Differences between [[Class_(computer_science)|classes]] and modules are the following:

* Classes can be instantiated to create [[Object_(computer_science)|objects]],

* Classes can [[Inheritance_(object-oriented_programming)|inherit]] behavior and data from another class,

* [[Polymorphism_(computer_science)|Polymorphism]] allows relationships between class instances to change at run-time, while relations between modules are static.

Similarities between [[Class_(computer_science)|classes]] and modules are the following:

* Both can be used to hide abstraction from public view.

* Both can form a hierachie of modules/classs.

Languages that explicitly support the module concept include [[Ada programming language|Ada]], [[D_programming_language|D]], [[F programming language|F]], [[Fortran|Fortran]], [[Haskell_programming_language|Haskell]], [[ML_programming_language|ML]], [[Modula-2]], and [[Python_programming_language|Python]].

== Module Interconnection Languages (MILs) ==

'''Module Interconnection Languages (MILs)''' provide formal grammar constructs for deciding the various module interconnection specifications required to assemble a complete software system. MILs enable the separation between programming-in-the-small and programming-in-the-large. Coding a module represents programming in the small, while assembling a system with the help of a MIL represents programming in the large. An example of MIL is MIL-75.
