Operating Systems

1. At time O no system resources are being used except for the processor and memory. 2. Time slice is 100 cycles for each process. 3. The only user processes running are P1, P2, P3, P4,and P5. 4. These processes are queued in the natural order 1-5 and all have equal priorities. a) If none of the processes issues any command that triggers an interrupt, and none of the processes terminated, which process is running after 1150th cycle? b) If each process executes a read command from a different disc drive after 75 cycles of running, i. which process is running after 250th cycle? ii. in what states are the remaining processes? c) Suppose in part b), above, P1's read takes 400 cycles, while the reads of the remaining four processes take only 200 cycles. Which process is running after 375th cycle
