Question

hybrid, star, mesh (first diagram: connected nodes labeled mesh; second diagram: star - like node arrangement with empty box; third diagram: hybrid - like node arrangement with empty box)

Explanation:

Step1: Analyze the first pattern

The first diagram (mesh) has all nodes connected to each other. The second diagram has a central node with others connected only to it, which matches the "star" label (since star topology has a central hub).

Step2: Analyze the third pattern

The third diagram combines a star - like structure (central node with some connected) and a bus - like (the horizontal line with nodes) or other, fitting the "hybrid" label (as hybrid topologies combine multiple types).

Answer:

Second blank: star
Third blank: hybrid
