In this topology, two nodes are usually placed near each other. The node can also be a router or hub. In the case of a router or hub, one connection is made between a computer and a router, hub or switch.

The communication between two nodes can be either simplex, half-duplex or full-duplex. In the simplex mode of communication, only one node can send data. In half-duplex, both devices (nodes) can send data but one at a time. In full-duplex, both devices can send data at a time.

The medium to make a connection can be either microwave-based, dedicated fibre or leased line.
