a.
Program Plan Intro
2D graphics:
The shape that can be laid flat on a piece of paper or any mathematical plane is known as a 2D shape. Only horizontal and vertical directions are used in 2D that is it contains only length and width. It is used for printing and drawing application.
3D graphics:
3D graphics is a three dimensional representation of the geometrical data. It contains length, breadth and depth.
a.
Expert Solution
Explanation of Solution
Determine whether designing the layout of magazines pages is application of 2D or 3D graphics:
- The magazine page has its length and breadth but the depth of the page is negligible.
- This means that the dimension of the page is limited to horizontal and vertical axes that are X and Y-axis.
- So, in case of designing the layout of the magazine page various shapes, sizes and colors can be designed, but as the paper does not contain any depth, it is a 2D graphics application.
Therefore, designing the layout of the magazine page is “application of 2D graphics”.

Explanation of Solution
Determine whether drawing an image using Microsoft paint is application of 2D or 3D graphics:
- The dimension of Microsoft page is limited to horizontal and vertical axes that are X and Y-axes.
- So, In case of drawing an image using Microsoft paint, the position of the mouse pointer is located in between two coordinates only and so it is also an application of 2D graphics.
Therefore, drawing an image using Microsoft paint is “application of 2D graphics”.

Explanation of Solution
Determine whether producing image from a virtual world for a video game is application of 2D or 3D graphics:
- The appearance of the screen of the video game on which images is displayed is 2D, but producing an image from a virtual world for a video game causes a series of images to view with subtle isometric variation to copy or mimic object as these objects are viewed in the real world.
- So, through interaction, user also experiences the depth of the object.
Therefore, producing image from a virtual world for a video game is “application of 3D graphics”.

1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.
Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.

All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed.
