Define the three overarching domains that contain application software, system software and hardware layers along with the
layers of abstraction in each, and explain in detail how each of these layers, whether software or hardware, interacts with the
others. Explain your answer in 3-5 sentences.
Answer:
The three overarching domains that contain application software, system software and hardware layers are:
- The kernel: This is the lowest level of software, and it interacts directly with the hardware.
- User space: This is where most applications live, and it is separate from the kernel to protect the stability of the system.
- Shells and GUIs: These provide a way for the user to interact with the system.
The hardware layer is the lowest level, and it consists of the actual physical components of the system. The software layers sit on top of the hardware, and they are responsible for running the system. The application software is the highest level, and it consists of the programs that the user runs. The system software is in the middle, and it consists of the operating system and other utilities that manage the system.
Explanation:
Hope this helps!
The three overarching domains in computing are application software, system software, and hardware layers, which interact through standardized interfaces and protocols to execute tasks and processes seamlessly.
Overarching domains in computing represent distinct layers, where application software serves as the user-facing programs tailored to specific tasks, system software acts as a mediator managing essential system functions and services, and hardware encompasses tangible components like CPUs, memory, and devices.

Write a program that inputs the length of two pieces of wood in yards and feet (as whole numbers) and prints the total.
Sample Run:
Enter the Yards: 3
Enter the Feet: 2
Enter the Yards: 4
Enter the Feet: 1
Sample Output:
Yards: 8 Feet: 0
The program accepts separate fabric lengths in feet and inches and displays the total fabric length in feet and inches.
What is programming?Creating a set of instructions that tells a computer how to perform a task is known as programming. Computer programming languages such as JavaScript, Python, and C++ can be used to create programs.
The Python 3 program is as follows:
feet_1 = int(input('length in feets : '))
Prompts user to enter feet length of fabric 1
inch_1 = int(input('length in inch : '))
Inch length of fabric 1
feet_2 = int(input('length in feets : '))
Feet length of fabric 2
inch_2 = int(input('length in inch : '))
Inch length of fabric 2
inch_sum = inch_1 + inch_2
Sum of the inches
inch_left = inch_sum%12
Remainder in inches after converting to feets
inch_to_feet = inch_sum // 12
Whole number of the converted inch sum
feet_sum = feet_1 + feet_2 + inch_left
Total sum of the feet length
print('Feet : %d Inches : %d' %(feet_sum, inch_left))
Display the sum
Thus, this can be the format for given scenario.

Do you believe that software manufacturers should be tolerant of the practice of software piracy in third-world countries to allow these countries an opportunity to move more quickly into the information age? Why or why not? What would the benefits and disadvantages of this be?
Answer:
I do not believe that software manufacturers should be tolerant of the practice of software piracy in third-world countries. I believe that this would be a disservice to the software manufacturers, as well as to the countries themselves.
The benefits of software piracy are that it allows countries to have access to software that they would otherwise be unable to afford. However, the disadvantages are that it encourages people to pirate software instead of buying it, which hurts the software industry. It also means that people in these countries are using software that is not licensed, which could lead to security and stability issues.
