What is WordPress?
is a free and open source blogging tool and a content management system (CMS) based on PHP and MySQL, which runs on a web hosting service. Features include a plug-in architecture and a template system.
WordPress is used by more than 18.9% of the top 10 million websites as of August 2013 and is the most popular blogging system in use on the Web, at more than 60 million websites.
It was first released on May 27, 2003, by its founders, Matt Mullenweg
and Mike Little
, as a fork of b2/cafelog. Since December 2013 until February 19, 2014, version 3.8 had been downloaded more than 20 million times.
WordPress users may install and switch between themes. Themes allow users to change the look and functionality of a website or installation without altering the information content or structure of the site.
One very popular feature is its plugin
architecture which allows users and developers to extend its abilities beyond the core installation. WordPress has a database of over 30,000 plugins (February 2014), each of which offers custom functions and features enabling users to tailor their sites to their specific needs.
