Which of the following is possible in a token passing bus network ?

  • A.in-service expansion
  • B.unlimited number of stations
  • C.both (a) and (b)
  • D.unlimited distance

Answer: A

Correct answer: in-service expansion

A token bus passes the token logically, by address, rather than physically round a cable, so a station can be added to or removed from the logical ring while the network keeps running. The number of stations and the span are both limited by the medium.
