Expert Solution & Answer
Chapter 9, Problem 14CSQ
Explanation of Solution
Problems faced by Target Canada:
Target Canada faced many problems and some of them are as follows:
- The company spent 7 billion dollars on increasing into Canada and was not likely to show its revenue till 2021. After many failures, all the 133 stores were closed, and 17,600 workers lost their jobs...
Explanation of Solution
People, Organization, and Technology contributed to those problems:
People had contributed to Target Canada’s problems:
Target’s management prefer for a new software package, thinking that it could be deployed faster, even if the company had small participation in using the new system. However, the managers underestimated the amount of time it might take to deploy the new system.
Organization had contributed to Target Canada’s problems:
Target rapidly moved to build three new massive distribution centers in Canada. Target Canada was not able to track their products or make sure that the right amounts of products were being ordered, stored, and shipped...

: The Multithreaded Cook
In this lab, we'll practice multithreading. Using Semaphores for synchronization, implement a
multithreaded cook that performs the following recipe, with each task being contained in a single Thread:
1. Task 1: Cut onions.
a.
Waits for none.
b. Signals Task 4
2. Task 2: Mince meat.
a. Waits for none
b. Signals Task 4
3. Task 3: Slice aubergines.
a. Waits for none
b. Signals Task 6
4. Task 4: Make sauce.
a. Waits for Task 1, and 2
b. Signals Task 6
5. Task 5: Finished Bechamel.
a. Waits for none
b. Signals Task 7
6. Task 6: Layout the layers.
a.
Waits for Task 3, and 4
b. Signals Task 7
7. Task 7: Put Bechamel and Cheese.
a.
Waits for Task 5, and 6
b. Signals Task 9
8. Task 8: Turn on oven.
a.
Waits for none
b. Signals Task 9
9. Task 9: Cook.
a. Waits for Task 7, and 8
b.
Signals none
At the start of each task (once all Semaphores have been acquired), print out a string of the task you are
starting, sleep for 2-11 seconds, then print out a string saying that you…
Programming Problems
9.28
Assume that a system has a 32-bit virtual address with a 4-KB page size.
Write a C program that is passed a virtual address (in decimal) on the
command line and have it output the page number and offset for the
given address. As an example, your program would run as follows:
./addresses 19986
Your program would output:
The address 19986 contains:
page number = 4
offset = 3602
Writing this program will require using the appropriate data type to
store 32 bits. We encourage you to use unsigned data types as well.
Programming Projects
Contiguous Memory Allocation
In Section 9.2, we presented different algorithms for contiguous memory allo-
cation. This project will involve managing a contiguous region of memory of
size MAX where addresses may range from 0 ... MAX - 1. Your program must
respond to four different requests:
1. Request for a contiguous block of memory
2. Release of a contiguous block of memory
3. Compact unused holes of memory into one single block
4.…

- Java Graphics (Bonus 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). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. 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.
