How does a cable modem differ from a DSL modem?

The distinction between cable modems and DSL modems primarily lies in the type of infrastructure they utilize for internet connectivity. Cable modems transmit data over coaxial cable lines, which are the same lines that deliver cable television signals. In contrast, DSL (Digital Subscriber Line) modems operate over traditional telephone lines. This difference in infrastructure not only influences the technology used but also affects the speed and reliability of the internet services provided by each type of modem.

Cable modems generally have the capacity for higher speeds than DSL due to the wider bandwidth of cable networks. While the other choices mention various comparisons, the fundamental and correct aspect of the difference is based on the types of lines used by each modem type for internet connectivity. Understanding this distinction helps in selecting the appropriate modem based on service availability and required internet speed.
