PreviousA single processor system has three resource types X, Y and Z, which are shared by three processes. There are 5 units of each resource type. Consider the following scenario, where the column 'alloc' denotes the number of units of each resource type allocated to each process, and the column request denotes the number of units of each resource type requested by a process in order to complete execution. Find the process that will finish first and last. | | alloc<br>X Y Z | Request<br>X Y Z | |---|---|---| | P0 | 1 2 1 | 1 0 3 | | P1 | 2 0 1 | 0 1 2 | | P2 | 2 2 1 | 1 2 0 |NextConsider the following CPU processes with arrival times 0 and CPU bursts (in milliseconds) as given below: | Process | Burst time | |---|---| | P1 | 24 | | P2 | 3 | | P3 | 3 | If the Round Robin Scheduling is used with time quantum of 4 milliseconds to schedule the processes. Draw the Gantt chart and calculate the average waiting time across all processes (in milliseconds).
