A content management system (CMS) allows non-technical users to manage and modify website content without needing a programmer. It has two parts: a content management application that lets users create and remove content, and a content delivery application that updates the website. A CMS is well-suited for small businesses as it helps keep websites up to date more easily. However, it may not be suitable for international companies. Overall, a CMS makes both maintaining and creating a website simpler.
