5. In a multiprogramming system using Round Robin (RR) scheduling with a 5ms time quantum, three processes arrive in the following order with their CPU burst times: Process P1 P2 P3 Burst Time (ms) 8 12 6 a. Draw the execution timeline showing how the scheduler allocates the CPU to each process until all complete. b. Calculate the waiting time for each process. c. Compute the system's average waiting time. 6. You are a system administrator responsible for managing the memory allocation of a computer system that employs fixed-size partitions. Lately, you've noticed that despite having sufficient total memory, there seems to be a considerable amount of unused space within each partition. Upon closer examination, you realize that this unused space is impacting the system's performance. a. Identify the observed inefficiency in the memory allocation scheme described above. Explain how this inefficiency could affect the overall performance of the system. b. Question 2: Suggest the solution to the problem described above. Describe the advantages of implementing this method over the current approach.
