Which one of the following requires phone line but offers faster access speed than the dial up connection?

  • A.Digital subscriber line (DSL)
  • B.Cable access
  • C.Fibre optic serving
  • D.Modem

Answer: A

Correct answer: Digital subscriber line (DSL)

DSL uses the same copper pair as the telephone but transmits at frequencies above the voice band, so it is far faster than a dial-up modem and the line remains usable for calls. Cable and fibre are faster still but do not use the phone line.
