Final answer:
STP (Shielded Twisted Pair) cable contains multiple copper wires and uses extra shielding to prevent interference from nearby electronic devices.
Step-by-step explanation:
The network cable that contains multiple copper wires and uses extra shielding to prevent interference is STP (Shielded Twisted Pair) cable.
STP cables have an additional layer of protective shielding made of metal or foil to reduce electromagnetic interference from nearby electronic devices, which can interfere with the transmission of data signals.
On the other hand, UTP (Unshielded Twisted Pair) cables do not have this extra shielding, making them more susceptible to interference.
