Bus topology

1) Bus topology

In bus topology, every network device hook directly into a central cable because there is no use of central devices like a hub, switch, repeater etc. So every device is connected to the central wire (acts as a central hub). So the central cable is shared communication medium for every device that tap into it. When the device communicates across the cable, the message is seen by all the other devices, but only the true destination devices will use it.

Benefits of Linear Bus Topology

1)  It is easy to install and extend bus network.
2)  Cable length required for this topology is the least compared to other networks.
3)  Bus topology costs very less than other topology.
4) This types of network is mostly used in small networks. Good for LAN.

Disadvantages of Linear Bus Topology

1)  There is a limit on central cable length and number of nodes that can be connected.
2)  Dependency on central cable in this topology has its disadvantages. If the main cable  encounters
     some  problem, whole network breaks down.
3)  Proper termination is required to dump signals. Use of terminators is must.
4)  It is difficult to detect and troubleshoot fault at individual station.
5)  Maintenance costs can get higher with time.
6)  Efficiency of Bus network reduces, as the number of devices connected to it increases.
7)  This types of network is not suitable for networks with heavy traffic.
