STAR TOPOLOGY
In this topology, all devices are attached to a central point, which is sometimes known as the "Hub" as given in the diagram below.
Figure: An idealized star network
It is very important to show that these networks are not physically like stars but they are seems like stars. It defines that their shape does not seems like a star but their connections are just same as a star. The above figure is idealized. Here is given a star network in practice in the diagram below:
