What is WordPress – Simple Definition
WordPress is free, open-source software that allows anyone to create a website without coding knowledge. It is the world's most popular website platform, powering over 43% of all websites on the internet in 2026 — from personal blogs to major news sites like BBC America and TechCrunch to the White House website.
WordPress provides a user-friendly dashboard where you can write articles, add pages, upload images, install themes (design templates), and add plugins (feature extensions) — all without touching a single line of code.
WordPress.com vs WordPress.org – What is the Difference?

| Custom Domain | Yes, fully | Paid plans only |
| Plugins | 60,000+ plugins | Limited selection |
| Monetization | Full freedom | Restricted on free plan |

Recommendation: Always use WordPress.org (self-hosted) for serious websites, blogs, and businesses. WordPress.com is fine for casual personal use only.

WordPress stores your website content in a database and combines it with theme files to generate web pages dynamically. When a visitor comes to your site, WordPress retrieves the content from the database, applies your chosen theme design, and displays the page in the visitor's browser.
You manage everything through the WordPress dashboard — a web-based interface you access by going to yoursite.com/wp-admin and logging in with your username and password.
Key WordPress Concepts
Themes
Themes control how your website looks. Thousands of free themes are available in the WordPress theme directory. Popular free themes: Astra, GeneratePress, Kadence. Install a theme: Dashboard → Appearance → Themes → Add New.
Plugins
Plugins add functionality to WordPress. Need a contact form? Install a contact form plugin. Need SEO tools? Install Yoast SEO. There are 60,000+ free plugins. Install: Dashboard → Plugins → Add New.
Posts vs Pages
Posts are dated blog entries (articles). Pages are static content like About, Contact, or Services. Use posts for your blog content and pages for permanent sections of your site.
The Block Editor (Gutenberg)
WordPress uses a block-based editor. Each piece of content (paragraph, image, heading, video) is a separate block you can move, resize, and style independently. Easy to use without any design experience.
