What is telecommunication?

What is star topology? Explain.
The topology in which all the nodes are connected through a centrally located device in the form of star is called star topology.
However, the nodes are not under compulsion to be arranged in the form of star but should be directly connected with the network connecting device. It is connected by either switch or hub. The sent data from any nodes first reach to the switch or hub and to the assigned MAC address (nodes).
