The Compare-Object cmdlet compares two sets of objects. One set of objects is the "reference set," and the other set is the "difference set."
The result of the comparison indicates whether a property value appeared only in the object from the reference set (indicated by the <= symbol), only in the object from the difference set (indicated by the => symbol) or, if the IncludeEqual parameter is specified, in both objects (indicated by the == symbol).
