WebPreemptive Scheduling. 1: a process switches from the running state to the ready state, 2: when a process switches from the waiting state to the ready state. This type of scheduling can stop a running task before completion so another task can use the CPU. Issues with synchronization. WebA process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.To meet these requirements, the OS must …
