Computer Network : Bus Network Topology

A computer network topology is the physical communication scheme used by connected devices. 

Bus Topology is a very simple network topology. All the nodes are connected to the single cable called bus, by the help of interface connectors. This central cable is the backbone of the network and is known as Bus Every workstation communicates with the other device through this Bus. 
It is easy to set-up and extend bus network. Bus topology costs very less. Linear Bus network is mostly used in small networks and it is useful for LAN.
There is a limit on central cable length and number of nodes that can be connected. There is always a Dependency on central cable in this topology. If the main cable (i.e. bus ) encounters any problem, whole network breaks down. This network topology is not suitable for networks with heavy traffic. And Security is very low because all the computers receive the sent signal from the source.
