The Open Systems Interconnect

Description:

The Open Systems Interconnect (OSI) model is a conceptual model that characterizes and standardizes the internal functions of a communication system by dividing network communication functions into abstraction layers. The OSI model groups similar communication functions into one of seven logical layers. The questions below are based on internal functions of some of the OSI layers.

(a) In a communication system that is based on a layered OSI model, packet segmentation is to ease transmission of data packets over the network. Since packet segmentation performs functions that are associated with specific protocols and the OSI layer, answer the following questions:

1. What are the three functions of packet segmentation?

2. What protocols perform packet segmentation?

3. What layers of the OSI model are involved with packet segmentation?

(b) Network bridging and switching occurs on one of the layers of the OSI seven layers. The questions below are based on network bridging and switching.

(4) On which OSI layer do network bridging and switching functions occur?

(5) What are the similarities and differences between a network bridge and a switch?

Please answer the questions in a 4–6-page paper. As you answer each question, you must provide support or evidence that will enhance and empirically prove your answers. Academic IT articles or real-life IT findings that are not found in journals or other academic sources must be used in supporting your answers. Please use APA style for all cited sources, including your reference page.

Please address the following requirements in your 4–6-page paper:
  • A title page
  • A report that includes the following:
    • An introduction to the contents of the report
    • An explanation of the OSI network model as it relates to network segmentation, bridges, and switches

Please cite your references in APA format.

Please submit your assignment.

JLB Enterprises: Managing Performance

JLB Enterprises: Managing Performance

JLB Enterprises is a computer manufacturer that is experiencing low employee motivation.  Evidence shows that efficiency has decreased 15% over the last two years while other factors, including the number of employees, have remained the same, and the process to assemble computers has remained the same as well.

Additionally, the 2011 annual employee survey shows that employee satisfaction and morale have decreased significantly (a 20% decline) over the last 3 years.  A recent survey of employees conducted by an outside consulting firm confirmed that employees do not feel motivated.  On a scale of 1 to 10, with 1 being “not motivated” to 10 being “very motivated,” the average of all reported results was 5.5.

Recent examples of research studies that have demonstrated a link between motivation and performance.  JLB Enterprises has a problem in that employee performance has declined over time.  This is a problem because lower performance means fewer products built for the same amount of time and money.  Therefore, efficiency has declined and costs have increased.

List and define one of the leadership theories that may serve as a lens to view JLB Enterprises’ current problem.

Then, using the components of the theory, show how the characteristics of the theory may potentially inform strategies for improving this performance problem.

Remember, your thoughts, feelings, and opinions must be supported with facts, statistics, testimonials, examples, cases and other references in critical thinking.  Research and facts support critical thinking efforts.

Your essay should be approximately 500 words (two typed, double-spaced, APA-formatted pages), well written, and documented per graduate guidelines for APA Style.
A cover page and References page are required.
Be sure to use proper punctuation, spelling and grammar; points will be deducted accordingly.
Support your analysis by referencing and citing sources when needed. It is suggested that you cite at least three credible sources.  Sources must be cited according to APA guidelines.

The Value of Compound Interest for Investments

Assignment 4.1: The Value of Compound Interest for Investments

In this course project assignment, you will research the value of compounding interest (or reinvesting all gains) for investments.

Click on the “Project” tab on the top navigation bar for details on the course project.

Procedure

  1. Assume your company has $25,000 available to invest for 10 years. The investment may be broken down into $5,000 increments.
  2. Make an assumption about the company’s risk-return trade-off tolerance. Write a statement about your assumption.
  3. Choose investments from the following list that meet the company’s risk tolerance:
  • Cash-on-hand checking account, 0% interest
  • Savings account at 1½% interest, compounded annually
  • CD’s at 3%, compounded bi-annually
  • Bonds at 7% interest, compounded bi-annually
  • Mutual funds at 10%, compounded quarterly
  • Stocks at 15%, compounded quarterly

For example: you may choose $5,000 in Cash-on-hand; $10,000 invested in CD’s; and $10,000 invested in Bonds.

  1. Using Table 12.1 “Future Value of $1 at Compound Interest” inPractical Business Math Procedures (text), calculate the value of the investment in each account after the 10 year time period for each investment chosen. Compute the total for the investment.
  2. After you have organized your thoughts, post your recommendation for how the company should invest the $25,000 to the course Forum.

Canada Life Insurance as a Risk Manager – Assignment Instructions

Just imagine that I am working at Canada Life Insurance as a Risk manager

Greer (2001) describes the growing use of contingent workers who, unlike permanent and core employees, usually have only a short-term affiliation with the organization. These workers include “temporaries, subcontracted workers, part-time workers, consultants, life-of-the-project workers, and leased employees” . The contingent workforce is particularly common in unbundled or network organizations where non-core activities or activities outside the expertise of the firm are outsourced.

Similarly, Handy (1993) contends that the future will see more Shamrock organizations, modelled on the three leaf clover. The three leaves of the Shamrock represent the following:

  • A core workforce—These are managers, technicians, professionals, and skilled workers who are essential to the organization. They are well paid and well looked after. They are expected to do whatever is needed to complete essential tasks and keep the organization together. They are expensive, so there are not many of them.
  • A contractual fringe—In the 1980s large organizations began to shed support staff (e.g., cleaning, printing, delivery, legal staff, nurses, etc.) who were frequently expensive and underemployed. Companies are now contracting out more and more of what they used to do in-house.
  • A flexible labour force—Organizations are no longer storing workers so they will be able to cope with peak periods without overtime. However, they do not want to overload core workers when there is pressure to get things done. It ischeaper, if less convenient, to hire occasional help, part-time employees, or temporary employees at lower rates.

The extreme is the virtual organization which has a small head office staff with almost all activities contracted out. Handy cites an example of a German manufacturer of garden equipment who subcontracted manufacturing, design,accounting and finance, and franchised the sales operation. He then closed his office and now operates out of his Mercedes with a cell phone.

Please discuss the following questions with your colleagues.

  • In your area of work, which tasks could be done by outsiders (either other organizations or individuals)? What would be the advantages and disadvantages of contracting out such tasks?
  • What would it be like to manage in a Shamrock organization—to be holding the leaves together?
  • If you were to move into the contingent workforce, what impact would it have on your personal life? What advantages or difficulties would such a change create for you?
  • Are contingent work and Shamrock organizations where we should be headed? What are the implications of this approach to HRM for demographics, global competition, and the economy? If more and more organizations move toward the Shamrock structure, what do you think will be the implications for society? Is this move for better or for worse?
