The back-end, or the “server-side”, is basically how the site works, updates and changes. This refers to everything the user can’t see in the browser, like databases and servers. Usually people who work on the back-end are called programmers or developers. Back-end developers are mostly worried about things like security, structure and content management. They usually know and can use languages like HTML and CSS, but that’s definitely not their focus. Back-end developers, or at least back-end development, is required to create a dynamic site. A dynamic site is a site that’s constantly changing and updated in real-time.
