is a self-contained component of a system
, which has a well-defined interface
to the other components; something is modular
if it includes or uses modules which can be interchanged as units without disassembly of the module. Design, manufacture, repair, etc. of the modules may be complex, but this is not relevant; once the module exists, it can easily be connected to or disconnected from the system.
Module may also refer to:
In abstract algebra, a module is a generalisation of a vector space.
