Question: I do not understand this question? A graph G = (V,E) is bipartite if its vertices can be partitioned into two subsets V =A ?

I do not understand this question? "A graph G = (V,E) is bipartite if its vertices can be partitioned into two subsets V =A ? B such that all edges connect only vertices between the two sets (no two edges in the same set are connected)." what's meaning of that?
