•Modules
are more lightweight and flexible extensions used for page rendering.
•Sometimes
modules are linked to components such as the “latest news” module which links to the com_content and displays
links to the newest content items.
•These
modules are mostly known as the “boxes” that are arranged around a component, for example: the login module. The
footer is a module.
•Modules
are assigned per menu item. So, you can decide to show or hide the logon module depending on which component (menu
item) is used.
•Modules
do not need to be linked to components, as a matter of fact they don't even need to be linked to anything and can be
just static HTML or text.
•For example:
mod_banners, mod_mainmenu
–Admin head menu > “Extensions” > “Module Manager”
