Os Process Management Questions
Context switching is the process of saving and restoring the state of a process or thread so that it can be resumed from the same point at a later time. It is necessary in operating system process management to allow multiple processes or threads to share a single CPU. When a process is interrupted or blocked, the CPU switches to executing another process, and the context of the interrupted process is saved. This allows the operating system to efficiently allocate CPU time to different processes, ensuring fairness and maximizing overall system performance.
