Across
- 5. 100 Mbps Ethernet using baseband signaling that runs Category 5+ UTP cabling using two of four wire pairs. It is the most commonly used Ethernet variety.
- 10. The weakening of a signal as it travels across network media
- 12. ____ ratio; A ratio that measures the amount of valid signal compared with the amount of noise in a network transmission.
- 14. Carrier Sense Multiple Access with Collison____; An access control method used by Wi-Fi networks in which an acknowledgement is required for every packet sent to avoid most possibilities of collision.
- 15. (MU) MIMO; a technology that uses a process called ‘beamforming’ to send data to multiple clients simultaneously
- 18. ____ topology; The path that data travels between computers on a network. The most common logical topologies are switched, bus, and ring.
- 19. extended ____ topology;
- 20. __ __ mode; A wireless mode of operation typically used in small or temporary installations. There’s no central device, so the data travels through one device to another to reach the destination.
Down
- 1. A type of signaling where each bit of data is represented by a pulse of electricity or light that takes over the medium’s entire bandwidth. Common to LAN technologies.
- 2. 100 Mbps Ethernet using baseband signaling over two strands of fiber-optic cabling.
- 3. 10 Gigabit ethernet using baseband signaling that runs over four pairs of Category 6a UTP cabling
- 4. point-to-____ topology; a topology in which a central device communicates with two for more other devices, with all communication going through the central device. It’s often used in WANs.
- 6. The result of electricity bouncing off the end of a cable and back in the other direction. It causes corruption of data as the bouncing signal collides with signals behind it
- 7. Cyclic ____ Check; The error-checking code in an Ethernet frame’s trailer that is calculated pre and post-departure; if the calculation on the destination device doesnt match the calculation in the frame, it indicates the data was altered.
- 8. A type of signaling that moves data through mediums in waves rather than discrete pulses of electricity. Particular frequencies represent a ‘channel’ of data which allows them to stack and carry multiple streams of data on a single wire.
- 9. the amount of information in a network transmission that isn’t part of the application data. This could include headers, acknowledgements, and retransmissions.
- 11. ____ mode; An operational mode for Wi-fi networks in which wireless stations connect through a wireless access point before they can begin communicating with other devices.
- 13. The actual application-to-application speed data transfer speed
- 16. The result of two or more devices on the same medium transmitting simultaneously when CSMA/CD is the media access method in use.
- 17. ____ topology; A network topology in which each device is connected to every other device, providing multiple pathways in the event of a device or cable failure.
