IT332-4: Assess data communication and networking options for a computer system.

Purpose

The main focus of this assignment is performance factors and system implementations of clustering systems for a local area network (LAN) and a wide area network (WAN). Identifying the communication protocols of the OSI model can help network administrators plan and improve network performance and troubleshoot and avert errors that could take place during data transmission in a clustered system.

Assignment Instructions

Create a PowerPoint presentation of at least three slides that depict a cluster system connected over a LAN (local area network) and a WAN (wide area network). Include in the presentation each layer of the OSI model and clearly depict the communication protocols and devices that operate at each layer. Ensure that the following are represented in the presentation:

• A cluster where the systems are connected over a LAN.
• A cluster where the systems are connected over a WAN.
• In the diagram, provide a depiction of communication protocols and devices used at each layer of the OSI model.

Drawings may be performed using a presentation tool or exported from Microsoft Visio or Apache OpenOffice Draw.

Assignment Requirements

Be sure to use the appropriate APA format and cite your textbook or other sources that you used in your presentation.

The presentation should contain sufficient information to adequately answer the questions and contain no spelling, grammar, or APA errors. Points deducted from the grade for each writing, spelling, or grammar error are at your instructor’s discretion. 

For assistance with APA requirements, please go to Academic Writer. You will find the link in the Academic Tools section of the course.

Fun assignment:

Find a rotating cube with texture mapping. Show the original file, then replace the texture (picture) with one of your own – your picture.

Discuss the assignment in the “discussion assignment.”

Need to respond at least two students 

Design/Development:

1.  Consider a project that you have recently completed. What were some of the challenges that you personally faced while developing UI/API/DB/any others?

Were you able to overcome those challenges and if so, how were you able to overcome them?

At the same time, did you have to compromise or sacrifice anything in order to overcome the challenge? If so, how did you justify the compromises/sacrifices?

If there were other possible solutions to address the challenge, why did you pick one over the other?

2.  Describe a scenario from one of your recent projects where you used caching (Should be a project where you used Angular/AngularJS for UI, .NET RESTful Web API and SQL Server for the backend).

What was the reason you chose caching as the solution and how did you implement it?

Please also state the version used in the project for Angular, C# and SQL Server.

3.  You have been provided a technical design to implement. Based on your personal contributions on past assignments, explain your considerations and the analysis you would perform to make contributions or recommendations to improve the design provided using an example to achieve these contributions/recommendations and justify how your input added value to the overall result.

4.  You have been assigned to a project to modernize a client’s application portfolio. What would you consider modernization of an application?

What would you consider an appropriate application to modernize and why?

Provide an example of a most recent project that met the scenario mentioned and describe how the modernization added value.

5.  Using an example of a recent project where you personally have developed an entire module on your own. In that example what are the design considerations that you had to make and what are the advantages and disadvantages of the design?

Why did you decide to go with the design that you have at this point?

Maintenance/Troubleshooting:

6.  Describe a scenario when there was a performance problem in an application deployed to production (Should be an application where you used Angular/AngularJS for UI, .NET RESTful Web APIs and SQL Server for the backend). Please describe the tools that you used to troubleshoot the problem and how you found the root cause of the problem and what was the corresponding resolution. Please also state the version used in the project for Angular, C# and SQL Server.

7.  Users who are using an AngularJS application with REST API backend and SQL server 2016 are reporting that they are having an issue with the UI taking a very long time to load. How do you go about troubleshooting what the problem is?

URGENT NEED TO DONE 3 HOURS 

A Realtor in Massachusetts is analyzing the relationship between the sale price of a home (in $), it’s the square footage (in ft2), the number of bedrooms, the number of bathrooms, and a colonial dummy variable (colonial equals 1 if a colonial-style home; 0 otherwise). The relater collects data of 36 sales in Massachusetts for the analysis. The attached file “Assignment – Dataset 2” contains the data.

Address the following questions: 

a)  Develop a Neural Network (NN) prediction model for the sales price (Number of layers = 3, dense layers, activation function of “Relu”, number of nodes in each layer = 32).

b)  Predict the price of 2100 ft2 colonial style home with two bedrooms and two bathrooms.

c)  What are the limitations of the model?

Submit a PDF file for your answers as well as the excel sheet. Include the Python code in the PDF. 

 Once your team is in place and the scope of your disaster recovery planning is determined, the next step is to determine exactly what vital functions need to be included in the plan. Can you easily identify the most vital functions? What happens to the business if one or more functions are suddenly unavailable due to a system failure or other disaster? What is the cost if a function is unavailable? Intuitively, some functions must be more valuable than others, but what is that value? How can this value be measured? In a time of scarce resources, which functions need to be heavily protected and which (if any) can be safely ignored? In a major disaster affecting many functions, which functions are essential for the company’s survival?These questions are all pertinent. 
In your final research project for the course, your task is to write  a minimum of a 4-page  paper discussing these concepts:

• Introduction – What is Disaster Recovery
• Why Should an Organization evaluate risk?
• What are some Solutions in selecting a strategy?
• What is Important for a Technical Recovery Plan and Crisis Management Plan?
• Discuss at least one real organization that has been effective with implementing the Information Security Response.
• Conclusion – Final thoughts/future research/recommendation

The paper needs to be a minimum of 4 pages long, NOT including the title page and a references page (for a total of a minimum 4   pages). Be sure to use proper APA formatting and citations to avoid plagiarism.Your paper should meet the following requirements:

• Be minimum of 4 pages in length, not including the required cover page and reference page.
• Follow APA guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course, the course textbook, and at least FIVE scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find supplemental resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

• Describe how you would build a PC. Identify the parts used to build  the PC and their alignment to the PC’s primary use. Be specific with  details for each component. What component would you invest in the most?  Explain why.

The first thing we must know before building a computer is what the  purpose of this computer will be. Once we decide on the type of computer  we want to build, we can determine how good each of its components must  be so it can perform the way we need it.

One of my dreams has always been to have a super gaming computer, so I  based my project on this pc build. Please find below everything that I  will need to make my ideal PC a reality.

Motherboard: The motherboard support and connects  all components of a PC, and when it comes to a gaming computer the  motherboard allows the graphics card and processor to perform better. I  chose the MAG B560 TOMAHAWK WIFI Motherboard for my gaming PC.

Central Processing Unit (CPU): The CPU is the brain  of a computer. “This component is what helps the computer to process  input, store data, and output results. Without a CPU, we could not run  programs on a computer.” (CPU: Central Processing Unit | AP CSP ) ( n.d)

My choice for a CPU was Intel Core i9-10850K Comet Lake.

Operating System (OS): The OS is a software that  communicates with the hardware and allows other programs to run. I chose  for the project the professional version of Windows 10 as my OS.

Random Access Memory (RAM): “RAM is the part of your  device that functions like its short-term memory. It keeps track of  what programs are running in the background and what they’re doing, so  when you focus on them again, they can get right back to work.” (McCall,  2021)

I went with the CORSAIR – VENGEANCE RGB PRO for my project.

Hard Drive(s): Hard drive is an important component  for a gaming computer. This will provide storage for your games and (if  fast enough) support the graphics. I decided to go with a Solid-state  drive (SSD) instead of the HDD. SSD’s as we all know by now don’t have  moving parts, giving them an extra advantage over HDD. On top of that,  games will launch and load quicker when installed on an SSD.

Optical Drive: “An optical drive uses a laser or  visible light to read or write to optical discs such as DVDs, Blu-Ray,  and CDs from your computer.” (Optical drives )(n.d). ASUS  BW-16D1X-U Writable Blu-ray Drive was my choice for the project because  besides running in a Blu-ray format, it is also compatible with DVD and  CD format.

Video Graphics: A good graphic card is a very  essential thing to have if you are trying to build a decent gaming  computer. Current games are more advanced when it comes to graphics  capabilities and the size of the game itself, if you have a graphic card  that can’t keep up with these games, your computer won’t function how  you need it. GEFORCE RTX 3080 was my choice for this important  component.

Power Supply Unit (PSU): The power supply is the  beating heart of a PC. A great PSU will give you a longer-lasting  motherboard and will also increase the longevity of the other  components, including the graphics card and processor. I went with  Corsair RM750x as my PSU for my project.

Case: “The primary function of a computer case is to  protect the computer’s components from harm. A secondary function is to  easily transport the computer from place to place.” (What is the function of a computer case? )(n.d). My choice for my CPU Case is CORSAIR Obsidian 500D RGB SE Mid-Tower Case.

Monitor: The monitor is an output device that its  main responsibility is to display the final result of all of your  computer’s image rendering and processing. I selected the Samsung 49”  Odyssey G9 for my PC project.

Keyboard: The main function of a keyboard is to  operate the computer by sending it data. This data often consists of  characters (letters, numbers, line escapes), but can also tell the  computer to perform a function such as change the brightness or eject a  disk from the disk drive.

Mouse: The mouse is an input device that allows to perform different functions such as select and navigate through the PC.

For my computer project, I will spend most of the money on the  Graphics Card and the Monitor. The other components are extremely  important as well, but because I’m trying to build a gaming PC, I will  focus more on enhancing the game’s graphics than anything else.
