From The Free On-line Dictionary of Computing (05 January 2017) [foldoc]:
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.
