Which of the following network typologies incorporates a centralized point of control?

• A. Star
• B. Mesh
• C. Ring
• D. Tree

Answer: (A)

The star network topology is characterized by its centralized point of control, typically represented by a central hub or switch. In this arrangement, all nodes (devices) are connected directly to the central point, allowing for efficient data transmission and management. This configuration makes it easy to add or remove nodes without disrupting the entire network. In a star topology, if one connection fails, it does not affect the rest of the network, as each device communicates independently with the central hub. This centralization simplifies troubleshooting, as issues can often be identified by checking the hub or the specific link where a problem exists. The other topologies—mesh, ring, and tree—either lack this centralized control or distribute connectivity in a way that complicates management. For example, a mesh topology offers complete interconnectivity among all nodes, making it decentralized and resilient but complex to manage. Similarly, a ring topology connects nodes in a circular fashion, and communication passes through each device, which creates difficulties if one node fails. In a tree topology, while there is a hierarchical structure, it does not have the same centralized control as a star configuration since it combines characteristics of star and bus topologies. Overall, the star topology's effectiveness is largely due to its centralized control mechanism,
