The CMS comes with news, sections, pages, default, login and configuration components installed in the back end.
The front end uses modules to present units of information, whether associated with a component or not, and pages act as their containers.
Assuming the software is used in a publishing environment, content would be organised into news articles and sections. There would also be a page for every section and every article entered into the system.
Creating a section should not require configuring a new page and specifying its modules. Instead, the section page should be understood as a container for all sections.
The same applies to news: the article page would encompass all articles.
Other pages will probably also be needed to display static content, modules from other components, or a mixture of content, as on the home page, index, which includes modules from several components.
