Use Tc = 10 ms and Tq = 50 ms in the questions below if relevant. 1) Consider the following processes in SJF scheduling policy: P1, requiring 200 ms, arrives in the queue at (t+0) ms P2, requiring 120 ms, arrives in the queue at (t+15) ms P3, requiring 60 ms, arrives in the queue at (t+25) ms a) Show the sequence of processes being executed (one can assume t to be 0... it is just a reference point). Making a table or chart will be helpful. b) Calculate the total processing time.
