Which of the following is a characteristic of cable Internet service?

Cable Internet service uses the same coaxial cables that are utilized for cable television. This infrastructure allows for high-speed Internet access by leveraging the bandwidth available in the coaxial cable, which is designed to carry a large amount of data. The technology used in cable modem services can deliver faster speeds than many other types of broadband services, including DSL. This connectivity advantage is largely due to the capability of coaxial cables to handle higher frequencies, allowing for greater data transmission rates.

The option regarding fiber-optic cables is not applicable, as cable Internet specifically relies on coaxial cable, not exclusively fiber optics. While some Internet providers utilize fiber-optic services, they are distinct from traditional cable service. The assertion that cable Internet offers slower speeds than DSL is also misleading; in many cases, cable provides faster service than DSL, particularly in urban areas where cable infrastructure is well-developed. Lastly, the installation complexity of cable Internet can vary but is generally simpler than DSL in terms of equipment and existing infrastructure, further highlighting why the other choices do not accurately describe cable Internet service.
