WordPress
Overview
WordPress is a free and open-source content management system (CMS) written in PHP and paired with a MySQL or MariaDB database. Features include a plugin architecture and a template system, referred to within WordPress as Themes.
History
WordPress was created by Matt Mullenweg and Mike Little in 2003 as a fork of b2/cafelog. The software is released under the GNU General Public License, which means it is not only free to download but free to edit, customize, and use.
Features
WordPress has a web template system using a template processor. Its architecture is a front controller, routing all requests for non-static URIs to a single PHP file which parses the URI and identifies the target page. This allows support for more human-readable permalinks.
Themes
WordPress users may install and switch among different themes. Themes allow users to change the look and functionality of a WordPress website without altering the core code or site content. Every WordPress website requires at least one theme to be present and every theme should be designed using WordPress standards with structured PHP, valid HTML and Cascading Style Sheets (CSS).
Plugins
WordPress' plugin architecture allows users to extend the features and functionality of a website or blog. As of June 2021, WordPress.org has 58,000+ plugins available, each of which offers custom functions and features enabling users to tailor their sites to their specific needs.
Mobiles
Native applications exist for WebOS, Android, iOS, Windows Phone, and BlackBerry. WordPress also features integrated link management; a search engine–friendly, clean permalink structure; the ability to assign multiple categories to posts; and support for tagging of posts and articles.
Security
WordPress' primary support website is WordPress.org. This support website hosts both WordPress Codex, the online manual for WordPress and a living repository for WordPress information and documentation, and WordPress Forums, an active online community of WordPress users.
