Question

what is the main drawback of dsl internet? high cost limited availability signal attenuation over distance requires special equipment

Explanation:

DSL (Digital Subscriber Line) transmits data over telephone lines. The signal quality degrades as the distance from the service provider's central office increases. This is a fundamental characteristic of DSL technology based on the physical properties of the transmission medium (telephone lines). Cost is relatively moderate compared to some other high - speed options. Availability is not as limited as some older technologies. And while a DSL modem is needed (which could be seen as'special equipment'), it's a common and not overly burdensome requirement. Signal attenuation over distance is a more inherent and significant drawback.
