Creating multiple processes can be time consuming and computationally expensive ting the traditional fork" system call. Briefly discuss some other better approaches to this Is marks . Compare and contrast any two ways in which Os can be structured. Be sure to point out how one addresses the flaws in others 15 marks c. There are five processes A co to run. Their arrival times are 0, 1, 3, 12 seconds respectively. Their CPU but are 3.5. 2.5 and 5 seconds, respectively. What is the average turnaround time using First come first served, Shortest-job-first and round robin (with 1 second quantum) [6 mural What quantum time will you support in a round-robin) for a better performance Chigh response time, low waiting me etc.) 12 marlo d. Often time, Round Robin outperforms 'CFS algorithm. Can these two algorithms ever have the same tumaround time? When? c. Abdullah Grocery store has an application that generates the monthly sales report. The app generates a file named "items.txt" and have the following fields: ItemId, Item Name, ItemAmount, ItemPrice, Purchase Date in this order. Perform the following operation on the file. 1. List the top ten most expensive item and 10 least expensive items ii. Create a new file"extra.txt" that will contain only the Item Name, Item Price and Purchase Date [6 marks] QUESTION THREE 1. Creating multiple processes can be time consuming and computationally expensive ting the traditional fort system call. Briefly discuss some other better approaches to this I marks! 1. Compare and contrast any ewo ways in which OS can be structured. Be sure to point out how one address the flaws in others 15 marks ci. There are five processes to to run.
