● Traditional Internet access methods like dial-up were so slow that host computers wereconnected to the dial-up （71） at the customer premise over slow （72） ports. PPP wasdesigned to run directly over these serial links. But with the advent of broadband Internet （73）technologies such as ADSL and cable modems there has been a considerable increase in thebandwidth delivered to the end users. This means that the host computers at the customerpremise connect to the （74） or cable "modem" over a much faster medium such as Ethernet.It also means that multiple （75） can connect to the Internet through the same connection.

A. Computer> cable modem > router

B. Cable modem> router> computer

C. Cable modem> computer> router

D. Router> cable modem> computer
