ProcessArrival TimeBurst

I have attached a file with 4 questions. Any help would be appreciated. Thanks!

 

READ THE PROBLEM STATEMENTS CAREFULLY.Problem 1:ProcessArrival TimeBurst TimeP102P211P324P432P541Consider a set of processes given above with the arrival time and the length of CPU burst timegiven in cycles. Show a Gantt chart and calculations of average turnaround time and averagewaiting time of these processes under the shortest job first (SJF)withpreemption CPUscheduling algorithm and the round-robin scheduling algorithm with a time quantum of 1 cycle.(10 points)Problem 2:Assume that the OS is using a memory paging method, memory pages are1024words long, instructions are8-wordlong, and each address in memory accesses only one word.A page table for a particular process is given below:Page Number Frame Number0710223441Calculate a starting physical memory address for each of the following instructions. If theaddress cannot be calculated using the page table and the given info, say why not.(5 points)oinstruction #52oinstruction #369oinstruction #512oinstruction #612oinstruction #640Problem 3:From a given reference string below, show a snapshot of physical memory framesafter each memory page is accessed under the OPT and LRU page replacement policies then
