coaxial cable - CORRECT ANSWER- Cabling with a central metallic inner conductor and a
separated enclosed outer conductor by a dielectric material like a metallic braid
Crosstalk - CORRECT ANSWER- Unwanted transfer of a signals electromagnetic energy
(blue interfering with orange)
Impedance (Z) - CORRECT ANSWER- The total opposition that a circuit cable or compound
offers to the flow of altering current (measured in ohms)
