answer for part 1 is provided.I need answer for part 3 context switching At arrival time 0, we have 2 processes P1 and P2 with same priority 3 So, according to Shortest Remaining Time First policy, P1 with burst time of 15 P1 0 15 After 15 secs, no other process has arrived and Process P2 is executed for 5 secs and then new processes has arrived. But, Process P2 has the highest priority when compared to the new processes. So, it completely gets executed P1 P2 0 15 35 Now, all the processes have arrived and P3 P4 P5 has the same priority. So, according to SRTF policy, P5 is executed and then P4 and P3 P1 P2 P5 P3 P4 0 15 35 40 50 70 Now, the only remained process of P6 is executed P1 P2 P5 P3 P4 P6 0 15 35 40 50 70 85 Step 2 Thus, the…
