Question

Explain Bus Topology with diagram.

Hint:

Bus topology connects all devices via a single backbone cable; it's simple but has limitations in fault tolerance.

Answer 1

Bus Topology: A network configuration where all devices connect to a single, central cable (the bus or backbone). This backbone serves as the shared communication pathway, broadcasting data to all connected nodes.

• Devices connect to the bus using connectors.
• Data travels bidirectionally along the bus until it reaches its destination.
• Terminators at each end of the bus absorb signals, preventing reflection.

• Simple to set up and expand.
• More economical in terms of cabling compared to topologies like star.

Disadvantages:

• A single bus failure incapacitates the entire network.
• Constraints exist on cable length and the quantity of connected devices.
• Diagnosing issues can be challenging.

Bus topology is prevalent in smaller networks and older systems.
