Fixed priority scheduling example
WebJan 24, 2024 · CPU Scheduling involves many different scheduling algorithms which have their Advantages and Disadvantages. 1. First Come First Serve (FCFS): Advantages: It is simple and easy to understand. Disadvantages: The process with less execution time suffers i.e. waiting time is often quite long. Favors CPU Bound process then I/O bound process. 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.

WebSep 1, 2024 · A better approach is designed by combining both preemptive and non-preemptive scheduling. This can be done by introducing time-based interrupts in priority based systems which means the currently running process is interrupted on a time-based interval and if a higher priority process is present in a ready queue, it is executed by … WebDec 28, 2024 · Examples to show the working of Preemptive Priority CPU Scheduling Algorithm Example-1: Consider the following table of arrival time, Priority, and burst time for five processes P1, P2, P3, P4, and P5 .
