The Bus Topology is also known linear bus. It consists of several computers which are attached to a common cable called the trunk line.
Bus Network
In the bus topology, data on the network is sent to all the computers on the network. However, the data is accepted only by the computer that has the address matching the address in the signal. Only one computer at a time can send messages. The bus topology is a passive topology in which the computers on the bus are not responsible for moving data. In this, failure of one computer does not affect the performance of the network. The performance on a bus network can be affected by the following factors:
- Number of computers on the network
- Hardware capabilities of computers on the network
- Frequency of data transmission
- Types of cable used on the network
- Distance between computers on the network
Note: Every computer on the network has an address. Data that is sent from a computer that contains the address of the computer to which it is sent.
