The Reference Model is a conceptual framework for understanding how computers communicate. The OSI model defines seven different layers of communication rules. Each layer of the OSI model has its own means of communication or protocol. The OSI model is used as a reference when explaining how data passed over the network moves through each layer. Each of the seven layers has specific responsibilities and logically interfaces to the layer above or below it. Each layer in the OSI model provides a different service needed for communication across an IP network and physical media. The top three layers often are called the “upper layers” since they deal primarily with application data. The lower layers deal primarily with getting packets to their destination. Many refer to these layers as infrastructure. 

Questions:

1. For this discussion, compare and contrast two layers of the Open Systems Interconnection (OSI) Reference Model, including the protocols that run on each layer.

2. What was the reason that IPv6 was introduced?  Why do you think many organizations are not upgrading their network solely to IPv6 and run that protocol instead of running IPv4?  

3. What is the purpose of subnetting when using IPv4 addressing?  What role does subnet mask play in subnetting of IPv4?

Exp19_Excel_Ch07_CapAssessment_Shipping

Project Description:

You work for a company that sells cell phone accessories. The company has distribution centers in three states. You want to analyze shipping data for one week in April to determine if shipping times are too long. You will perform other analysis and insert a map. Finally, you will prepare a partial loan amortization table for a new delivery van.

Start   Excel. Download and open the file named Exp19_Excel_Ch07_CapAssessment_Shipping.xlsx. Grader has automatically added   your last name to the beginning of the filename.

The Week worksheet contains data   for the week of April 5.
 

  In cell D7, insert the appropriate date function to calculate the number of   days between the Date Arrived and Date Ordered. Copy the function to the   range D8:D35.

Next, you want to display the   city names that correspond with the city airport codes.
 

  In cell F7, insert the SWITCH function to evaluate the airport code in cell   E7. Include mixed cell references to the city names in the range F2:F4. Use   the airport codes as text for the Value arguments. Copy the function to the   range F8:F35.

Now you want to display the   standard shipping costs by city.
 

  In cell H7, insert the IFS function to identify the shipping cost based on   the airport code and the applicable shipping rates in the range G2:G4. Use   relative and mixed references correctly. Copy the function to the range   H8:H35.

Finally, you want to calculate a   partial shipping refund if two conditions are met.
 

  In cell I7, insert an IF function with a nested AND function to determine   shipping refunds. The AND function should ensure both conditions are met:   Total Days is grater than Total Days Delivery Goal (cell C3) and Order Total   is equal to or greater than Order Total Threshold (cell C2). If both   conditions are met, the refund is 50% (cell C4) of the Shipping Cost.   Otherwise, the refund is $0. Use mixed references as needed. Copy the   function to the range I8:I35.

The Stats worksheet contains   similar data. Now you want to enter summary statistics.
 

  In cell B2, insert the COUNTIF function to count the number of shipments for   Austin (cell B1). Use appropriate mixed references to the range argument to   keep the column letters the same. Copy the function to the range C2:D2.

In cell B3, insert the SUMIF   function to calculate the total orders for Austin (cell B1). Use appropriate   mixed references to the range argument to keep the column letters the same.   Copy the function to the range C3:D3.

In cell B4, insert the AVERAGEIF   function to calculate the average number of days for shipments from Austin   (cell B1). Use appropriate mixed references to the range argument to keep the   column letters the same. Copy the function to the range C4:D4.

Now you want to focus on   shipments from Houston where the order was greater than $1,000.
 

  In cell C7, insert the COUNTIFS function to count the number of orders where   the Airport Code is IAH (Cell D1) and the Order Total is greater than $1,000.   

In cell C8, insert the SUMIFS   function to calculate the total orders where the Airport Code is IAH (Cell   D1) and the Order Total is greater than $1,000. 

In cell C9, insert the MAXIFS   function to return the highest order total where the Airport Code is IAH   (Cell D1) and the Order Total is greater than $1,000.

On the Map worksheet, insert a   map for the states and revenues. Cut and paste the map in cell C1.

Format the data series to show   only regions with data and show all map labels.

Change the map title to April 5-9   Gross Revenue.

Use the Loan worksheet to   complete the loan amortization table.
 

  In cell F2, insert the IPMT function to calculate the interest for the first   payment. Copy the function to the range F3:F25. (The results will update   after you complete the other functions and formulas.)

In cell G2, insert the PPMT   function to calculate the principal paid for the first payment. Copy the   function to the range G3:G25.

In cell H2, insert a formula to   calculate the ending principal balance. Copy the formula to the range H3:H25.

Now you want to determine how   much interest was paid during the first two years.
 

  In cell B10, insert the CUMIPMT function to calculate the cumulative interest   after the first two years. Make sure the result is positive.

In cell B11, insert the CUMPRINC   function to calculate the cumulative principal paid at the end of the first   two years. Make sure the result is positive.

You want to perform a what-if   analysis to determine the rate if the monthly payment is $1,150 instead of   $1,207.87.
 

  In cell B15, insert the RATE function to calculate the necessary monthly rate   given the NPER, proposed monthly payment, and loan. Make sure the result is   positive.

Finally, you want to convert the   monthly rate to an APR.
 

  In cell B16, insert a formula to calculate the APR for the monthly rate in   cell B15.

Insert a footer on all sheets   with your name on the left side, the sheet name code in the center, and the   file name code on the right side.

Save and close Exp19_Excel_Ch07_CapAssessment_Shipping.xlsx.   Exit Excel. Submit the file as directed.

 The reading this week discusses strategy and how ERM can be integrated with an organization’s overall strategy. Prepare a research paper on some of the various issues, protocols, methods, frameworks you found and discuss how – if possible – organizations can use ERM as strategy. It is perfectly acceptable if you deem ERM cannot be used as strategy, just back up your claim with scholarly research and justifications.Your paper should meet these requirements: 

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA 7 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 and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.

Week 11 Discussion

What are some of the characteristics and operations of some of the malicious software that exists today?

Your post should be at least 350 words.

You have learned a great deal about the Internet Protocol (IP). IP is a set of rules for how data is sent across networks and arrive at the intended destination. An IP address is a numeric identifier assigned to each device on an IP network. Unfortunately, the internet has finally run out of IPv4 addresses. The good news is that everyone knew this would eventually occur and there is a solution: IPv6.

For this discussion, compare the characteristics of IPv4 and IPv6. Discuss any benefits one provides over the other.

Both IPv4 and IPv6 have the option to subnet. Some of the reasons to subnet a network is to improve network performance and speed, reduce network congestion, control network growth, and ease administration.

Next, select a Class A, B, and C IP (v4) address for input into the subnet calculator.

Class A: 1.0.0.1 – 126.255.255.254
Class B: 128.1.0.1 – 191.255.255.254
Class C: 192.0.1.1 – 223.255.254.254
Take a screenshot and post each of your results to include in your post.

If you want to increase the number of subnets, you simply change the Maximum Subnets field input to your desired number. When you increase this number, what happens to the Host per Subnet field and why?
