CHAPTER 2: MINI-CASE I. DEALS-R-US BROKERS (PART 1)
Question 1: Classify the two alternatives in terms of what type of application architecture they use.

a. The first suggested solution is a client-based architecture since it’s the client that tells the server what data to select to analyze, making the client perform most of the work. b. The later architecture is two-tier Client-Server architecture since it requires an application layer, in this case, a web browser and all processing is done by the server. The server is responsible for the data and the client, the application and presentation. Using the web browser the client will talk to the web server using HTTP standard.

Question 2: Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better.
Solution 1: Client-based Pros 1. This method will be much more inexpensive to implement as micro-computers are considerably cheaper versus mainframe. 2. Hardware devices from different manufacturers/platforms can function together on the same network.
Solution 1: Client-based Cons 1. Data always flows through the network between the client and the server. 2. So much data traffic on the network between client and host could put a significantly slow down the network thereby affecting performance and response time.
Solution 2: Two-Tier Client-Server Pros 1. Performance in this method will be better as processing is distributed to multiple machines (in this case, multiple web servers). 2. The cost of infrastructure is low as they place less of a load on networks and thus require less network capacity.
Solution 2: Thin-Client Cons 1. More expensive as more web-servers will be involved. 2. Slower in processing compared to solution one as processing over the network is much slower that that fully downloaded and processed locally.…...

Chapter 5 Mini Case

...Chapter 5: Mini Case 2 - Central University Central University Suppose you are the network manager for Central University, a medium-size university with 13,000 students. The university has 10 separate colleges (e.g., business, arts, journalism), 3 of which are relatively large (300 faculty and staff members, 2,000 students, and 3 buildings) and 7 of which are relatively small (200 faculty and staff, 1,000 students, and 1 building). In addition, there are another 2,000 staff members who work in various administration departments (e.g., library, maintenance, and finance) spread over another 10 buildings. There are 4 residence halls that house a total of 2,000 students. Suppose the university has the 128.100.xxx.xxx address range on the Internet. How would you assign the IP addresses to the various subnets? How would you control the process by which IP addresses are assigned to individual computers? You will have to make some assumptions to answer both questions, so be sure to state your assumptions. As a network manager, I would assign the IP addresses to various subnets by associating a subnet base address with each physical network. Then I would sequentially assign hosts particular IP addresses within the subnet. Determining host addresses is really quite simple, once we know the subnet address. You should be able to substitute the numbers for the host ID bits in the subnet address. Then convert the address to decimal form. By controlling which IP addresses assigned......

Part 2, Chapter 1 Summary, 1984

...Part 11, chapter 1 Summary: Chapter I At work one morning, Winston walks toward the men’s room and notices the dark-haired girl with her arm in a sling. She falls, and when Winston helps her up, she passes him a note that reads, “I love you.” Winston tries desperately to figure out the note’s meaning. He has long suspected that the dark-haired girl is a political spy monitoring his behavior, but now she claims to love him. Before Winston can fully comprehend this development, Parsons interrupts him with talk about his preparations for Hate Week. The note from the dark-haired girl makes Winston feel a sudden, powerful desire to live. After several days of nervous tension during which he does not speak to her, Winston manages to sit at the same lunchroom table as the girl. They look down as they converse to avoid being noticed, and plan a meeting in Victory Square where they will be able to hide from the telescreens amid the movement of the crowds. They meet in the square and witness a convoy of Eurasian prisoners being tormented by a venomous crowd. The girl gives Winston directions to a place where they can have their tryst, instructing him to take a train from Paddington Station to the countryside. They manage to hold hands briefly, in which time Winston “learned every detail of her hand”, but dare not look into each other’s eyes. Character details: Winston: * revealed to still experience moments of empathy, despite his thought that the girl may be an enemy,......

Chapter 1 Case Study 2

...Chapter 1 : Case Study 2 Providing any form of compensation could be taken as an offense for thousands of donor families who have already made a benevolent choice of donating organs. The proposed legislation could also end up alienating families who have decided to donate life saving organs regardless of any compensation. Many may think that offering economic benefits, wether directly or indirectly in exchange for organ donations or assigning monetary value to the human body, or body parts, is inconsistent with our values as a society. The proposed legislation could also promote suicidal behavior in people who are in need of monetary help or want to help out their family and loved ones. By offering financial incentives, there could be an increase in crimes such as organ stealing and possibly murder for receiving money for the stolen organ. These are the few issues that this proposed legislation raises. Even though the proposed legislation raises the above mentioned issues, I would still support the the bill. Providing financial incentives for organ donation might seem like it diminishes human dignity, however, it could be something worth looking into. In the normal world, people are naturally resistant to things they are not familiar with or cannot relate to. Economic incentives might force them to rethink their options about organ donation. The proposed legislation may not deter people who believe it is wrong but, it will cause a large population to consider organ......

Chapter 1 Case 1 and 2 Case Study

...Case 1 1. What skills does Black think employees need to work successfully in the area of HR? Case1 – The skills that Black thanks employees need to work successfully in HR is for them to be commercial, challenging, and focused on delivery and excellence. They must also understand change and transformation, excel at operations, and balance tactical and strategic thinking and acting. They will have to be able to manage and navigate organizational complexity and ambiguities and not be afraid to say no in order to establish boundaries with the business. I agree with what Black says but I also feel you need to have good communication skills and more importantly, listening skills. You need to take the time to listen to others and see how they are doing and see if they know of any ideas or areas where things can improve. 2. What are some of the outcomes of the company’s new HR strategy? Case1 –The outcomes of the company’s new HR strategy has been great.

...1. Find a list of all 10 of Zappos corporate values. Pick two of the values and explain how you think those values would influence the way employees do their work. A. Zappos list of 10 corporate values are: Deliver WOW Through Service, Embrace and Drive Change, Create Fun and A Little Weirdness, Be Adventurous, Creative, and Open-Minded, Pursue Growth and Learning, Build Open and Honest Relationships with Communication, Build a Positive Team and Family Spirit, Do More with Less, Be Passionate and Determined, and Be Humble. If I had to pick two values from that list they would be Build a Positive Team and Family Spirit and also Build Open and Honest Relationships with Communication. I believe that these two values would have the biggest impact in developing an organizations culture. Organizational culture has been described as the shared values, principles, traditions, and ways of doing things that influence the way organizational members act and that distinguish the organization from other organizations. Organizational culture has many characteristics but the book uses 3 particular words to define culture: Perception, Descriptive, and Shared. An organizations culture cannot be physically touched or seen, the organization is concerned with how members perceive the culture and how the describe it and finally individuals with different backgrounds or work at different levels of the organization can describe the culture of the organization in similar terms. When the key......

...Deal-R-Us Brokers A) Classify the two alternatives in terms of what type of application architecture they use. 1. Alternative One: The first alternative will have a special tool developed in C++ that clients will download onto their computers to run. The tool will communicate with the DRUB server to select data to analyze.  – This alternative would be client based architecture. The client gives the command to the server. 2. Alternative Two: The second alternative will have the C++ program running on the server; the client will use his or her browser to interact with the server. – This alternative would be two tier thin client server architecture. This requires a web browser, a server and application layer. B) Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better. Alternative One – Client Based Architecture. Pros: 1. This is an affordable alternative since microcomputers are cheaper than mainframes and it does not take long periods to implement. 2. On a client based architecture, varying hardware manufacturers can cross function. Cons: 1. All data on the server must travel to the client for processing; this can lead to an overload of the circuits on the network since far more data than is needed is usually transmitted. Alternative Two – Two Tier Thin Client Server Architecture Pros: 1. There is a balance of processing since both the server and the client do the same processing making the system...

...[pic] Robert Half International, Inc. 22 WAYS TO STRIKE OUT WHEN INTERVIEWING A recent survey was conducted among 150 companies to discover why a candidate who is capable of handling a job is not hired. The responses all relate to the crucial interview period. Twenty-two inevitable ways to “strike out” are listed below. If you really want the job, be careful to avoid them all. 1. POOR PERSONAL APPEARANCE A company will be more likely to hire someone who is well groomed and will represent their company in a professional manner. 2. LACK OF INTEREST AND ENTHUSIASM A passive and indifferent attitude is instantly recognized as “I don’t care if I get this job.” Sincere interest and enthusiasm about the position is essential. 3. TOO MUCH EMPHASIS ON MONEY Your interviewing goal is to sell yourself to the interviewer and get an offer of employment. Salary discussion is secondary. 4. CONDEMNATION OF PAST EMPLOYERS Present facts only surrounding the past positions. Interviewers will be sensitive to comments about past employers. Too much information may come across as gossip. 5. TALKING TOO MUCH Answer questions as asked without being abrupt; expound only to the point that the interviewer has a clear understanding of what you mean. Unnecessary conversation wastes time. 6. WEAK HANDSHAKE The interviewer’s first impressions are lasting impressions. A firm handshake shows confidence in yourself and you abilities. 7. REFUSAL TO TRAVEL......

Chapter 9 Mini Case

...Chapter 9 Mini Case During the last few years, Harry Davis Industries has been too constrained by the high cost of capital to make many capital investments. Recently, though, capital costs have been declining, and the company has decided to look seriously at a major expansion program proposed by the marketing department. Assume that you are an assistant to Leigh Jones, the financial vice president. Your first task is to estimate Harry Davis’s cost of capital. Jones has provided you with the following data, which she believes may be relevant to your task: (1) The firm’s tax rate is 40%. (2) The current price of Harry Davis’s 12% coupon, semiannual payment, non callable bonds with 15 years remaining to maturity is $1,153.72. Harry Davis does not use short-term interest-bearing debt on a permanent basis. New bonds would be privately placed with no flotation cost. (3) The current price of the firm’s 10%, $100 par value, quarterly dividend, perpetual preferred stock is $116.95. Harry Davis would incur flotation costs equal to 5% of the proceeds on a new issue. (4) Harry Davis’s common stock is currently selling at $50 per share. Its last dividend (D0) was $3.12, and dividends are expected to grow at a constant rate of 5.8% in the foreseeable future. Harry Davis’s beta is 1.2, the yield on T-bonds is 5.6%, and the market risk premium is estimated to be 6%. For the own-bond-yield-plus judgmental-risk-premium approach, the firm uses a 3.2% risk premium. (5) Harry Davis’s......

Chapter 6 Mini Case

...Meghan Michel 9/8/2015 Finance 403 Chapter 6 Mini Case a. What effect did the expansion have on sales and net income? Sales increased 70% off of the $3,432,000 in 2014 to $5,834,000 in 2015. Revenue went up by 2.4 million dollars but cost of goods sold went up by 2.1 million dollars therefore it is of no surprise that EBIT fell Net income fell from $87,960 to ($95,136) despite the 70% increase in sales due to the 2.6 million dollar increase in total operating expenses. What effect did the expansion have on the asset side of the balance sheet? Assets nearly doubled from $1,468,800 to $2,886,592, and net fixed assets increased by $594,990 from $344,800 to $939,790. The purpose of increasing assets is to generate more revenue, but in this case Computron did not generate enough to justify the investments. The inventory rose from $715,200 to $1,287,360 and accounts receivable almost doubled increasing to $632,160 in 2015 from 2014’s $351,200. What effect did it have on the liabilities and equity? The financing needed for the expansion caused the current liabilities to increase from $481,600 to $1,328,960. Long term debt increased to help with financing but no new stocks were issued b. What do you conclude from the statement of cash flows? This statement of cash flows shows the impact of buying and selling fixed assets, cash transactions with shareholders, and the borrowing and repaying lenders to pay for the expansion.

DRUB is a small brokerage house that enables its clients to buy and sell stocks over the Internet, as well as place traditional orders by phone or fax. DRUB has just decided to install a new e-mail package. One vendor is offering SMTP-based two-tier client-server architecture. The second vendor is offering Web-based e-mail architecture. Fred doesn’t understand either one but thinks the Web-based one should be better because, in his words, “the Web is the future.” a. Briefly explain to Fred, in layperson’s terms, the differences between the two. b. Outline the pros and cons of the two alternatives and make a recommendation to Fred about which is better. How E-mail Works The Simple Mail Transfer Protocol (SMTP) is the most commonly used e-mail standard simply because it is the e-mail standard used on the Internet. E-mail works similarly to how the Web works, but it is a bit more complex. SMTP e-mail is usually implemented as a two-tier thick client-server application, but not always. Two-Tier Thick E-mail Architecture With two-tier thick client-server architecture, each client computer runs an application layer software package called a mail user agent, which is usually more commonly called an e-mail client (Figure 1). There are many common e-mail client software packages such as Eudora and Outlook. The user creates the...

The first alternative in terms of application architecture is a client-based architecture. As it states that the downloaded tool will communicate with the DRUB server to select data and analyze, which is very similar to the client-based architecture where the clients tells the server what data to select and analyze and processes data will be sent back to the client for display. The second alternative in terms of application architecture is two-tier client-server architecture. The application logic can be partitioned between the client and the server. The server is responsible for the data and the client, the application and presentation. Using the web browser the client will talk to the web server using a standard called HTTP (Jerry Fitzgerald, 2009). b.
