What is "wordpress"

Wordpress is a web-based content management system (CMS) application, written in php with database mysql, focused mainly on the creation of websites and blogs. This tag includes questions about development and modification of themes and plugins, and extension of your source code.

It’s the same software used in the blogging service Wordpress.with and in premium service Wordpress.com VIP, but in the Wordpress.org the main difference is access to source code, installation in virtually all companies of hosting and be able to add components (plugins and themes) freely to the site.
