 A star topology is one of the most common network setups where each of the devices and computers on a network connect to a central hub.

 Due to its centralized nature, the topology offers simplicity of operation.  It also achieves an isolation of each device in the network.

 The network operation depends on the functioning of the central hub.  Hence, the failure of the central hub leads to the failure of the entire network.

 A type of network setup where each of the computers and network devices are connected to a single cable or backbone. Below is a visual example of a simple computer setup on a network using the bus topology.

 It is easy to handle and implement.  It is best suited for small networks.

 The cable length is limited.  This limits the number of stations that can be connected.  This network topology can perform well only for a limited number of nodes.

 Also known as a ring network, the ring topology is a type of computer network configuration where each network computer and device are connected to each other forming a large circle (or similar shape). Today, the ring topology is seldom used. Below is a visual example of a simple computer setup on a network using a ring topology.

 The data being transmitted between two nodes passes through all the intermediate nodes.  A central server is not required for the management of this topology.

 The failure of a single node of the network can cause the entire network to fail.  The movement or changes made to network nodes affects the performance of the entire network.
