Across
- 6. The type of signaling where each bit of data is represented by pulse of electricity or light which as sent at a single fixed frequency.
- 7. This topology is an extension of the star topology by introducing multiple central hubs or switches.
- 8. Signal experiences this as it travels across network media.
- 10. The result of two or more devices communicating on the same medium simultaneously.
- 11. Abbreviation of the name given to 802.11 IEEE standards.
- 14. The amount data in a network transmission that is not the application data.
- 15. A public Wi-Fi network without encryption or authentication.
- 17. The operational mode of wirelessly connecting two LANs when a physical connection is impractical.
- 18. The result of electrical signals bouncing off the end of a cable, also known as reflection.
- 20. The actual amount of data transferred.
Down
- 1. The ratio that measures the valid signal against the amount of noise in a network.
- 2. Defined by IEEE 802.3u, this is the most commonly used Ethernet today running over Cat 5 or higher cable.
- 3. Defined by IEEE 802.3an, runs 10 Gigabit Ethernet on Cat 6A cable and only operates in full-duplex mode.
- 4. The physical arrangement of networking devices and cables in a network.
- 5. This topology uses a central device that connects to each computer in the network.
- 9. Signals that are copied because of reflection and scattering and that arrive at the receiver at different times.
- 12. The name of the actual application-to-application data transfer speed.
- 13. This topology is when each device is connected to every other device in a network.
- 16. The electrical component usually a resistor placed at the end of a physical bus to stop signal bounce.
- 19. This topology uses a continuous length of cable to daisy-chain computers together.
