What is one advantage of digital subscriber line (DSL) Internet service?

One advantage of digital subscriber line (DSL) Internet service is that it tends to have a very consistent signal. DSL technology operates over traditional telephone lines, allowing for a dedicated connection directly to the user's location. This results in relatively stable performance, as the signal is less susceptible to interference from external factors compared to some other technologies.

The quality of service may remain more consistent because users typically don't share bandwidth with neighbors, unlike in some cable Internet services where multiple users are connected to the same node. Consequently, DSL can provide more reliable speeds for tasks such as streaming or gaming, where a steady connection is crucial.

The other options do not accurately represent DSL's characteristics. DSL is not wireless; it requires a physical connection through telephone lines. It also does not utilize fiber-optic cables, which are more commonly associated with fiber-optic Internet services. While DSL can offer good speeds, especially in newer implementations, it generally does not exceed the maximum speeds available through cable Internet options.
