- SHORTEST JOB FIRST SCHEDULINGAIM:To write a program to implement cpu scheduling algorithm for shortest job firstscheduling.ALGORITHM:1. Start the program. Get the number of processes and their burst time.2. Initialize the waiting time for process 1 as 0.3. The processes are stored according to their burst time.4. The waiting time for the processes are calculated a follows:for(i=2;i<=n;i++).wt.p[i]=p[i=1]+bt.p[i-1].5. The waiting time of all the processes summed and then the average time is calculate6. The waiting time of each processes and average time are displayed.7. Stop the program.Each function has local memory associated with it to hold incoming parameters, local variables, and (in some cases) temporary variables. This region of memory is called a stack frame. Question 7 options: True FalseCPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority. Your program should first prompts the user to input a list of process ID, arrival time, burst time, and priority for each process to be run on the CPU. The list is terminated by 0 0 0 0 for the process ID, arrival time, burst time, and priority. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the Priority scheduling algorithm. Also print the turnaround time, response time, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.
- Shortest-Remaining-Time-First (Preemptive SJF): Write a Java program to implement a Shortest-Remaining-Time-First (Preemptive SJF) scheduling algorithm. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.Question 1: Write a C program that creates two processes (P1 and P2). P1 should prompt the user to enter positive integer numbers until it receives 0. It sends every integer to its P2. P2 computes the number of all the integers divisible by 3 and send the result to P1. P1 should displays the result.Write the mnemonics of the following program: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78, 65, 89, 56, 75
- A "service" transaction results in a print request being removed from the priority queue and the customer name being displayed on the console. A transaction containing the string "end-of-file" will signal the end of the input. Your program will display the number of print requests remaining in the queue when the "end-of-file" transaction is processed. Sample input transactions and output expected using a priority queue: 2-01-guo 1-02-hannie 3-03-ian service (output: 1-02-hannie) service (output: 2-01-guo) 1-04-danny 3-05-eli 1-06-fan service (output: 1-04-danny) service (output: 1-06-fan) end-of-file (output: There are 2 remaining print requests in the queue.) 1Write a C program that creates four child processes and passes num1 and num2 to them using execvp. Child1: Add the passed numbers. Child2: Subtract the passed numbers. Child3: Multiply the passed numbers. Child4: Divide the passed numbers.Correct and unique answer please i will upvote. CPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority.

- • Write a c program that creates a child process. the parent should read 2 integers x and y from the user the parent should send x and y for the child via pipe the child should read the integers via pipe and finally display the sum of these 2 integers. Once the child display the sum, the parent should display "Done!I can go now"It is possible to demonstrate the return address of a function by using a series of instructions. Keep in mind that any modifications to the stack must not prohibit the process from returning control to the person who called it.Concurrent Server Programming TITLE: Quiz Game In this assignment you are asked to write a phyton system to support an online math contest. The contest consists of answering the maximum quantity of sums in 30 seconds. This is done in a concurrent way, which means, that there are three participants answering at the same time. The participant with most correct answers WINS. The jury is responsible in starting up the server, after that they wait for the clients. When the three clients are connected, they must send the message: READY to the server. When the server receives the three READY from the clients, the contest starts. At the end of the program, the server must show the results .Execution (SERVER) - Please provide me the complete code and solution to arrive to the results below.python3 MathinikServer 192.168.1.2 Connected192.168.1.2 is Anne192.168.1.4 Connected192.168.1.4 is Billy192.168.1.3 Connected192.168.1.3 is MarkMark is READYAnne is READYBilly is READYStarting Contest…Contest…
