Network Topologies: Point to Point and Point to Multipoint This lesson covers point to point and point to multipoint topologies. In point to point topology, one device is connected to another device. Point to point topology is sometimes referred to as on link. Point to multi point is when single point goes to multiple points and is used in multicasting. In point to point, things can from point A to point B. However, in multipoint, signals are sent to everyone who is connected.
