Bus Topology:-

            Bus topology is a network type in which every computer and network device is connected to a single cable. When it has exactly two endpoints, then it is called Linear Bus topology.

Features of Bus Topology:

• The data signal is available to all computers connected to the bus.
• It carries the address of the destination computer.
• Bus topology is good for connecting 15-20 computers.
• Each computer on the network checks the destination address as the data signal travels through the bus.

Advantage of Bus Topology:-

• Bus topology cost is very low
• Required less cable length compared to other networks such as start topology.
• Easy to connected computer peripheral to a linear bus.
• It is easy to extend a bus.
• It works well for small networks.

Disadvantages of Bus Topology:-

• If there is a break in the main cable, the entire network will be shut down.
• If network gets heavy traffic, a node’s performance of the network falls.
• The length of cable is limited.
• It is difficult to troubleshoot a bus.
