A content management system (CMS) is a software application or set of tools that is used to create, manage, and publish digital content. A CMS provides a user-friendly interface that allows non-technical users to easily create, edit, and publish content, such as blog posts, articles, and product pages. It also provides a way to organize and manage the content, including assigning roles and permissions to different users, and scheduling content to be published at a later time. CMSs are commonly used by businesses, organizations, and individuals to create and maintain websites and other digital platforms. Some popular examples of CMSs include WordPress, Drupal, and Joomla.
