Best Answer

A internel modem in a computer can be used for a dial-up connection service from your ISP. A external modem is used for dial-up, DSL (Digital Subscriber Line), and cable internet.

Dial-up = Phone line

DSL = Phone line (generally faster and does not cut out your calls)

Cable Internet = TV line
