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

activation record
data frame
stack frame

    (Or "data frame", "stack frame") A data structure
   containing the variables belonging to one particular scope
   (e.g. a procedure body), as well as links to other activation
   records.

   Activation records are usually created (on the stack) on
   entry to a block and destroyed on exit.  If a procedure or
   function may be returned as a result, stored in a variable and
   used in an outer scope then its activation record must be
   stored in a heap so that its variables still exist when it
   is used.  Variables in the current scope are accessed via
   the frame pointer which points to the current activation
   record.  Variables in an outer scope are accessed by following
   chains of links between activation records.  There are two
   kinds of link - the static link and the dynamic link.
