Plugin

A plugin is a piece of software that adds extra functionality to an existing program, a component that allows for customization and extension of its functions.

Plugins are designed to be easily installed and integrated into the main software, giving users the ability to adapt the program to their specific needs without having to modify the source code.

In the context of web design and development, plugins are often used with content management systems such as WordPress to add features such as contact forms, image galleries, SEO tools, e-commerce functionality, and more.

Some CMSs, such as Drupal or PrestaShop, use the term “modules” instead of “plugins,” but the concept is the same: they are add-ons that extend the functionality of the main system and allow users to create websites that meet their specific needs.
