Consider the following set of processes, with the length of the CPU burst time

Process Arrival time Burst time

P$1030$

P$2520$

P$31010$

P$47040$

P$57030$

a$)$ Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms

$$ First$-$ Come, First$-$Served $($FCFS$)$ Scheduling

$$ Shortest$-$Job$-$First $($SJF$)$ Scheduling

$$ RR $($quantum $=10)$

$$ Multiple level with $3$ Queues:

o Q$1$ : RR with quantum $10$

o Q$2$: RR with quantum $20$

o Q$3$: FCFS

b$)$ What is the turnaround time and response time of each process for each of the scheduling algorithms in part a$?$

c$)$ Calculate the average waiting time for the first three algorithms
