Editing Modular programming (section)

==Terminology==
The term [[Assembly (CLI)|assembly]] (as in [[.NET Framework|.NET languages]] like [[C Sharp (programming language)|C#]], [[F Sharp (programming language)|F#]] or [[Visual Basic .NET]]) or [[Package (package management system)|package]] (as in [[Dart (programming language)|Dart]], [[Go (programming language)|Go]] or [[Java (programming language)|Java]]) is sometimes used instead of '''module'''. In other implementations, these are distinct concepts; in [[Python (programming language)|Python]] a package is a collection of modules, while in [[Java 9]] the introduction of the [[Java Module System|new module concept]] (a collection of packages with enhanced access control) was implemented.

Furthermore, the term "package" has other uses in software (for example [[NuGet|.NET NuGet packages]]). A [[software component|component]] is a similar concept, but typically refers to a higher level; a component is a piece of a whole [[software system|system]], while a module is a piece of an individual program. The scale of the term "module" varies significantly between languages; in Python it is very small-scale and each file is a module, while in [[Java 9]] it is planned to be large-scale, where a module is a collection of packages, which are in turn collections of files.

Other terms for modules include '''unit''', used in [[Pascal (programming language)|Pascal]] dialects.
