42% of the internet is powered by WordPress. It’s a free content management system that lets you create your own website or blog. It was created by Matt Mullenweg and released in 2003. Using a combination of PHP code and the MySQL database, WordPress web pages are dynamic in nature and different from the static HTML web pages.
WordPress comes in two versions – the self hosted WordPress.org and the fully hosted WordPress.com. Both are free. When some refers to WordPress, most of the time they are talking about WordPress.org.
