The additional devices such as hubs or switch increase the overall cost.
The addition of more nodes depends on the capacity of the central device.
Reconfiguration, fault isolation and installation of new devices tend to be difficult.
2. Bus Topology: It has a common cable to which all the computers on the network are linked. The common cable usually terminated at each end. One or more of the station on the network acts as the file server. An example of the bus system is the ETHERNET.
The failure of one node does not affect the rest of the bus network.
Flexibility of nodes is visible as they can be attached or detached without any problem.
Troubleshoot is easier compared with ring topology.
3. Ring Network: It uses one network cable to connect all the workstation in an arrangement that looks like a ring. Ring networks are less secure because data intended for a particular machine may have to pass by other machines before it gets to its destination in the network.
