Course: Computer Architecture (Theme: Input-Output)

1. A computer consists of a processor and an I/O device D connected to main memory M via a shared bus with a data bus width of one word. The processor can execute a max of 2 MIPS. An average instruction requires 5 machine cycles, 3 of which use the memory bus. A memory read/write operation uses 1 m/c cycle. Suppose that the processor is continuously executing “background” programs that require 96% of the instruction rate but not any I/O instructions. Assume that one processor cycle equals one bus cycle. Now suppose the I/O device is used to transfer very large amounts of data between M and D.
   1. If programmed I/O is used and each one word transfer requires the processor to execute 3 instructions, estimate the max I/O data transfer rate in words/sec possible through D?
   2. Estimate the same rate if DMA is used?

Consider the following short cases. Connect each case with one of the three location techniques we talked about in class (linear programming, centroid or factor rating), answer the related question and explain why:

Lynn, Inc. is trying to locate a customer service center in a suburban area. They have population data for the various suburbs and villages around their area. They are interested in locating the center centrally with minimum distance between customers and the service center. In this technique two factors come into play – distance and _______. What is the missing word?

1. Fran, Inc. is trying to locate a distribution center for their products that they distribute to retail stores. Shipping cost is a major concern and the firm would like to minimize it. In this technique two factors come into play – shipping cost and ______. What is the missing word?
2. Orch is an insurance company that wants to relocate its headquarters. Managers are concerned with a number of items including education system, quality of life, tax rates and many others. There are two parts to the quantitative evaluation of this situation – they are ______ and _______ .

Risk Register

Assignment Content

1. Tony and his project team identified some risks during the first month of the Recreation and Wellness Intranet Project. However, all they did was document the risks in a list. They never ranked the risks or developed any response strategies. Because the project has had several problems, such as key team members leaving the company, users being uncooperative, and team members not providing good status information, Tony decided to be more proactive in managing risks and want to address positive risks as well as negative risks.

   Complete the following tasks:

   1. Create a risk register for the project. Identify 6 potential risks, including risks related to the problems described in the previous paragraph. Include negative and positive risks.
   2. Develop a 45- to 90-word response strategy for each risk. Enter the information in the risk register.
   3. Write a separate 175-word paragraph describing what specific tasks would be required to implement the strategy. Include time and cost estimates for each strategy.

Instructions: Need proper and complete answer (containing minimum 500 words) for following question related to 'Principles of Marketing'. Please include an additional listing of any references or supplemental materials used. Feel free to use whichever reference style you prefer. If you reference information from the Web or from any other sources (e.g., journal articles, library books, textbook), make sure that you do not copy the material verbatim (i.e., copied exactly from the original word for word). You should paraphrase (i.e., write in your own words) the information.

Question: Analyze a consumer or business product or service. To what segment(s) of consumers/businesses do you think it is targeted? Discuss the positioning of the product or service relative to competitors. How successful or unsuccessful has this positioning been? Would you suggest an alternative positioning or a repositioning? Why or why not? Identify any niches that might lend themselves to new products or services in the same category..

Question 1: Rucas plc is a telecommunications and information technology manufacturing company based in the country of Hambia. The currency of Hambia is the Aira (AR). The company is considering manufacturing the smart phone model H3XG. If the operation were to be set up, the equipment would be purchased for AR3.5 million and the market price at the end of expected 4-year project life will be AR1.25m. The mobile phone will sell for an initial price of AR950 per unit in the first year and this price will increase in line with inflation in Hambia which is expected to continue at the current rate of 6% per annum. It is expected that 3,000 H3XG phones will be sold in the first year, increasing at a rate of 3% each year. The costs of manufacturing H3XG will consist of variable costs which will be 60% of selling price per unit and incremental fixed overheads of AR60,000 per annum. The costs will increase in line with inflation in Hambia. The working capital equal to 10% of expected sales value for the year will be required at the beginning of each year. At the end of the project the working capital will be recovered. Corporation tax in Hambia is 25%, payable one year in arrears. The tax allowable depreciation is at 20% on a reducing balance method. The required rate of return for the project is 15%. YOU ARE REQUIRED TO:

(a) Estimate the net present value of the project, and recommend, on the basis of NPV, whether the project should be undertaken. (maximum word count for the recommendation 50 words).

(b) Explain why NPV is preferable to payback period as a project selection criterion. (maximum word count 100 words).

(c) Discuss any four non-financial objectives that a company should consider when making investment decisions. (maximum word count 100 words). TOTAL 50 MARKS
