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

indirection

    Manipulating data via its address.  Indirection
   is a powerful and general programming technique.  It can be
   used for example to process data stored in a sequence of
   consecutive memory locations by maintaining a pointer to the
   current item and incrementing it to point to the next item.

   Indirection is supported at the machine language level by
   indirect addressing.  Many processor and operating system
   architectures use vectors which are also an instance of
   indirection, being locations which hold the address of a
   routine to handle a particular event.  The event handler can
   be changed simply by pointing the vector at a new piece of
   code.

   C includes operators "&" which returns the address of a
   variable and its inverse "*" which returns the variable at a
   given address.
