WordPress Overview
What Exactly Is WordPress?
WordPress is an open-source content management system (CMS) written in PHP and powered by a MySQL or MariaDB database. In simple terms, it’s a platform that allows users to create and manage websites without needing to write code from scratch.
Instead of manually building pages using HTML, CSS, and JavaScript, WordPress provides:
- A user-friendly dashboard
- Visual editors
- Themes for design
- Plugins for functionality
This makes website creation accessible to beginners while still offering advanced customization for developers.
How WordPress Works Behind the Scenes
At its core, WordPress separates content, design, and functionality:
- Content: Posts, pages, media, and text you add
- Design: Controlled by themes
- Functionality: Added via plugins
When a visitor loads your website, WordPress:
- Retrieves content from the database
- Applies the active theme’s design
- Executes plugins for added features
- Displays the final page to the user
This modular structure is one of the reasons WordPress is so popular — it allows endless customization without breaking the core system.
Why WordPress Is Open Source
WordPress is licensed under the GNU General Public License (GPL), meaning:
- It’s free to use
- You can modify it
- You can redistribute it
Being open source has fueled massive community growth. Developers worldwide contribute to WordPress core updates, security patches, themes, and plugins. This collaborative model ensures continuous improvement and long-term sustainability.
