Answer:
Scheduling queues in a Process State:
Job queue: The functionality of job queue is to store all the processes initially when they entered the system.
Ready queue: The functionality of ready queue is to store all the processes that are in the main memory, ready and waiting for execution. In other words, processes that are in the ready state are placed in ready queue.
Device queue: The functionality of the device queue is to store all the process that are waiting for I/O devices.

Breadth First Search algorithm, process scheduling, graph theory, and congestion handling in networks are some applications of queues. The two core operations in queues include enqueue () for insertions on one end, and dequeue () for deletions from the other end, size() returns the size of the queue, front() returns the first element in the queue, empty() determines if the queue is empty. Considering the lines give below, write a c program that implements enqueue and dequeue operations and print...

Cpu scheduling
Consider the following set of processes, with the length of the CPU burst times given in milliseconds:a. Draw four Gantt charts illustrating the execution of the processes using FCFS, Preemptive SJF, a non-preemptive priority, and a RR (quantum=2) scheduling. (30 pts)Note: for the RR consider that the arriving time is 0 for all processesb. What is the average waiting time of each process for of the above scheduling algorithms?
