What role does utility software serve in a computer system?

Utility software plays a crucial role in computer systems by performing essential background tasks that maintain and manage the system's functionality. This type of software includes a variety of tools that help ensure the efficient operation of the computer, such as file management, disk management, antivirus functions, and backup and recovery activities. By executing these tasks, utility software enhances system performance, optimizes resource usage, and contributes to the overall reliability and stability of the system.

In contrast, the other options refer to different categories of software that serve distinct purposes. Creating documents and presentations is typically the function of productivity software, which is specifically designed for user-driven tasks. The option involving interfacing with users for productivity reflects the role of application software, which is focused on enabling users to carry out specific tasks. Connecting to external data sources pertains to database management systems or similar applications that facilitate data integration, rather than performing the background maintenance functions associated with utility software.
