In the Shortest Job First scheduling algorithm, the priority of a process is … Splet31. jan. 2024 · P1 has higher priority than P2. The execution begins with process P1, which has burst time 4. Step 1) At time=1, no new process arrive. Execution continues with P1. Step 2) At time 2, no new process arrives, so you can continue with P1. P2 is in the waiting queue. Step 3) At time 3, no new process arrives so you can continue with P1.

Splet07. sep. 2016 · This is a preemptive algorithm which means that the CPU can leave a process while under execution, and can move to the next process in the queue. Meanwhile, the current state of the process is saved by context switch and another job can be processed in the meantime.
