Which type of network topology is characterized by all nodes being connected to a single central hub?

The correct answer is the star topology, which is defined by all network nodes being connected to a central hub or switch. In a star topology, each device has a dedicated connection to the hub, making it easier to manage and troubleshoot the network. If one node fails, it does not impact the others, allowing network performance to remain stable.

This topology is particularly advantageous for organizations because the central hub can effectively manage communication between the nodes. Additionally, adding or removing devices is straightforward, requiring minimal disruption to the overall network.

In contrast, other topologies like mesh involve more complex interconnections between nodes, where each device is connected to one another, providing redundancy but requiring more cabling and complex management. The ring topology connects each node in a closed loop, where data travels in one direction, potentially impacting the entire network if a single connection fails. The bus topology features all devices connected to a single communication line, but it lacks the centralized management that the hub in a star topology provides, making it less reliable when dealing with problems.

Overall, the star topology’s structure allows for easier management and troubleshooting, making it an ideal choice for many modern networks.
