As a bridge, it forwards data between the networks. The advantage of the star topology is that if a link breaks then only that particular link is affected. Ring topology is a network topology in which nodes are exactly connected to two or more nodes and thus, forming a single continuous path for the transmission. The main disadvantage of the star topology is that all the devices of the network are dependent on a single point (hub). Answer: Open System Interconnection, the name itself suggests that it is a reference model that defines how applications can communicate with each other over a networking system.
