  1. The device that bridges wireless networking components and a wired network.
    Access Point Device
  2. Hardware devices that increase the power of electrical signals to maintain their original strength when transmitted across a large network.
  3. The method of signal transmission used on broadband networks.
  4. A 2.5 Mbps LAN technology that uses token-based networking technology and runs over several kinds of coaxial cable, twisted pair, and fiber-optic cable.
    Attached Resource Computing Network (ARCnet)
  5. The weakening of a signal as it travels the length of a medium, which eventually causes the signal to be unreadable.
  6. The part of the cable plant that interconnects telecommunications closets and equipment rooms.
    Backbone Cabling
  7. The range of frequencies that a communications medium can carry.
  8. A technology that uses digital signals sent over a cable without modulation. It sends binary values as pulses of different voltage levels.
    Baseband Transmission
  9. An analog trasmission technique that can use multiple communication channels simultaneously.
    Broadband Transmission
  10. A special-purpose networking device that permits a computer to send and receive networking signals, primarily for Internet access, by using to data channels on a broadband CATV network.
    Cable Modem
  11. The combination of installed network cables, connectors, patch panels, wall jacks and other media components.
    Cable Plant
  12. A nontransparent layer of glass or plastic material inside fiber-optic cable.
  13. A type of cable that uses a center conductor, wrapped by an insulating layer and surrounded by a braided wire mesh and an outer jacket or sheath, to carry high bandwidth signals.
    Coaxial Cable
  14. A phenomenon that occurs when two wires lay against eachother in parallel.
  15. A designation for cabling of any kind.
  16. The use of two wires to carry a signal, where one wire carries a positive voltage signal and the other carries a negative.
    Differential Signal
  17. A broadband technique in which 2 cables are used; one for transmitting and one for receiving.
    Dual-cable Broadband
  18. A form of interference cause by emission from external devices that can disrupt network transmissions over an electrical medium.
    Electromagnetic Interference (EMI)
  19. The capability to "listen" to signals passing through a communications media by detecting its emissions.
    Electronic Eavsdropping
  20. An industry trade group of electronics and networking manufacturers that collaberates on standards for wiring, connectors and other common components.
    Electronic Industries Alliance
  21. The location of the cabling and equipment taht connects a corporate network to a third party telecommunications provider.
    Entrance Facility
  22. An area that serves as a connection point for backbone cableing running between telecommunications closets
    Equipment Room
  23. A cabling technology that uses pulses of light sent along a light-conducting fiber at the heart of the cable to transfer information from sender to receiver.
  24. An orbital position relative to Earth where a satellite orbits at the same speed as Earth rotates.
  25. The weakening of signlas that occurs on a cable segment each time a network device is attached.
    Insertion Loss
