CMS is an abbreviation for the term Content Management System. A CMS is a web application that helps website owners add, edit and manage pages on their website. It can additionally be known as the website Dashboard or backend, where updates are made and content is added or deleted. The major advantage of a CMS is that content doesn’t need to be coded using the web markup language HTML and then uploaded. Instead, users log in to the CMS and use a more user-friendly interface to add and edit the content that appears immediately on the website once updated.
