WordPress runs on a web server, crucial for developing sites, plugins, and themes. Web servers serve web pages and utilize a tech stack, typically LAMP (Linux, Apache, MySQL, PHP) or LEMP (Linux, Nginx, MySQL, PHP). Apache software serves requests while Nginx is a faster alternative. Configurations allow serving multiple sites (virtual hosts for Apache, server blocks for Nginx). WordPress request flow involves the browser requesting data, PHP executing code (often querying MySQL), and returning HTML to the browser for rendering. Understanding this is vital for effective WordPress development.
