What is the purpose of an add-on in software?

An add-on in software is designed to enhance or extend the capabilities of existing software applications. This can involve adding new features, improving functionality, or integrating with other services. For example, a web browser might use add-ons to enable additional features like ad-blocking, language translation, or social media integration. These enhancements allow users to customize and optimize their software experience according to their specific needs and preferences.

The other options do not accurately describe add-ons: hardware enhancements refer more to physical components that improve device performance, while a separate operating system component does not fit the category of software extensions. Lastly, a backup utility specifically addresses data recovery rather than enhancing the functionality of other software.
