In this lesson, we define what a Content Management System (CMS) is, exploring its role in creating, managing, and displaying digital content without advanced coding skills. We’ll look at major CMS platforms like WordPress and Joomla, discussing their core features and comparing their approaches to various projects (e.g., product catalogs, online communities, membership sites). You'll learn fundamental CMS concepts like the administrative backend and website frontend, and discover the key differences between static and dynamic web pages, setting the stage for deeper comparisons.
