.
10. is basically a microwave station placed in outer space.
13. does not broadcast the data to all the computers, it sends the data packets only to the destined computer.
14. telecommunications technologies transport digital communications without cables between communications devices.
15. transmission transmits one byte at a time over a line at random intervals.
17. is a device that provides a central point for cables in a network.
19. a device that accepts a signal from a transmission medium, amplifies it, and retransmits it over the medium.

1. signal is a series of discrete bits.
3. transmission sends data in one direction only.
5. This is the process through which the signals are converted back into the information in its original form in the receiving device.
6. transmission allows data transmission in either direction, but only one way at a time.
8. data can flow in both directions at the same time.
10. transmission transmits groups of bytes simultaneously at regular intervals.
11. This is the process through which the signals are broad cast
12. When a computer sends data over the Internet, the data is divided into small pieces called
16. connects multiple networks and routs communications traffic to the appropriate network
18. central computer that manages the resources on a network.
