Consider the following set of processes, with the length of the CPU burst
given in milliseconds:
Process Burst Time Priority
P1 2 2
P2 1 1
P3 8 4
P4 4 2
P5 5 3
The processes are assumed to have arrived in the order P1, P2, P3, P4, P5,
all at time 0.
a. Draw four Gantt charts that illustrate the execution of these
processes using the following scheduling algorithms: FCFS, SJF,
nonpreemptive priority (a larger priority number implies a higher
priority), and RR (quantum = 2).
b. What is the turnaround time of each process for each of the
scheduling algorithms in part a?
c. What is the waiting time of each process for each of these scheduling
algorithms?
d. Which of the algorithms results in the minimum average waiting
time (over all processes)?

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !

It is d shadow i hope it
