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