What advantage does a cable modem provide for internet access?

A cable modem offers the advantage of higher bandwidth and faster connection speeds compared to dial-up by utilizing the existing cable television infrastructure to provide internet access. Cable modems can transmit large amounts of data simultaneously thanks to the wider channels available in cable networks, allowing for quicker download and upload times, which is especially beneficial for activities such as streaming video, online gaming, and downloading large files. This performance is a significant upgrade over dial-up connections, which are limited by their lower bandwidth and the need to use traditional phone lines, leading to slower data transmission speeds.

The other options, while they may highlight relevant aspects of internet services, do not accurately reflect the primary benefit of a cable modem in comparison to dial-up services.
