Step 1: Understanding broadband internet services.
Broadband refers to high-speed internet connections that enable continuous data transmission and fast service across extensive geographical regions.
Step 2: Evaluating each option.
- Option 1: LAN (Local Area Network): A LAN connects devices within a limited area, such as a single building, and is not typically used for broadband internet services. - Option 2: MAN (Metropolitan Area Network): A MAN covers a larger area than a LAN, typically a city or large campus. While it might offer broadband services, it is not suited for individual broadband internet connections. - Option 3: WAN (Wide Area Network): A WAN spans vast geographical areas, often across countries or continents. Cable-based broadband internet services commonly utilize WAN connections. - Option 4: PAN (Personal Area Network): A PAN connects devices within a very small radius, usually a few meters, and is irrelevant to broadband internet services.
Step 3: Conclusion.
Cable-based broadband internet services operate over WAN, making it the appropriate choice.
Final Answer: \[\boxed{\text{Cable-based broadband internet services are an example of WAN.}}\]
