Under non-preemtive scheduling ,once the CPU has been allocated to process ,the process keeps CUP until it release CPU either terminating or switching to the waiting state .

What else can I help you with?
How do you create a non preemptive process?
There is no such concept of a "Preemptive Process"
Is windows xp preemptive or non preemptive?
It uses pre-emptive scheduling. It has what is called a pre-emptive multi-tasking kernel.
What is Non-preemptive algorithms?

Is the Linux kernel pre-emptive or non-premptive?
It is preemptive, as of the 2.6 series. 2.4 and prior were non-preemptive.
What is primitive and non-preemptive scheduling?
Non-Preemptive: Non-preemptive algorithms are designed so that once a process enters the running state(is allowed a process), it is not removed from the processor until it has completed its service time (or it explicitly yields the processor).context_switch() is called only when the process terminates or blocks.Preemptive: Preemptive algorithms are driven by the notion of prioritized computation. The process with the highest priority should always be the one currently using the processor. If a process is currently using the processor and a new process with a higher priority enters, the ready list, the process on the processor should be removed and returned to the ready list until it is once again the highest-priority process in the system.context_switch() is called even when the process is running usually done via a timer interrupt.
What are non preemptive scheduling algorithms?
Strictly speaking, nonpreemptive scheduling is when the scheduler does not stop the process from running in order to switch it with a different process, but instead, it lets the process to complete and then schedules a different process depending on the a scheduling algorithm is uses.
Does Windows 7 use preemptive scheduling or non-preemptive?
well sometime it does its just with the syames your useing.
What is the difference between preemptive and non preemptive scheduling?
1.) in preemptive scheduling we prempt the currently executing process, in non preemptive scheduling we allow the current process to finish its CPU burst time... 2.) in preemptive scheduling the process is forcibly sent to waiting state when a process with higher priority comes to CPU, in non preeemptive scheduling the process at running state can not be forced to leave the CPU until it completes........
Difference between preemptive and non preemptive?
if block Ki of size Ni is to be transferred to memory M1 & the blocks occupying the space in M1 can't be preempted by block Ki then it is necessaray to find or create a space of Ni words inM1 . this process is called non preemptive allocation....non preemptive allocation can't make efficient use of memory allocation.whenever preemptive allocation is used for efficient use of the available memory space and rellocation can be done.
What type of scheduling is there in RTOS?
A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.
What is the difference between pre emptive and non preemptive scheduling?
in pre emptive scheduling. a limited time period is fixed for every process in the CPU. no matter whether the process is completed or not ... the resource assinged to it will be taken back back abd will be given to the next process in the queue.while in non preemptive the resorces are with a process untill it finishes completely others wait for their turn till then. this kind of scheduling has a high probability of going into a deadlock.
What is Dispatch latency?
The time between when a thread is scheduled and when it begins to execute. Theoretically, in a preemptive OS the dispatch latency for a high-priority thread should be very low. However, in practice preemptive OSs are non-preemptive at times; for example, while running an interrupt handler. The duration of the longest possible non-preemptive interval is said to be the worst-case dispatch latency of an OS.
