What is WordPress?
WordPress is the simplest and most powerful blogging and website content management system (CMS) in existence today. It gives you the freedom to create any type of website or blog in minutes.
How does It work?
WordPress powers both the backend of the website (the interface where an admin logs in to make changes or add or publish new content) and the frontend (the visible part of the website that your visitors see on the web).
In other words, the WordPress frontend is completely controlled by the themes. A WordPress theme decides the looks and functionality of your blog or website.
While WordPress mostly works on the backend where admin logs in to write or publish new content.
What is a WordPress Website or Blog?
A WordPress website or blog is any website that uses WordPress as its CMS (content management system). My website is also a WordPress website as I’m using WordPress as my CMS.
I hope you got some idea about WordPress and how it works.
