In section, there is one or more category. The articles are entered into one of the categories. Category manages in the Category Manager page. You can access this page through Content > Category Manager. In this page, you can make, modify, copy, and delete category.

If we want to delete a category, such as in section, Joomla! will examine whether there is an article in category or not. If there is, the category will be not deleted.
