Which service allows television or radio reception directly from satellites?

The correct answer is the service that allows television or radio reception directly from satellites, which is Direct Broadcast Satellite (DBS). DBS technology utilizes satellites in geostationary orbit to transmit signals directly to a subscriber's satellite dish, enabling them to receive television programming without the need for cable lines or terrestrial broadcasting. This method provides significant advantages, including a wide range of channels and access to programming in areas where traditional cable service may not be available.

In contrast, other options involve different methods of delivering media content. Digital Subscriber Line (DSL) uses telephone lines for high-speed internet access, which doesn't pertain to satellite reception. Cable Modem Service relies on coaxial cable networks for internet and television delivery, again not connected to satellite technology. Fiber-optic Broadcasting employs fiber-optic cables to transmit data at high speeds, but it does not involve satellite signals. Therefore, the distinctive capability of DBS to provide satellite-based signals directly to viewers makes it the correct choice.
