Fully connected graph

In graph theory it known as a complete graph. A fully connected network doesn't need to use switching nor broadcasting. However, its major disadvantage is that the number of connections grows quadratically with the number of nodes, per the formula. c=n (n-1)/2, and so it is extremely impractical for large networks.

If the graph is fully connected it requires storing 3,000,000 values.A graph is said to be connected if every pair of vertices in the graph is connected. This means that there is a path between every pair of vertices. An undirected graph that is not connected is called disconnected .
