Detailed explanation-1: -Processor management is an execution unit in which a program operates. The operating system determines the status of the processor and processes, selects a job and its processor, allocates the processor to the process, and de-allocates the processor after the process is completed.
Detailed explanation-2: -Processor Management This function of OS is called process scheduling.
Detailed explanation-3: -In multiprogramming environment, the OS decides which process gets the processor when and for how much time. This function is called process scheduling. known as traffic controller.
