Chapter 9, Problem 2E
a)
Explanation of Solution
Walls and Doors:
Walls and doors act as the obstacles and prevent form stealing resources or information...
b)
Explanation of Solution
Access Control:
Access control is categorized into two. They are:
Physical access control: The objective of physical access control is to guard the physical resources of a particular organization. The physical resources may be people, systems, hardware and so on.
Logical access control: The objective of physical access control is to guard the critical data that could be taken by an intruder without accessing physical devices. They are technology-based control that includes intrusion detection system, antivirus software, and firewalls.
Factors considered for the server room:
The organization will consider many security controls to protect their resources and precious data...
c)
Explanation of Solution
Fire detection:
Fire detectors are used to find out the phenomena resulting from fire like, smoke, gas, ultraviolet radiation, infrared radiation, etc. By using fire detectors, it is possible to save lots of lives and protects assets in an organization...
d)
Explanation of Solution
Fire suppression:
- Fire suppressor is used to eliminate fire from particular areas. They are of portable and manual types. Mostly portable extinguishers are more efficient for smaller fire.
- Fire suppression system quells fires by eliminating either oxygen or fuel, or it reduces the temperature.
- Fire extinguishers usually contain carbon-di-oxide that eliminates oxygen supply. It might harm living beings so they are not used in residential areas...
e)
Explanation of Solution
Heating, Ventilating, and air conditioning:
Heating, ventilation as well as air conditioning system could have impact on operations of
f)
Explanation of Solution
Power quality and distribution:
In order to avoid power quality, proper UPS should be used. They act as a backup power supply for computers. The powering capacity of UPS is usually measured in volt-ampere. A normal computer uses 200 VA and during interruptions or power fluctuations, it gets efficient power supply from UPS which provides up to 1,000 VA...

: 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.

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. " 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. Regardless of how…arrow_forward
