The prompt presents a question about the functions of operating systems and asks which option is NOT a function. We will evaluate each choice in turn to understand why it is or isn’t a function of an OS.
Option 1: 'To make computers easier to use' This is a core function of an OS. Operating systems provide user interfaces, manage resources, and hide hardware complexity to simplify usage, making the computer easier to operate for users. Therefore this option describes a valid function.
Option 2: 'None of these' This would imply that all the listed statements are functions of an OS. Since one option is indeed not a function (see Option 4), choosing 'None of these' would be incorrect because at least one statement is not a function.
Option 3: 'To control application software' An OS does not control application software in the sense of managing its internal behavior; rather, it provides services (APIs, system calls, scheduling, memory management) that applications use. The OS controls resources and provides a platform for applications, but it does not control application software in the sense of directing its logic. Depending on interpretation, this could be seen as a borderline claim, but the more standard view is that the OS manages hardware and provides services rather than controlling how each application functions.
Option 4: 'To make computers work faster' This statement describes performance optimization, but the OS does not directly make the hardware run faster in the sense of increasing hardware speed. It does enable efficient scheduling, resource management, and caching, which can improve perceived performance, but saying 'to make computers work faster' is not a fundamental function of an OS; performance optimization is a consequence rather than a primary function. This makes it the best candidate for NOT being a core function.
In summary, each choice represents a potential interpretation of OS roles. The analysis shows that while operating systems aim to make using the computer easier and to provide necessary management services, they do not primarily control application software, and they do not literally increase hardware speed. Among the options, the statement that most clearly does not describe a fundamental OS function is the fourth one, which asserts that the OS makes computers work faster.
