WebFor example, if a high-priority task is waiting for an event, it should not sit in a loop (poll) for the event because by polling it is always running, and so never in the Blocked or Suspended state. Instead, the task should enter the Blocked state to wait for the event. WebThere are six popular process scheduling algorithms which we are going to discuss in this chapter −.
