Which of the following provide an “always on” Internet access service when connecting to an
ISP?Each correct answer represents a complete solution. Choose two.

Explanation:

DSL and Cable modems are used in remote-access WAN technology for connecting to the
Internet. Both provide an “always on” Internet access service.

when connecting to an ISP. Analog modems transmit analog voice signals, while Digital modems
transmit digital signals over a link.
