PHP is a scripting language widely used for web development, with code processed on a web server through a PHP interpreter, implemented as a module, daemon, or CGI executable. Nginx lacks the default ability to handle dynamic web pages with PHP and requires specific additional plugins for this purpose. One such plugin is FPM (FastCGI Process Manager), an alternative PHP FastCGI implementation offering additional features, particularly advantageous for high-traffic sites. FPM stands out as the preferred method for PHP page processing with Nginx, surpassing traditional CGI-based methods in terms of speed.

A piezo buzzer is not like a regular speaker that you might think of. It uses a material that actually changes shape when you apply electricity to it which in turn creates noise. The faster you bend the material, the higher the pitch of the noise that is produced.

A piezo buzzer is a small device that converts electrical signals into sound waves. Unlike traditional speakers, piezo buzzers operate on the piezoelectric effect. When a voltage is applied, the buzzer's piezoelectric crystal deforms, producing sound waves. This simplicity makes piezo buzzers cost-effective, lightweight, and ideal for applications where the space is limited.
