What is star topology?

In a star network, all computers or nodes are directly connected to a central device. The central device is called Hub/Switch. A larger network may consist of many hubs/switches. All the hubs or switches in the network are connected to each other. Different computers or nodes are connected to each hub. Usually, the nodes are connected to the Hub with unshielded twisted pair (UTP). Star topology is most commonly used in LAN. This form of network shape looks like a Star.
