BUS TOPOLOGY

Bus Topology

Bus Topology• A bus topology is a type of

network setup where each computer and network device are connected to a single cable or backbone.

• A bus topology is multipoint.

How Bus Topology Works

• The bus is the data link in a bus network. • The bus can only transmit data in one

direction, and if any network segment is severed, all network transmission ceases.

• A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic.

• The traffic generated by each station has equal transmission priority.

Bus Topology

Advantages of Bus Topology

•Easy to connect a computer or peripheral to a linear bus•Requires less cable length than a star topology•It works well for small networks.

Disadvantages of Bus Topology

• Entire network shuts down if there is a break in the main cable

• Terminators are required at both ends of the backbone cable

• Difficult to identify the problem if the entire network shuts down

• Not meant to be used as a stand-alone solution in a large building

• It is slow when more devices are added into the network

• If a main cable is damaged then network will fail or be split into two networks

Applications of Bus Topology

• Used for broadcasting the message.• Most Computer Motherboards.• Used in LAN.
