What is an advantage of using coaxial cable compared to other types?

It is lightweight and portable
Larger bandwidth capacity
Resistance to interference
Integration with fiber optics

The correct answer is: Resistance to interference

One of the significant advantages of using coaxial cable compared to other types of cabling is its resistance to interference. Coaxial cable is designed with a central conductor surrounded by a layer of insulating material, a metallic shield, and an outer insulating layer. This construction helps to shield the electrical signals being transmitted from external electromagnetic interference (EMI) and radio frequency interference (RFI). As a result, coaxial cables can maintain better signal integrity over longer distances, which makes them particularly suitable for applications where minimizing signal degradation is crucial, such as in television signal transmission or broadband internet connections. This ability to resist outside interference helps improve overall network performance and reliability. While other types of cables, like twisted pair or fiber optic cables, have their own advantages, they do not provide the same level of protection from interference that coaxial cables offer. Therefore, it's this unique shielding capability that stands out when considering the advantages of using coaxial cable.
