CSMA/CD offers a method that organizes data transmission properly. sha roe clonegalWebThe importance of the token ring topology is, the source sends an empty token with a message and address of the destination. So the token checks for the successive node i.e. address of computer/ host. When the token identifies the node, the receiver copies the data and returns with a receipt containing the source’s address. population of patna
