A CMS, short for Content Management System, is a software application that allows users to create, manage, and modify content on a website without the need for technical knowledge. It acts as a single place to store content and enables multiple contributors to create, edit, organize, and publish content. A CMS typically has two major components: a content management application (CMA), which is the front-end user interface that allows a user, even with limited expertise, to add, modify, and remove content from a website without the intervention of a webmaster; and a content delivery application (CDA), which compiles the content and updates the website. There are two types of CMS installation: on-premises and cloud-based. On-premises installation means that the CMS software can be installed on the server, while cloud-based CMS is hosted on the vendor environment. CMS features include index and retrieval, format management, revision control, and management. CMSs can be used to create essentially any type of website, including static websites, blogs, eCommerce stores, forums, social networks, online courses, membership sites, portfolios, and more. Popular CMS platforms include WordPress, Joomla, Drupal, Magento, Squarespace, Wix, and TYPO3.
