PHYSICALLOGICAL
  • A cable forms a closed loop (ring) with all the computers and devices arranged along the ring .
ring
  • Transmit data from one device to another device in one direction .
  • Token passing :
            - when a computer receives a token , the token will pass each  computer on the ring until it reaces it destination.
            - only one device with the token is allowed to send data.

ADVANTAGES DISADVANTAGE
  1. No collision of data can happen because only 1 node is allowed to send data at one time (token passing) .
  2. Simple data transmission because data travels in one direction only .
good1
    1.  If one node fails , the entire network will be down .
    2. Difficult to add new nodes as it requires the network to be  disrupted .
