Final answer:
The correct answer is d) Electromagnetic shielding. UTP cables do not have electromagnetic shielding, making them more susceptible to signal interference from external sources.
Step-by-step explanation:
The correct answer is d) Electromagnetic shielding. Unshielded twisted pair (UTP) cabling does not have electromagnetic shielding, unlike shielded twisted pair (STP) cabling. UTP cables are commonly used for Ethernet connections in homes and offices. They are generally less expensive and easier to install compared to STP cables. However, one downside of UTP cables is that they are more susceptible to signal interference from external sources, such as nearby electrical wires or radio waves.
