What is defined as system software?

System software is essentially the foundation of a computer system. It serves as the intermediary between the hardware and the user applications, ensuring that the hardware functions seamlessly and efficiently. This type of software includes operating systems, device drivers, and utilities that manage computer resources.

The correct answer highlights that system software is responsible for running the computer, managing hardware operations, and providing a platform upon which application software can execute. It enables the computer's components—such as CPU, memory, storage, and input/output devices—to communicate effectively, creating a functional environment for both users and applications.

In contrast, software that helps users accomplish tasks falls under application software, as it pertains directly to user interactions and specific functions rather than hardware management. Storing information relates more to data management systems rather than the underlying operating structure of the computer. Likewise, software that secures against unauthorized access is considered security software, which operates on top of system software rather than being classified as system software itself.
