Briefly describe the most common methods for making priority-based scheduling decisions
Commonly used methods include first-come first-served (FCFS), shortest time remaining (STR), and explicit priority. With FCFS, the scheduler dispatches the thread that has been waiting the longest; with this method, the run queue is ordered by wait time. With STR,the next thread to be dispatched is based on the expected amount of CPU time needed to complete the process.Creating, updating, and using time-to-completion information increases system overhead, so this method isn't used often. Explicit prioritydispatches threads based on priority level.A priority level can be assigned to a newly created thread based on the default priority of the process owner, a priority stated explicitly in an OS command, or other methods.
