REVIEW 2.1 AND 2.2
Across
- 2. A small network of devices connected via Bluetooth, consisting of one primary and up to seven active secondary devices.
- 3. The number of occurrences of a repeating event per unit of time (measured in Hertz, Hz).
- 5. The process where light, sound, or heat bounces off a surface without being absorbed.
- 7. A LAN that uses wireless technology (Wi-Fi) to connect devices.
- 8. A measure of spatial printing or video dot density; it determines the resolution/clarity.
- 10. The most common type of copper cabling used in Ethernet networks.
- 11. A short-range wireless technology standard used for exchanging data between fixed and mobile devices.
- 14. The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
- 15. A large network that connects smaller networks over long distances, like the Internet.
- 16. A measurement used to determine the speed at which a printer can produce pages.
- 17. The maximum theoretical cable length for a standard UTP Ethernet segment before signal loss occurs.
- 18. A printer that creates images by spraying tiny droplets of liquid ink onto paper.
- 22. A material that allows light to pass through clearly, making objects on the other side easily visible.
- 23. A network that connects users across a specific geographic area, like a city.
- 24. A printer that uses a laser beam and toner (powder) to produce high-quality text and graphics.
- 25. A form of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.
Down
- 1. A material that does not allow any light to pass through it; you cannot see through it.
- 4. The bending of light as it passes from one medium (like air) to another (like water or glass).
- 6. A company that provides individuals and organizations access to the internet.
- 9. Reference to the scientist who was the inventor credited with the first practical telephone. He also made experiments with the twisted pair.
- 12. A network covering a small geographic area, like a single home or office building.
- 13. A Swedish networking and telecommunications company that was instrumental in the invention of Bluetooth.
- 19. A device that forwards data packets between computer networks, directing traffic efficiently.
- 20. A material that allows some light to pass through but scatters it, so objects aren't clearly visible.
- 21. (Light Amplification by Stimulated Emission of Radiation) A device that produces a narrow, intense beam of coherent light.
