• addling hew processes, • input data about the new process; • view of information about the system time; • choice of the scheduling algorithm. Processes are modeled by the program as some data structures. There is no need to create and track real processes. You need to select 2 algorithms from the list below and implement a process scheduling mechanism. In addition, it is necessary to develop a set of tests that demonstrate the advantages and disadvantages of a given scheduling algorithm. For example, for a priority scheduling algorithm with static priorities, a situation should be tested when a process with a low priority cannot enter the execution state for a long time. Options:

- Read this Paragraph and answer the Given question: A A&A that runs a chain of hospitals in Karachi has decided to start a new computer program to manage patients, admit-in, and discharge of patients. Currently, A&A has software that can carry out these tasks for an individual hospital. This is problematic since, for example, if one hospital is full and receives a new patient request, the A&A tries to locate a suitable bed in another of its hospital; it is then necessary for hospital management to ring around the other hospitals. Similar problems arise if a patient wants to transfer to another hospital that has better facilities. A&A requires a new web application that should resolve the existing system problem by implementing a single, common patient admission and discharge system across the whole chain. Additionally, the A&A wishes to gain a competitive edge with a frequent-guest program to encourage repeat patient who readmits will be given discounts and other…2. Write programs in eitherCor Java or python (choose your preference ) to simulate the following scheduling Algorithms with their respective Gantt Charts displayed during run time: (i) FCFS- First Come First Serve Scheduling (ii) SJF- Shortest Job First Scheduling (Non - Preemptive and Pre-emptive both) (iii) LJB-Longest Job First Scheduling (Non - Preemptive and Pre-emptive both) (iv) Priority Scheduling (Non - Preemptive and Pre-emptive both)For the following problem, please do not provide me any code. I will give you my code please check it and make corrections as necessary.

- A function that writes directly into log of operating system, isTopic: Concepts of programming Language Kindly provide a bit detailed answer 4. a) Consider the following program, written in JavaScript-like syntax:// main programvar x, y, z;function sub1() {var a, x, z;. . . }function sub2() {var a, b, y;. . .}function sub3() {var a, y, w;. . .}Given the following calling sequences and assuming that dynamic scoping isused, what variables are visible during execution of the last subprogramactivated? Include with each visible variable the name of the unit where it isdeclared.“main calls sub1; sub1 calls sub3; sub3 calls sub2.”Please write a C program. Consider the following code snippet in your main function -a = fork();b = fork();c = fork();Now, write the full program, that will check the children’s PID and if it is odd then the processwill create another child process. Lastly, print how many processes have been createdconsidering the first parent process
- Please explain step by step how processes are created. 1. Including the parent process, how many processes are created by the following program? Assumethat all fork() system calls succeed. #include <unistd.h>#include <stdio.h>int main(int argc, char **argv) {for (int i = 0; i < 3; i++)fork();/* ... */}2. Given the following program, please determine how many times the word “hello” is printed out.Assume that fork() is always successful. #include <sys/types.h>#include <stdio.h>int main() {pid_t a, b;a = fork();b = fork();if (a == 0)b = fork();if (b == 0)a = fork();printf(“hello\n”);return 0;} 2.

A. -15 B. -3 C. -16 D.- 31 E. -7 Which statement is true about dynamic typing? A. the binding of a function call and the function definition occurs at compile time B. the binding of a function call and the function definition occurs at run time C. the binding of the type of a variable and the variable name occurs at run time D. the binding of the type of a variable and the variable name occurs at compile timePlease Implement in C programming Language Given the list of processes, their CPU burst times, arrival times, and priorities implement the Priority scheduling algorithm on the processes with preemption. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Waiting time: Processes need to wait in the process queue before execution starts and in execution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference between submission time and completion time).
