Network Topology Closed Loop Identification

The question asks to identify the network topology where connected devices form a closed loop. This means each component is connected to exactly two other components, forming a single continuous pathway for signals.

Topology Analysis for Closed Loop Structure

• Ring Topology: In a ring topology, each device is connected to exactly two other devices, one on either side. This arrangement creates a circular path, or a closed loop, through which data packets travel. Data typically moves in one direction (e.g., clockwise or counter-clockwise) around the ring.
• Tree Topology: This is a hybrid topology that combines characteristics of bus and star topologies. It has a hierarchical structure with a root node and branches, but it does not form a single closed loop.
• Bus Topology: All devices are connected to a single central cable, known as the bus or backbone. This setup is linear, not a closed loop.
• Star Topology: All devices are connected to a central hub or switch. If the central device fails, the entire network goes down. This topology resembles spokes on a wheel and does not form a closed loop.

Based on the definition, the ring topology is the network structure where connected components form a closed loop.
