Modules are pieces of code that can be loaded and unloaded into the kernel upon demand. They extend the functionality of the kernel without the need to reboot the system. For example, one type of module is the device driver, which allows the kernel to access hardware connected to the system.
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.urthermore, the term package has other uses in software. A component is a similar concept, but typically refers to a higher level; a component is a piece of a whole system, while a module is a piece of an individual program.
