Which internet service is delivered without physical cables, using radio waves?

• A. Fiber optic
• B. Cable
• C. Digital subscriber line (DSL)
• D. Wireless

Answer: (D)

Wireless internet is delivered without physical cables by using radio waves to transmit data between devices and network access points or towers. This means the signal travels through the air instead of through fiber, copper, or coax cables, which enables mobility and easy deployment in areas without wired infrastructure. Examples include Wi‑Fi inside homes, cellular data networks (4G/5G), fixed wireless connections from a tower to a dish, and satellite connections. Fiber optic relies on glass or plastic cables carrying light signals; cables carry the data physically. Cable service uses coaxial cables to bring internet to your location. DSL runs over existing copper telephone lines. Each of these requires a physical path to your premises, unlike wireless.
