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........
What is pre-emptive multitasking?
In preemptive multitasking scheduling processes , scheduler can interrupt one running process and and allocate CUP to another process without letting the complete the task of first process. Window 95 introduced preemptive scheduling and Mac also uses this scheduling process. Bharat Rawal
What kind of process algorithm is used in mac os x?
scheduling algorithm
Definition of scheduling in operating system?
the objective of multiprograming is to have some processs running at aal time,so as to maximizing cpu utillization .this process is called scheduling.
How do you perform shortest remaining time scheduling?
Shortest Remaining Time First (SRTF) scheduling is a preemptive scheduling algorithm that selects the process with the smallest remaining execution time to run next. When a new process arrives, the scheduler compares its remaining time to the currently running process. If the new process has a shorter remaining time, the current process is preempted, and the new process is scheduled to run. This continues until all processes are completed, ensuring that shorter tasks are prioritized for execution.
Dynamic job shop scheduling?
dynamic job shop scheduling is the scheduling of the machine it can processes different jobs at time. it switches from one job to another job. in real time process jobs are executed based on the time.
What is the relation of SJF scheduling to priority scheduling?
Shortest Job First (SJF) scheduling and priority scheduling are both CPU scheduling algorithms used in operating systems to manage process execution. SJF selects processes based on the shortest estimated execution time, while priority scheduling selects processes based on their assigned priority levels. In some cases, SJF can be viewed as a specific type of priority scheduling where the priority is inversely related to the job length—the shorter the job, the higher its priority. Thus, both approaches aim to optimize CPU utilization but differ in the criteria they use for process selection.
What is a preemptive and non preemptive algorithm and explain with example?
Preemptive scheduler reruns scheduling decision when process becomes ready. If the new process has priority over running process, the CPU preempts the running process and executes the new process. Non-preemptive scheduler only does scheduling decision when running process voluntarily gives up CPU. In effect, it allows every running process to finish its CPU burst.

What is average waiting time in round robin scheduling in operating system?
the total time that staying in the queue that wait for process of each process.
Round robin scheduling program in java?
Round robin is the scheduling algorithm that is utilized by the CPU, or central processing unit, during the execution of the process. It is specifically designed for time sharing systems.
