The logical topology in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices.' The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits.
This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The shape of the cabling layout used to link devices is called the physical topology of the network. 'There are two basic categories of network topologies: The vector stencils library 'Cisco network topology' contains 89 symbols of Cisco network devices and design elements for drawing computer network topology diagrams.
