To understand what WordPress is, you need to understand what content management systems (CMS) are. A CMS is a system which manages online content. It is a software that helps users create, edit, organize, and publish digital content. While a website builder usually provides ready-made building blocks from which you can create websites, a CMS offers more freedom, flexibility, and extensions in the form of plugins and themes. The backend interface is where your content is organized and managed, while the CMS frontend displays the published website.
The CMS comparison guide indicates that WordPress is the most successful CMS worldwide. About 40 percent of all websites worldwide are made with WordPress, while 60 percent of all CMS websites use it. WordPress is a free open-source CMS which private users, bloggers, businesses, and artists use to create and manage WordPress sites. Another great advantage is that it does not require any programming skills. However, online storage in the form of MySQL or MariaDB databases are necessary to save content, user accounts, themes, and plugins. FTP access and a domain are also required, as well as HTTPS and the server-side programming language PHP. However, many hosting providers will offer WordPress packages that fulfill all these requirements.
