What are the types of network topology?

The types of network topology encompass the various configurations in which network devices are arranged. The correct answer identifies three common types of topology: Star, Bus, and Mesh.

Star topology involves all nodes being connected to a central hub or switch. This central point facilitates communication between the nodes, making it easy to manage and troubleshoot the network. If one connection fails, it does not affect the rest of the network, making this topology resilient.

Bus topology connects all devices along a singular central cable (the bus). Data sent from a device travels along this cable, and all devices check the data and process it if the address matches their own. While this can be simple and cost-effective, the entire network can be affected by a failure in the bus.

Mesh topology enhances reliability by connecting each node to one another, creating multiple paths for data. This means if one connection fails, data can still find another route to its destination. This redundancy is beneficial for critical networks where uptime is a priority.

In summary, B accurately reflects three key types of network topology widely employed in computer networking, showcasing their respective advantages and operational mechanisms. The other choices either mix topologies inaccurately or include uncommon types not traditionally classified in basic network architecture.
