what is plugin in wordpress | website design in nepal

A plugin is a piece of software that enhances the functionality of a computer program or application that already exists. Web browsers frequently employ plugins to add functionality like video playback, PDF viewing, or ad-blocking. They can also be incorporated into several kinds of software, including video, audio, and photo editors.

Plugins are designed to be easily installed and integrated into an existing application without the need for extensive programming or development. Many popular software applications have plugin architectures that allow third-party developers to create plugins that extend the functionality of the core application.

Plugins can be either open source or proprietary, and they may be available for free or sold as commercial products. They are typically distributed as standalone files that can be downloaded and installed manually, or through an automated installation process.
