Bus topology
A bus topology is a type of network topology in which all devices
are connected to a single common cable called a backbone.
This cable acts as a common communication medium, allowing
all devices on the network to share and receive data. A problem with a communication cable can destroy the entire network. Even if a problem occurs in the system, it does not affect the entire network.
·
Advantages of Bus Topology.
·
It works
very efficiently well when there is a small networkIt is the easiest network
topology for connecting peripherals or device in a linear fashion.
·
The length
of cable required is less than a star topology.
·
It is easy
to connect or remove devices in this network without affecting any other
device.
·
Very
cost-effective as compared to another network topology i.e. mesh and star
·
It is easy
to understand topology.
·
Easy to
expand by joining the two cables together.
Disadvantages of Bus Topology
·
Bus topology
is not great for large networks.
·
Identification
of problems becomes difficult if the whole network goes down.
·
Troubleshooting
individual device issues is very hard.
·
Need
terminators are required at both ends of the main cable.
·
Additional
devices slow the network down.
·
If the main
cable is damaged, the whole network fails or splits into two.
·
Packet loss
is high.
