 The following diagram shows an example of a ring network topology, in which each switch or node connects to exactly two other switches, forming a single continuous pathway for the traffic.

 ## Sample: Linear bus and star topology
 
 In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. In the following example, lower switches aren't monitored, and traffic that remains local to these switches won't be seen. Devices might be identified based on ARP messages, but connection information will be missing.
