Network topology explained || bus topology with example || how bus topology works

Network topology is the layout, pattern, or organizational hierarchy of the interconnection of network hosts.
Network Topology=structure of Network.

Bus Topology: 

 

all nodes are connected to a common medium along this medium. This was the layout used in the original Ethernet,

A bus network is a network topology in which nodes are directly connected to a common half-duplex link called a bus.
In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority

Advantages:

1.     Very easy to connect a computer or peripheral to a linear bus.
2.     Requires less cable length than a star network resulting in lower costs.
3.     The linear architecture is very simple and reliable.
4.     It works well for small networks.
5.     It is easy to extend by joining cable with connector or repeater.

Disadvantages

1. Collisions occur in the network resulting in packet loss.
2. Bandwidth is shared among nodes; Performance may degrade with many nodes on the network.
3. It is difficult to isolate faults in the network.
4. The entire network shuts down or is divided into two separate networks if there is a break in the main cable.
