I want to know the answer to the following question:
who is served by dial-up, dsl, adsl, cable modems, or isdns?
All the background I'm provided with is that "For users and small businesses, traditional options include copper wires to provide dial-up, DSL, typically asymmetric digital subscriber line (ADSL), cable modem or Integrated Services Digital Network (ISDN) (typically basic rate interface).". Is that enough to answer the question?
Answer: yes
