What is a module?

A module is a component that can be added to a software program to add new functionalities, without altering the basic structure of the software.

Characteristics of modules

Modules can:

• add additional functionalities, or modify existing functionalities
• be developed by the creators of the original software, or by third-party developers
• be installed or uninstalled independently of other modules
• require updates that are independent of the base software
• be referred to as "addons", "plugins" or "extensions"
