What type of internet connection is provided through cable television infrastructure?

• A. Cable modem
• B. DSL
• C. Satellite
• D. Cellular network

Answer: (A)

The type of internet connection provided through cable television infrastructure is known as a cable modem. This technology leverages the existing coaxial cable lines that deliver television service to homes, utilizing the bandwidth that is not being used for cable TV signals. Cable modems connect to these lines and allow data to be transmitted over the same infrastructure used for cable television. This system enables high-speed internet access, making it a popular choice among consumers.

The other options represent different types of internet connectivity. DSL (Digital Subscriber Line) uses existing telephone lines for internet access, satellite internet relies on signals sent to and from satellites, and cellular networks provide mobile internet through cell towers. However, none of these utilize cable television infrastructure, which specifically pertains to cable modems.
