12. Refer to the graphic. What type of cabling is shown?
- STP
- UTP
- coax
- fiber
Explanation: Network cabling include different types of cables:
- UTP cable consists of four pairs of color-coded wires that have been twisted together and then encased in a flexible plastic sheath.
- STP cable uses four pairs of wires, each wrapped in a foil shield, which are then wrapped in an overall metallic braid or foil.
- Coaxial cable uses a copper conductor and a layer of flexible plastic insulation surrounds the copper conductor.
- Fiber cable is a flexible, extremely thin, transparent strand of glass surrounded by plastic insulation.
