Difficulty: Easy
Correct Answer: Star network
Explanation:
Introduction / Context:
Network topology describes how nodes are arranged and interconnected. A centralized pattern, in which many devices connect to a single focal point, is especially common in modern Ethernet LANs and wireless infrastructures, enabling straightforward management and fault isolation.
Given Data / Assumptions:
Concept / Approach:
In a star topology, each node has a point-to-point link to a central hub, switch, or controller. That central device mediates communication between nodes. By contrast, a bus uses a shared medium; a ring forms a closed loop where frames circulate; a mesh has multiple interconnections among nodes without a single point of concentration.
Step-by-Step Solution:
Match the description (one center with satellites) to known topologies.Recognize the defining feature of a star: centralized connectivity at one node.Exclude bus/ring/mesh because they do not have a single central node by definition.Select “Star network.”
Verification / Alternative check:
Modern Ethernet with switches is a physical star (often logical star as well). Topology diagrams consistently depict a central switch with spokes to each host.
Why Other Options Are Wrong:
Bus: uses a shared backbone; no single central node.Ring: nodes arranged in a loop; no central node.All of the above: only one topology matches the description.
