The Free On-line Dictionary of Computing (30 December 2018):

pointer
reference

   1.  An address, from the point of view of a
   programming language.  A pointer may be typed, with its type
   indicating the type of data to which it points.

   The terms "pointer" and "reference" are generally
   interchangeable although particular programming languages often
   differentiate these two in subtle ways.  For example, Perl
   always calls them references, never pointers.  Conversely, in
   C, "pointer" is used, although "a reference" is often used to
   denote the concept that a pointer implements.

   Anthony Hoare once said:

   Pointers are like jumps, leading wildly from one part of the
   data structure to another.  Their introduction into high-level
   languages has been a step backward from which we may never
   recover.

   [C.A.R.Hoare "Hints on Programming Language Design", 1973,
   Prentice-Hall collection of essays and papers by Tony Hoare].

   2.  (Or "mouse pointer") An icon, usually
   a small arrow, that moves on the screen in response to
   movement of a pointing device, typically a mouse.  The
   pointer shows the user which object on the screen will be
   selected etc. when a mouse button is clicked.
