Question

which of the following statements is true of twisted - pair cables?
shielded twisted - pair cables are more susceptible to interference than unshielded twisted - pair cables.
they are usually made up of a glass or plastic fiber, a cladding, and a protective sheath.
twisted - pair cables that contain a layer of foil shielding are called coaxial cables.
the twists reduce the amount of crosstalk interference.
i dont know yet

Explanation:

• Analyze each option:
• First option: Shielded twisted - pair (STP) has shielding, so it's less susceptible to interference than unshielded twisted - pair (UTP). So this is false.
• Second option: The description is for fiber - optic cables, not twisted - pair cables. So this is false.
• Third option: Twisted - pair cables with foil shielding are STP, and coaxial cables have a different structure. So this is false.
• Fourth option: The twisting of the pairs in twisted - pair cables is done to reduce crosstalk (a type of interference between adjacent wires). So this statement is true.

Answer:

The option "The twists reduce the amount of crosstalk interference." (the fourth option among the given choices)
