  <p>A reference is an object containing information which refers to data stored elsewhere, as opposed to containing the data itself. 
  A reference data type is a data type that specifies how a reference is represented and stored in memory,
   as well as the operations that can be performed on reference values. 
  The most common example of a reference data type is a pointer.
