What is the primary type of connection used by a cable modem?

A cable modem primarily uses a Cable TV connection for data transmission. This technology leverages the same coaxial cables that deliver television signals to homes. The advantage of using this type of connection is its ability to provide high-speed internet access by utilizing the existing infrastructure of cable television networks.

Cable modems convert the digital data from a computer into signals that can be sent over these coaxial cable lines and vice versa, allowing for efficient two-way communication. The reliability and bandwidth capacity of cable connections make them suitable for providing internet services, so they are widely deployed in residential and commercial environments.

Other connection types mentioned, such as DSL, Fiber Optic, and Satellite, utilize different technologies and infrastructure. DSL uses telephone lines, Fiber Optic uses light transmitted through fiber cables, and Satellite relies on signals sent to and from satellites, each having distinct advantages and limitations compared to cable connections.
