From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  closure
       
          1.  In a {reduction system}, a closure is a data
          structure that holds an expression and an environment of
          variable bindings in which that expression is to be evaluated.
          The variables may be local or global.  Closures are used to
          represent unevaluated expressions when implementing
          {functional programming languages} with {lazy evaluation}.  In
          a real implementation, both expression and environment are
          represented by pointers.
       
          A {suspension} is a closure which includes a flag to say
          whether or not it has been evaluated.  The term "{thunk}" has
          come to be synonymous with "closure" but originated outside
          {functional programming}.
       
          2.  In {domain theory}, given a {partially ordered
          set}, D and a subset, X of D, the upward closure of X in D is
          the union over all x in X of the sets of all d in D such that
          x <= d.  Thus the upward closure of X in D contains the
          elements of X and any greater element of D.  A set is "upward
          closed" if it is the same as its upward closure, i.e. any d
          greater than an element is also an element.  The downward
          closure (or "left closure") is similar but with d <= x.  A
          downward closed set is one for which any d less than an
          element is also an element.
       
          ("<=" is written in {LaTeX} as {\subseteq} and the upward
          closure of X in D is written \uparrow_\{D} X).
