Step-by-step explanation:
1. Networks can be classified by geographical scope as PANs, LANs, and WANs.
2. The cables and signals used to transport data from one network device to another are a communication channel.
3. Wired channels include twisted pair wires, coaxial cables used for cable television, and fiber-optic cables used for high-capacity trunk lines.
4. Wireless channels use RF signals and microwaves. Government agencies regulate some wireless channels.
5. The transmission capacity of a channel is referred to as bandwidth.
6. Channels that are capable of moving at least 25 Mbps are classified as broadband.
7. Networks can be configured in various topologies, such as star, mesh, point-to-point, or bus.
8. Any device in a network is referred to as a node.
9. Data terminal equipment includes computers.
10. Data communication equipment includes modems and routers.
11. Additional DCEs include hubs, switches, bridges, repeaters, and WAP access points.
12. Networks use physical, transport, and arrival communication protocols to set the rules for efficiently transmitting data and handling errors.
