Joomla Extensions
Joomla extensions extend the functionality of your websites. There are five types of extensions, each tasked with a specific function:
- Components: they are the largest and most complex extensions. Most of the components are divided into two: a site and an administrator. Each time a Joomla page loads, a component receives the call to produce the main body of the page. The components generate most of the page, directed by a menu item.
- Plugins: are advanced extensions; in essence, they are the event handlers. When running any Joomla extension, module, or component, an event might be triggered. In that case, the plugins that are registered to handle that event run.
- Templates: Describe the main design of a Joomla website. While the CMS manages the content of the website, templates determine the style or appearance.
- Modules: generate the pages in Joomla. They are linked to components to display new content or images. They have the appearance of boxes, such as the search or login module.
- Languages: These are a very simple extension that is either used as a part of the kernel or as an extension. Font language and information can also be used for PDF or PSD in conversions.
