There are two ways of defining network geometry: the physical topology and the logical (or signal) topology. One can think of a topology as a network's virtual shape or structure. If there’s a problem in the network, It is easy to pin point which connection is defective. The intermediate nodes repeat (re transmit) the data to keep the signal strong. A star topology is a network that is designed to look very similar to a star with a central core and many systems connected directly to that core. This shape does not necessarily correspond to the actual physical layout of the devices on the network. A star topology generally consists of a central hub. There are numerous ways a network can be arranged, all with different pros and cons, and some are more useful in certain circumstances than others. It is called ring topology because it forms a ring as each computer is connected to … when talking about network topology, we’re mostly interested in the bottom few layers. {{{;�}�#�tp�8_\. The way in which the elements of a network are mapped or arranged is known as a network topology. Mesh topology is the kind of topology, in which all the nodes are connected with all … This type of network is easy to install and manage. �������� • The nodes in a network can have following two relationships: 1. It is useful for analyzing complex electric circuits by converting them into network graphs. In a star topology, all the devices are connected to a central device.
