Prepare First Come First Serve algorithm to evaluate the following performance metrics, but not limited to:
(i) Turnaround time of the jobs;
(ii) Waiting time of the jobs; and
(iii) Number of interrupts incurred

Table 1: Sample of job lists Job (3) arrive at CPU cycle 36 I/O (45) CPU (48) I/O (55) I/O (51) CPU (55) I/O (34) CPU (43) CPU (48) CPU (60) I/0 (33) CPU (48) CPU (59) CPU (44) I/O (41) CPU (35) CPU (38) I/O (59) CPU (37) I/O (57) I/O (41) I/O (41) Job (1) arrive at CPU cycle | Job (2) arrive at CPU cycle 2 CPU (54) I/O (40) CPU (48) CPU (43) I/O (46) I/0 (39) I/O (53) I/0 (35) CPU (48) CPU (41) CPU (31) CPU (60) CPU (55) I/0 (37) CPU (57) CPU (60) CPU (33) I/O (42) I/O (39) CPU (32) CPU (35) I/0 (32) CPU (20) CPU (39) I/O (44) I/O (45) CPU (34) I/O (57) CPU (32) CPU (59) CPU (42) CPU (33) CPU (60) CPU (40) CPU (35) CPU (44) I/O (56) I/O (58) I/O (31) I/O (58) CPU (57) CPU (43) Note: Each job has mixture of CPU and I/O instructions, and the integer between the brackets indicates CPU or I/O cycle required for each instruction Еxample: CPU (20) – The integer 20 represents the computational instruction requires 20 CPU cycle to compute. I/O (40) – The integer 40 represents the I/O instruction requires 40 I/O cycle to complete.
