Non-polling system is

  • A.TDMA
  • B.stop and wait
  • C.continuous ARQ
  • D.none of these

Answer: A

Correct answer: TDMA

In TDMA each station has its own time slot and transmits in it without being asked, so no station has to be polled. Stop-and-wait and continuous ARQ are error-control schemes rather than access methods.
