WordPress (WordPress.org) is an open source Content Management System. It is powered by plugins and themes for building websites. We can build a blog, profile, e-commerce and other sites.
WordPress was released on May 27, 2003, by its founders, Matt Mullenweg, and Mike Little, as a fork of b2/cafelog. The software was released under GPLv2 (or later) license.
To function, WordPress has to be installed on a webserver like WAMP, XAMPP, which later helped to install wordpress in our computers to design the website. We need a hosting company to host the website.
