What is co-operating scheduling?
CPU scheduling decisions may possibly place under the following four circumstances:
1. When process switches from the running state to the waiting state
2. When process switches from running state to the ready state.
3. When process switches from waiting state to the ready state.
4. When a process terminates.
When scheduling occurs only under circumstances 1 and 4, we state that the scheduling scheme is cooperative or nonpreemptive. Here formerly the CPU has been allocated to a process the process keeps the CPU until it releases the CPU either terminating or by switching to the waiting state. Cooperative scheduling is the merely method that can be used on certain hardware platform for the reason that it does not require especial hardware needed for preemptive scheduling.
