A CMS (Content Management System) is a software application that enables users to create, manage, and modify digital content on a website without needing specialized technical knowledge. It provides an intuitive interface for users to publish and organize content, such as text, images, and multimedia. Popular examples of CMS platforms include WordPress, Joomla, and Drupal. These systems often include features like templates, plugins, and user management, allowing for customization and scalability while streamlining the web development process. CMSs are widely used for blogs, e-commerce sites, and corporate websites, making it easier for individuals and teams to maintain online presence efficiently.
