What type of network topology features a central node connecting to every device on the network?

The star network topology is characterized by its structure, where a central node, often referred to as a hub or switch, connects directly to all other devices in the network. This configuration allows each device to communicate with others through the central node, facilitating efficient data transmission and management.

One of the primary benefits of a star topology is its simplicity and ease of troubleshooting. If one of the peripheral devices fails or a cable disconnects, it does not impact the entire network; only the specific device affected will be taken offline. Additionally, adding or removing devices can be done with minimal disruption, further enhancing flexibility in network management.

This centralized structure also provides advantages in performance. Since the central node controls data traffic, it can manage connections more effectively than other topologies, resulting in improved network efficiency.

In contrast, other topologies such as mesh, bus, and ring have different structures and characteristics, which do not rely on a central node, leading to distinct operational and performance implications. For instance, in a mesh network, every device connects to one another, allowing for higher redundancy but at the cost of increased complexity.
