A content management system (CMS) is software that enables users to create, manage, and modify content on a website without the need for specific technical knowledge. A CMS makes it easy for users to design and build a website without having to create the code themselves. They are capable of handling all the basic infrastructure needs for a website, allowing users to focus on the front end. WordPress is the world’s most popular CMS, but other common ones include Drupal, Moodle, Phpbb, Joomla and more.
