What is a WordPress plugin?

Give a clear definition of what is a plugin for WordPress is not easy, especially for non-experts. We can start by saying that WordPress Plugins are an added component to WordPress and are used to modify or extend the functionality.
A plugin is frequently called module in other similar applications, but the definition remains specifically the same.

Why should you use WordPress plugin?
The purpose of a plugin is to allow users to perform operations in a manner different from that provided by WordPress or add new tasks to those already pre-defined.
To make an immediate plugin example we can say that one of these is the one that adds to WordPress user roles, in addition to those pre-established, improving in this way the functionality. A second type of plugins are the ones who run the slideshow, or at least everything that is not natively provided by WordPress.

In the admin section of WordPress panel you can activate or deactivate your plugins. If activated, WordPress includes its code in its entire execution flow, allowing the plugin to operate in both the frontend and in backend of the site. Otherwise, when a plugin is disabled, WordPress removes it from its execution flow and behaves as if the plugin does not exist, and the plug-in code is no longer executed.
It must be said that a plugin can make changes to WordPress (overwriting parts if its code), that’s why if you have a bug problem, even the plugin will have a problem and consequently WORDPRESS. For this reason, to solve problems and vulnerabilities, when it happens we must first disable the plugin in order to locate the source of the problem (a fault, a flaw, or other …).
Another feature is that the plugin can be: free, downloadable by  the official repository of WordPress, or premium, similarly easy in usage but hosted by developer’s website.
We can safely say that those in charge can be updated more frequently and in detail from the developer, and are definitely compatible with the latest WordPress updates.

Plugins Update and Website Safety


Updating a plugin to the latest version is an essential requirement to better manage WordPress. A plugin that is never updated will cause problems with upgrades of WordPress versions and represent itself a potential safety issue. Moreover if a plugin is disabled but its files are not deleted, they can be used for remote attacks. The problem of security, and usability, is a major issue for WordPress plugin. In the choice of your favorite plugins these aspects must be considered as fundamental: choose and install well-coded and frequently updated plugins and take care of your WordPress website! 🙂
