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 is a type of network topology where all the devices are connected to a single central cable, called the bus or backbone. This backbone acts as a shared communication medium that transmits data to all connected devices.

• Each device is connected to the bus via a connector.
• Data sent from one device travels along the bus in both directions until it reaches the intended recipient.
• Terminators are placed at both ends of the bus to absorb signals and prevent reflection.

• Easy to implement and extend.
• Requires less cable than other topologies like star.

Disadvantages:

• If the main bus fails, the entire network goes down.
• Limited cable length and number of devices.
• Troubleshooting can be difficult.

Bus topology is commonly used in small networks or legacy systems.
