  1. 3. is a grade of cable suitable for data networking.
  2. 4. Representing 0s and 1s as a physical signal, such as electrical voltage or a light pulse the method used to represent bits on a medium.
  3. 8. Intermediate distribution frame.
  4. 9. is a length of cable between two network devices, such as a NIC and a switch.
  5. 12. This device broadcasts messages in wireless format that must be directed to wireless users and relays messages sent by wireless users to resources or users on the wired side of its connection.
  6. 14. The collection of all cables and connectors tying a network together.
  7. 18. The location of workstations and other user devices-in short, the place where people work with computers and other network devices.
  8. 19. use low-powered, two-way radio communication, much like what’s used in taxis, police radios, and other private radio systems
  9. 20. Interference that one wire generates on another wire when both wires are in a bundle.

  1. 1. wireless networks use infrared light beams to send signals between pairs of devices
  2. 2. is a short cable for connecting a computer to an RJ-45 jack or connecting a patch-panel port to a switch.
  3. 5. The attachment of RJ-45 plugs on a cable to make a patch cable, or punching down cable wires into terminal blocks on a jack or patch panel.
  4. 6. is a grade of cable that's not suitable for data networking but is suitable for voice communication.
  5. 7. main distribution frame.
  6. 10. medium dependent interface.
  7. 11. comes in two types: unshielded and shielded (UTP and STP). It consists of one or more pairs of insulated strands of copper wire twisted around one another and housed in an outer jacket or sheath
  8. 13. Devices that use infrared signals to communicate. IrDA stands for infrared Device Association.
  9. 15. The frequency of the wave forms used for communication is measured in cycles per second, usually expressed as
  10. 16. which is interference one wire generates on another wire when both are in a bundle as all cabling in LANs is).
  11. 17. an organization might use wireless components to increase a LAN’s span beyond normal distance limitations
