13. What is a Joomla module?

A module, for the most part, is a program to
create content that surrounds your “main
content” section. These are mainly displayed in
the different module positions: top, left, right,
etc. Joomla modules usually go hand-in-hand
to display certain information from other
installed components. Ex: display latest forum
post made on your forum component, display
random images from your image gallery
component, display latest news, most popular
articles, so on and so on. Even the menus are
modules. Note: You can display modules in
“main content”, but that’s another how-to.
