Explanation of Solution
Hardware:
- Hardware is a general term which refers to physical components of the computer system.
- There are different kinds of hardware that can be installed inside and outside of a computer.
- Computer components found inside the computer Motherboard, Central Processing Unit (CPU), Random Access Memory (RAM), Hard Disk and many such.
- Computer components found outside the computer Monitor, Keyboard, Mouse, Printer and many such...

Principal issues in managing hardware and software technology:
- If an electromechanical or electronic component in a system experiences a fault, it is known as hardware failure. To rectify the fault, the component should be repaired or replaced...
Explanation of Solution
Capacity planning and scalability of technology resources:
- The operation that tries to determine the necessary bandwidth amount required to support an application or set of applications in the organization is referred to as capacity planning.
- There are four different techniques to perform capacity planning,
- Linear projection: Based on the current network parameters, one or more new network capacities are predicted.

Benefits of outsourcing:
- Outsourcing is the process of providing the subcontract of job to the third party.
- It reduces the cost, energy, and time, and it is similar to globalization.
- Globalization of job is the important technology that affects the employment.
- Nowadays, the product is not developed and sold in the same country...
Explanation of Solution
Benefits of cloud computing:
- Cloud computing is a type of computing that relies on computer resources sharing rather than the application running on local computing devices such as servers, computers, tablet, and Smart phones.
- In a cloud computing the cloud is used as a symbol for the internet, it means that the cloud computing is a type of internet based computing.
- The general characteristics of cloud computing are:
- On-demand self service
- The customer or the subscriber of the cloud, without communicating to the human from the cloud provider, can increase or decrease the computing requirements on demand.
- The computing requirements are server, network storage, and software applications.
- Broad network access
- The broad network access is an important component of cloud computing.
- The services provided by the cloud provider must be accessible over the network from any location and any standardized platform.
- Resource pooling
- Resource pooling is the ability to provide the services to multiple subscribers for their need at the same time...
- On-demand self service

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.

The two other classes are Attraction and Entertainment.arrow_forwardObject-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. 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. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo!

For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.
