In a network where every node is connected to every other node, this is known as?

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

Answer: (A)

Direct interconnection of every node to every other node describes a mesh topology. In a mesh, each device has a direct link to all others, which provides the highest redundancy and fault tolerance because there are dedicated paths for data between any two nodes. If one link or path fails, traffic can take an alternate route without losing connectivity. This level of interconnectivity is what makes mesh the correct fit for the description. By contrast, a star relies on a central hub, a ring connects in a circular loop, and a bus uses a single shared backbone, none of which guarantee direct, multiple inter-node connections.
