Yes, a module is Lua source code in a page in the Module namespace which provides functions that can be invoked from templates (and also from articles, though it is usually best to have a template as an intermediary). Modules can also require other modules and use functions provided by these other modules.

It is possible to require one of the global modules from dev.wikia.com with. The modules I made for the infoboxes use some of these modules.
