- Process Scheduling: Select all statements below that are true The CPU burst is the amount of time a process obtains the services of a processor as a whole. Arbitration becomes necessary when two processes with equal priority are to be scheduled. Since resource sharing is the main focus of multi-programming, it essential to allow the scheduler to remove (pre-empt) processes from the CPU in response to changing circumstances. 0 When preemptive scheduling is applied, a process is allocated the CPU until it releases it again. The service time is also known as the turnaround time. The short-term scheduler selects which of the ready, in-memory processes is to be executed next.Assignment for Computer Architecture Instructions: The assignment is to create a program that adds the number 1/2 to itself a large number of times and adds the number 1/3 to itself a large number of times separately first using type float and then type double. It is to then compare the values of adding the numbers to multiplying 1/2 time the number of times added to compute the “same sum” in a different way. The program will also multiply 1/3 times the number of times 1/3 was added to itself to compute the “same sum” in a different way. The program will then compare these two methods at arrive for the same value and output the difference. Hint, the value for the ½’s will be the same for the smaller numbers of times, the 1/3’s will never be the same. The output from your program is to be to a *.txt file which you are to turn in along with your code. The program must first add the ½’s and 1/3’s using type float and compare to the value obtain using multiplication instead of addition.…The code box below defines a variable route as a list of directions to navigate a maze. Each instruction is one of the following four basic commands: • higher. move one step in the positive y direction • lower: move one step in the negative y direction • left: move one step in the negative x direction right: move one step in the positive x direction ● Define a function move that takes two arguments, a location (as a tuple of x and y coordinates) and an instruction (higher, lower, left, right) as a string. Given the provided location, it should return the new location (as a tuple of x and y coordinates) when following the specified instruction. If the instruction is invalid, the old location should be returned. Use the function move to determine the final position when starting from the point (-2, -1) and following all instructions in the list route. Assign this final position to the variable final_location. Reset answer 1 route = ['right', 'higher', 'left', 'lower', 'higher', 'left',…

Please modify the code so that this is trackable, try to find the best allocation of tickets to processes to get as close as possible to the expected CPU percentage allocation. Please show modification in the code this is C program #include #include #include #include // global ticket count int gtickets = 0; struct node_t { int tickets; struct node_t *next; }; struct node_t *head = NULL; void insert(int tickets) { struct node_t *tmp = malloc(sizeof(struct node_t)); assert(tmp != NULL); tmp->tickets = tickets; tmp->next = head; head = tmp; gtickets += tickets; } void print_list() { struct node_t *curr = head; printf("List: "); while (curr) { printf("[%d] ", curr->tickets); curr = curr->next; } printf("\n"); } int main(int argc, char *argv[]) { if (argc != 3) { fprintf(stderr, "usage: lottery \n"); exit(1); } int…An complete operation does not need to be in memory before it may be executed, according to the approach of
