worn wire jackets, crushed wires that touch, and pierced wires that
touch metal.
What is CROSSTALK? -
correct answer ✅Interference that is caused by signals within
twisted pairs of wires.

correct answer ✅The loss of signal strencth from one end of a
cable to the other caused by distance.
What is a split pair condition? -
