Final answer:
Armored cable is also referred to as shielded cable, which is designed to protect against both physical damage and electromagnetic interference. Coaxial cables are a type of shielded cable.
Step-by-step explanation:
Armored cable is often referred to as shielded cable. This type of cable is designed to protect the conductors inside from physical damage and electromagnetic interference (EMI). Coaxial cables are an example of shielded cables, featuring an inner conductor surrounded by an insulating layer and enclosed by a shield, which is often a braided metal. This construction helps minimize noise and interference that could affect the signal quality. However, the term armored implies additional protection, which may include metal cladding or a robust external layer to protect against mechanical stresses, rather than just EMI.
