Which type of network topology involves a central hub with all nodes connected to it?

The correct answer identifies a star topology, which features a central hub or switch to which all other nodes are directly connected. In this configuration, each node communicates with the hub, which manages data transmission between the nodes.

This design facilitates easy management and troubleshooting; since the failure of a single node does not affect the entire network, the remaining nodes continue to operate normally. Furthermore, if any particular node fails, it can be replaced or repaired without disrupting the network’s overall function. The centralized structure also simplifies the process of adding or removing devices.

In contrast, other topologies like bus involve a single central cable with all nodes connected to it, leading to potential network failure if the main cable needs repair. Mesh topology, while robust and offering multiple pathways for data, consists of nodes interconnected in a web-like fashion, increasing complexity and cost. Ring topology connects nodes in a circular manner, where data travels in one direction, making it vulnerable to complete network failure if a single connection breaks.

Understanding these differences emphasizes the advantages of a star topology for scalability, reliability, and ease of maintenance in network implementations.
