5. The transmission capacity of a channel is referred to as <u>bandwidth</u>.
6. Channels that are capable of moving at least 25 Mbps are classified as <u>broadband</u>.
7. Networks can be configured in various <u>topologies</u>, such as star, mesh, point-to-point, or bus.
8. Any device in a network is referred to as a <u>node</u>.
9. Data <u>terminal</u> equipment includes computers.
10. Data <u>communication</u> equipment includes modems and routers.
11. Additional DCEs include hubs, switches, bridges, repeaters, and <u>WAP</u> access points.
12. Networks use physical, transport, and arrival communication <u>protocols</u> to set the rules for efficiently transmitting data and handling errors.
