What is the main function of system software?

The primary role of system software is to ensure the operating system functions effectively and efficiently. System software acts as a mediator between the computer hardware and application software, providing a platform for applications to run. It includes the operating system itself, device drivers, and utility programs that help manage the system resources.

By maintaining the operational integrity of the operating system, system software allows users to carry out tasks on their devices without needing to understand the underlying hardware architecture. This software manages system resources such as memory, processing power, and input/output devices, ensuring that all components cooperate smoothly to support the applications that users interact with.

While the other choices may describe functions related to applications or specific aspects of computing, they do not encapsulate the overarching purpose of system software as effectively as this option does. For instance, developing user applications pertains more to application software, managing network traffic relates to network software, and creating graphical user interfaces involves application design rather than the foundational role of the operating system.
