Network really has two shapes, or two types of topology; one is physical and the other is logical. The physical topology is the shape you can see, and the logical topology is the shape that the data travels in. Physical Topologies Physical topology is further divided in two section · Point-to-point connections · Multipoint connections Point-to-point connections Only two devices are involved in a point-to-point connection, with one wire (or air, in the case of wireless) sitting between them.
