This text will start by defining the Joomla Module, then it will detail three default Joomla modules.
Joomla Module is a lightweight and flexible Extension used for page rendering. In Joomla, Module = Widget = A block of code that can be placed in a template position.
You usually place a module into a Position in the Template. The Position is a placeholder in the template where you can place a module. The Template is the visual presentation of a Joomla site.
Modules sometimes got mixed with Plugins, Plugins are also small extensions that extend the functionality of Joomla; Plugins may or may not contain MarkUp to be rendered on the page.
The module usually contains two parts:
Frontend: The part that is rendered on the page.
Backend Code: The part of the module code that gets executed in the backend, and resulted in the rendering of the Frontend.
Backend Configuration: In the Admin Panel, you can configure the module, and the configuration is saved in the database. Then these configurations will be used the next time the module got executed.
The Three chosen modules are:
Breadcrumbs: This module displays a list of links to the current page; and the parent pages.
Login: This module displays a login form and a logout link.
Statistics: This module displays some statistics about the site.
Breadcrumbs. It is a module that displays a list of links to the current page, and the parent pages, till the root page.
This module is useful for users to locate themselves on the website at any time.
The BreadCrumbs module is a default module in Joomla, and it is enabled by default. But, you can disable or hide it on some pages using the Backend Configuration Form of the module.
The form has a few fields like title, name, show title, show home, show last, separator, position, access and Ordering.
Once any of these fields are changed, the module will be re-rendered on the page.

Login. It is a module that displays a login form and a logout link.
If the user is not logged in, the login form will be displayed, and if the user is logged in, the logout link will be displayed.
The authentication state will be shared between the Frontend and the Backend and will last until the user logs out or the session expires.
