In multipoint connection more than two specific devices share a single link. Here the capacity of the channel is shared either separately or temporally.

It is the mode of communication between two devices in which flow of data is unidirectional.

It is the mode of communication between two devices in which flow of data is bidirectional but not at the same time. ie each station can transmit and receive but not at the same time.

It is the mode of communication between two devices in which flow of data is bidirectional and it occurs simultaneously. Here signals going in either direction share the capacity of the link.

Topology of a network is defined as the geometric representation of the relationship of all the links and linking devices (node) to one another .
