A content management system (CMS) is software that facilitates the creation, management, and modification of digital content without requiring technical knowledge. It provides a user-friendly interface for users to easily update websites or blogs, allowing for collaborative content creation among multiple authors. Popular CMS platforms, such as WordPress and Joomla, often include templates and plugins to enhance functionality. By simplifying content management, a CMS empowers organizations to maintain an active online presence and engage their audience effectively.
