Explanation of Solution

The below code is given in the textbook “Listing 1.2”.

Program:

//Import required packages

import javax.swing.JApplet;

import java.awt.Graphics;

//Definition of class "HappyFace"

public class HappyFace extends JApplet

{

    //Definition of method "paint()"

    public void paint(Graphics canvas)

    {

        //call the "super" method

        super.paint(canvas);

        //Method invocation to draw the outline of face

        canvas.drawOval(100, 50, 200, 200);

        //Method invocation to draw the eyes

A3Q3.c - You are to write a C program that implements the following disk scheduling algorithms: a. FCFS [10 marks] b. SCAN [10 marks] c. C-SCAN [10 marks] d. SSTF [10 marks] e. LOOK [10 marks] f. C-LOOK [10 marks] • Your program will service a disk with 300 cylinders numbered 0 to 299. • • • • The program will service the requests (a list of 20 cylinder numbers) given in the file request.bin. This file contains (4 byte) integer values representing requests ranging from 0-299. Your program will take the initial position of the disk head as the first command line argument and the direction of the head as the second command line argument. It will then output the requests in the order in which they are serviced, and the total amount of head movements required by each algorithm. In particular, your program needs to do the following: Your program should take two command line arguments a) First command line argument - initial position of the disk head (an integer value) b) Second command line…
2. The memory management has contiguous memory allocation, dynamic partitions, and paging. Compare the internal fragmentation and external fragmentation for these three approaches. [2 marks] 3. Suppose we have Logical address space = 24 = 16 (m = 4), Page size=2² =4 (n = 2), Physical address space = 26 = 64 (r = 6). Answer the following questions: [4 marks] 1) Total # of pages ? 2) Total # of frames ? 3) Number of bits to represent logical address? 4) Number of bits to represent offset ? 5) Number of bits to represent physical address? 6) Number of bits to represent a page number? 7) Number of bits to represent a frame number / 4. What is translation look-aside buffers (TLBS)? Why we need them to implement the page table? [2 marks] 5. Why we need shared pages for multiple processes? Give one example to show the benefits. [2 marks] 6. How to implement the virtual memory by using page out and page in? Explain with an example. [2 marks] 7. We have a reference string of referenced page…
8. List three HDD scheduling algorithms. [2 marks] 9. True or False? The NVM has the same scheduling algorithms with HDD. Explain why? [2 marks] 10. Why the modern mouses use polling to detect movements instead of interrupts? [2 marks] 11. What is thrashing? How does it happen? [2 marks] 12. Given a reference string of page numbers 7, 0, 1, 2, 0, 3, 0, 4, 2, 3, 0, 3, 0, 3, 2, 1, 2, 0, 1, 7, 0, 1 and 4 frames show how the page replacement algorithms work, and how many page faults? [6 marks], 1) FIFO algorithm? [2 marks] 2) Optimal algorithm? [2 marks] 3) LRU algorithm? [2 marks] 13. List at least three file systems that you know. [2 marks] 14. In C programming, how the seek to a specific position in the file by offset? [2 marks]
