What term describes copper wiring twisted together and coated with electromagnetic insulation?

Explanation:
Shielded Twisted Pair is the description that fits. It refers to copper conductors arranged as twisted pairs and wrapped with a shielding layer (like foil or braided metal) to block external electromagnetic interference. The twists help with noise rejection and reduce crosstalk, while the shielding adds an extra barrier against EMI. The other options describe connectors (RJ11 and RJ45) or a type of cable that has no shielding (Unshielded Twisted Pair). So the combination of twisted wiring plus shielding is precisely Shielded Twisted Pair.
