Which of the following is not the function of operating system?1 pointClock ManagementMemory managementProcess management

To determine which option is not a function of an operating system, let's analyze the functions listed:

1. Clock Management: This typically refers to how an operating system utilizes the system clock for scheduling tasks and managing time. This function is indeed part of an operating system’s responsibilities.

2. Memory Management: This is a fundamental function of an operating system, involving the handling of memory allocation, deallocation, and management of memory resources to ensure efficient processing.

3. Process Management: This function includes the management of processes within the system, overseeing the execution of processes, allocation of CPU time, and handling of process scheduling.

Now, based on the analysis above, all three terms mentioned—Clock Management, Memory Management, and Process Management—are indeed functions of an operating system. However, if we need to choose one that is less commonly referred to in basic overview than the others, it could be argued that Clock Management is less of a focus in comparison to more prominent functions like Memory and Process Management.

Final Answer: Clock Management is the option that is not primarily highlighted as a core function of operating systems in typical discussions.
