What is WordPress? WordPress is an online, open source website creation tool written in PHP. But in non-geek speak, it’s probably the easiest and most powerful blogging and website content management system (or CMS) in existence today.

What’s a content management system (CMS)?
The definition of a CMS is an application (web-based), that provides capabilities for multiple users with different permission levels to manage (all or a section of) content, data or information of a website project, or intranet application.
Managing content refers to creating, editing, archiving, publishing, collaborating on, reporting, distributing website content, data and information.
