1 In Linux, when a timer expires, there is a context switch so that the CPU scheduler can run.

False

True

2 The operating system keeps track of CPU usage for all processes.

False

True

3 A system call that does not invoke the CPU scheduler executes in the same context as the process that makes the call.

False

True

4

A ____ synchronizes access to memory from devices that want to access it.

In UNIX, the system call to perform input from a device is named ___.

2.3At the lowest level of processing, we manipulate bits in the framebuffer. In WebGL, we can create a virtual framebuffer in our application as a two- dimensional array. You can experiment with simple raster algorithms, such as drawing lines or circles, through a function that generates a single value in the array. Write a small library that will allow you to work in a virtual frame- buffer that you create in memory. The core functions should be WritePixel and ReadPixel. Your library should allow you to set up and display your vir- tual framebuffer and to run a user program that reads and writes pixels using gl.POINTS in gl.drawArrays.

2.4 Turtle graphics is an alternative positioning system that is based on the concept of a turtle moving around the screen with a pen attached to the bottom of its shell. The turtle’s position can be described by a triplet (x, y, θ), giving the location of the center and the orientation of the turtle. A typical API for such a system includes functions such as the following: init(x,y,theta); // initialize position and orientation of turtle forward(distance); right(angle); left(angle); pen(up_down); Implement a turtle graphics library using WebGL. All this using Html file below and editing it

Access control can be considered as the central element of computer security. Question 4(a), 4(b), 4 (c) and 4(d) based on this information.

4 (a). Relate the principal objective of computer security with the function of access control.

4 (b). Briefly explain how access control being implemented in the machine.

4 (c). If Process A requires 500MB of memory space to perform calculation and Process B requires 100MB of memory space to perform graphics processing, identify the object, subject and access operation in this scenario. Provide explanation for your answer.

4 (d). Company RT wants to have different access levels for each of its users. A management level employee will have more privileges to files and operations. The executive level will have moderate privilege to the files but individual users will have their own level of control to the files they own. Which type of access control is suitable for this company and its employee? Clearly explain and justify your answer.

Your objective is to write a well-documented simple program using classes, a loop, and nested ifs to simulate an ATM using JAVA.

1. Create an ATM class with class variables name, pin, and balance, a constructor with parameters to assign values to the three instance variables, methods to get the name, pin, and balance, and methods to handle validated deposits and withdrawals ( deposit and withdrawal amounts cannot be negative, and withdrawal amount must not be greater than the existing balance).

2. In the ATMTest class, read the names, 4 digit pin numbers, and account balances of two customers into two instances of the ATM class. Display the two customers names, pins, and balances formatted.

3. Now that you have all your customers’ information start your ATM to accomplish the following within an infinite loop,

a). Display a welcome screen with your bank’s information and prompt for and read the customer entered pin.

b). Use a nested if to match the entered pin with one of the two customers’ pins. If the entered pin number matches that of one of the customers, then:

i. Welcome the customer by name and display the balance.

ii. Display option to 1. DEPOSIT, 2. WITHDRAW or 3. EXIT.

iii. If option 1 is selected, then use the instance deposit method to prompt for deposit amount, read, and add a valid deposit amount to the customer’s balance

iv. If option 2 is selected, then use the instance withdrawal method to subtract a valid withdrawal amount from the customers balance

v. If option 3 is selected, go to step a.

4. Should the entered pin number not match either of the two customers, notify the customer that the entered pin is not valid and go to step a.

5. Selection of the EXIT option must display welcome/login screen (step a).

6. Should an incorrect option be entered, notify the user and display the original welcome/login screen (step a).

Please lists the IDE you used for the project.

This question has been answered before. I need a new, slightly modified code for the following:

A palindrome is a word that it reads the same left to right and right to left. For this programming assignment, you need to write a C++ program that does the following:

• Request the user to enter a string.
• Write a recursive function that will test the string to validate if it is a palindrome or not.
• Respond back with an output saying if the original string was a palindrome or not.

Please provide new code along with screenshot of output.

Explain how Apple Inc. customers will place an order, how the order will be delivered and how the process for complaints will be handled.

This question has been answered already however, I'd like some new examples.

Task: In C#, create a minimum of three try/catch statements that would handle potential input errors. Thank you.

Java questions. Please answer everything. It mean the world to me. Thank you very much

1. Identify the errors in the following code fragment:

   1: ArrayList<String> list = new ArrayList<String>();
   2: list.add( "Denver" );
   3: list.add( "Austin" );
   4: list.add( new java.util.Date() );
   5: String city = list.get( 0 );
   6: list.set( 2, "Dallas" );
   7: System.out.println( list.get(2) );

2. Explain why the following code fragment displays [1, 3] rather than [2, 3].

   1: ArrayList<Integer> list = new ArrayList<Integer>();
   2: list.add(1);
   3: list.add(2);
   4: list.add(3);
   5: list.remove(1);
   6: System.out.println( list );

3. Describe the difference between passing a parameter of a primitive type and passing a parameter of a reference type. Then show the output of the following program:

    1: class Test {
    2:     public static void main ( String [] args ) {
    3:         Count myCount = new Count();
    4:         int times = 0;
    5:         for ( int i = 0; i < 100; i++ )
    6:             increment( myCount, times );
    7:         System.out.println( "count is " + myCount.count );
    8:         System.out.println( "times is " + times );
    9:     }
   10:     public static void increment ( Count c, int times ) {
   11:         c.count++;
   12:         times++;
   13:     }
   14: }
   15: 
   16: class Count {
   17:     public int count;
   18:     public Count ( int c ) {
   19:         count = c;
   20:     }
   21:     public Count () {
   22:         count = 1;
   23:     }
   24: }

4. What is wrong in the following code?

   1: public class Test {
   2:    public static void main ( String [] args ) {
   3:       java.util.Date[] dates = new java.util.Date[10];
   4:       System.out.println( dates[0] );
   5:       System.out.println( dates[0].toString() );
   6:    }
   7: }

5. If a class contains only private data fields and no “set” methods, is the class considered to be immutable?
6. If a class contains only data fields that are both private and primitive, and no “set” methods, is the class considered to be immutable?
7. What is wrong in the following code?

    1: public class C {
    2:     private int p;
    3: 
    4:     public C () {
    5:         System.out.println( "C's no-arg constructor invoked" );
    6:         this(0);
    7:     }
    8: 
    9:     public C ( int p ) {
   10:         p = p;
   11:     }
   12: 
   13:     public void setP ( int p ) {
   14:         p = p;
   15:     }
   16: }

8. What is wrong in the following code?

   1: public class Test {
   2:     private int id;
   3:     public void m1 () {
   4:         this.id = 45;
   5:     }
   6:     public void m2 () {
   7:         Test.id = 45;
   8:     }
   9: }
