Consider a packet-switching network of N nodes, connected by the following topologies:

Star: One central node with no attached station; all other nodes attach to the central node

Loop: Each node connects to two other nodes to form a closed loop

Fully connected: Each node is directly connected to all other nodes

For each case, diagram the topology and give the average number of hops between stations. Create a PowerPoint file with 3 slides to display each topology and the average number of hops.

I need the diagrams of these topologies. I have the rest of the information.
