Chapter 9, Problem 9SG
Program Plan Intro
Multitasking:
- Multitasking is a technique in which Central Processing Unit (CPU) makes the user to perform the instructions from multiple programs at a time.
- It switches over between the programs and instructions.
- It involves one CPU which works with multiple programs.
- OS is the term that acts as an interface between the hardware and the user.
- It is the first
program loaded into the computer memory whenever the computer starts up. - It is responsible for the management and co-ordination of activities on a computer system.
- The most important program that runs on a computer is operating system.
- OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.
- OS controls the peripheral devices like printers, hard drives and mouse.
- The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.

Lab 07: Java Graphics
(Bonus lab)
In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to
implement the following:
➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a
Point (see java.awt.Point) in a PointCollection class (you need to build this).
о The points need to be represented by circles.
Below the drawing panel, you will need 5 buttons:
о
An input button to register your mouse to the drawing panel.
○
о
о
A show button to paint the points in your collection on the drawing panel.
A button to shift all the points to the left by 50 pixels.
The x position of the points is not allowed to go below zero.
Another button to shift all the points to the right 50 pixels.
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.…
If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A.
(a) Give an example of when an application might want to receive such ICMP messages.
(b) Find out what an application has to do, on the operating system of your choice, to receive such messages.
(c) Why might it not be a good idea to send such messages directly back to the originating port P on A?

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forwardusing r languagearrow_forward8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class.

Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.
