module

1. (architecture) A standard unit of measure used for determining the proportions of a building.

2. (programming) A section of a program; a subroutine or group of subroutines.Examples: "Class modules are similar to form modules except they do not have a visible interface (GUI)."; "When there is more than one protected module in memory, the rules for accessing the code and data sections of a given module treat all the other modules as if they were unprotected memory."

3. (algebra, ring theory) An abelian group equipped with the operation of multiplication by an element of a ring (or another of certain algebraic objects), representing a generalisation of the concept of vector space with scalar multiplication.Examples: "Modules over a ring are a generalization of abelian groups (which are modules over #92;textstyle#92;mathbb#123;Z#125;)."; "Approximately forty-five years ago K. Morita presented the first major results on equivalences and dualities between categories of modules over a pair of rings."; "One defines in like manner right K-modules and two-sided K-modules. If K is commutative, then every left K-module is automatically equipped with the structure of right and a two-sided K-module."

4. (fractal geometry, mathematics) A fractal element.

5. (music, computing) A file containing a music sequence that can be played in a tracker (also called mod or music module).

6. (hydraulics) A contrivance for regulating the supply of water from an irrigation channel.
