JAVA TIMESLICE WINDOWS FULL
Of course, if someone is not too hungry or has a small appetite and is full after eating for 30 seconds, then he can tell the operating system: I am full (hang up). So, regardless of whether the 10 people have different priorities, different levels of hunger, and different appetites, everyone can eat for 1 minute when they come up. When the last person finishes eating, start over again. If the Unix operating system is responsible for dividing the cake, then he will set the rules like this: Everyone comes up to eat for 1 minute, and the time is up to replace the next one. Suppose there is a steady stream of cake (a steady stream of time), a knife and fork (a CPU), and 10 people waiting to eat the cake (10 processes). We describe these two algorithms with a split cake scenario. When the process is executed or hangs on its own initiative, the operating system will recalculate the total priority of all processes once, and then pick the one with the highest priority to give him control of the CPU. The operating system will hand over the CPU to the process with the highest overall priority. In a preemptive operating system, assuming there are several processes, the operating system will calculate a total priority for them based on their priority and starvation time (how long it has not used the CPU). Therefore, it can be seen that in a preemptive operating system, the operating system assumes that all processes are of "good character" and will actively exit the CPU. The so-called preemptive operating system means that if a process gets the CPU time, it will completely occupy the CPU unless it gives up the use of the CPU. All the scheduler has to do is maintain a list of ready processes, and when the process runs out of its time slice, it is moved to the end of the queue. If the process blocks or ends before the time slice ends, the CPU switches immediately. If the process is still running at the end of the time slice, the CPU will be deprived and assigned to another process. The operating system allocates a period of time to each process in their order, that is, the time that the process is allowed to run.

In the time slice algorithm, all processes are arranged in a queue.

Unix systems use a time slice algorithm, while Windows is preemptive. In the operating system, there are many strategies for CPU competition. Let's review the operating system principle first. Since it is Sleep 0 milliseconds, is there any difference compared to removing this code? A seemingly inexplicable sentence is used in someone's code: Thread.Sleep(0). So do you correctly understand the usage of this function? Consider the following two questions:ฤก. We may often use the Thread.Sleep function to suspend the thread for a period of time.
