Which type of software provides additional functionality to the operating system?

Utility software is specifically designed to perform maintenance tasks that help manage and tune computer hardware, operating system, or application software by performing a specific task. This type of software enhances the performance of the operating system by providing additional features that assist with system management, security, and efficiency. For instance, utility software can include antivirus programs, disk management tools, file management utilities, and backup software, all of which add value to the overall operation of a system.

In contrast, application software refers to programs that help users perform specific tasks, such as word processing or spreadsheet creation, rather than enhancing the operating system directly. System software, while also crucial, mainly refers to the operating system itself and the software that supports it, rather than providing additional functions. Database software is targeted for creating and managing databases, and while it integrates closely with the operating system, it does not specifically serve the broader functionalities that utility software provides to maintain and enhance the operating system's capabilities.
