Solution of Chapter 1

1.1 In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems.
a. What are two such problems?
b. Can we ensure the same degree of security in a time-shared machine as in a dedicated machine? Explain your answer.
Answer:
a. Stealing or copying one’s programs or data; using system resources (CPU, memory, disk space, peripherals) without proper accounting.
b. Probably not, since any protection scheme devised by humans can inevitably be broken by a human, and the more complex the scheme, the more difficult it is to feel confident of its correct implementation.
1.2 The issue of resource utilization shows up in different forms in different types of operating systems. List what resources must be managed carefully in the following settings:
a. Mainframe or minicomputer systems
b. Workstations connected to servers
c. Handheld computers
Answer:
a. Mainframes: memory and CPU resources, storage, network bandwidth.
b. Workstations: memory and CPU resources
c. Handheld computers: power consumption, memory resources.
1.3 Under what circumstances would a user be better off using a timesharing system rather than a PC or single-user workstation?
Answer: When there are few other users, the task is large, and the hardware is fast, time-sharing makes sense. The full power of the system can be brought to bear on the user’s problem. The problem can be solved faster than on a personal computer. Another case occurs when lots of other users need resources at the same time.
A personal computer is best when the job is small enough to be executed reasonably on it and when performance is sufficient to execute the program to the user’s satisfaction.
1.4 Which of the functionalities listed below need to be supported by the operating system for the following two

...Chapter 1 27. If they get married in 2010 and file jointly they will pay $38,643.50 [(10% x $16,750) + (15% x $51,250) + (25% x $69,300) + (28% x $42,700)]. If they wait until 2011 to get married and Conrad files as a single individual he will pay $44,516.75 [(10% x $8,375) + (15% x $25,625) + (25% x $48,400) + (28% x $89,450) + (33% x $8,150)]. It would be to their advantage to marry before the end of 2010 because they would save $5,873.25 in income taxes. If they each made $90,000 and both filed individually, they would pay in a combined total of $37,818.50 = 2 x $18,909.25 [(10% x $8,375) + (15% x $25,625) + (25% x $48,400) + (28% x $7,600)]. In this case, it would make more sense to wait until 2011 to get married and each file individually in 2010 because it will save them an additional $825. It would make no difference if they got married in 2010 and filed jointly or separately $38,643.50 = 2 x $19,321.75 [(10% x $8,375) + (15% x $25,625) + (25% x $34,650) + (28% x $21,350)]. 28.

This illustrates vertical equity as well as a progressive tax system where each tax bracket pays a different percentage of their income in taxes – the more money you earn, the higher your tax rate; and, just because you earn twice as much as someone else, it...

Net benefits are N (Q ) = 50 + 20Q − 5Q 2 . b. Net benefits when Q = 1 are N (1) = 50 + 20 − 5 = 65 and when Q = 5 they are N (5) = 50 + 20(5) − 5(5) = 25 . Marginal net benefits are MNB (Q ) = 20 − 10Q . Marginal net benefits when Q = 1 are MNB (1) = 20 − 10(1) = 10 and when Q = 5 they are MNB (5) = 20 − 10(5) = −30 . Setting MNB(Q ) = 20 − 10Q = 0 and solving for Q , we see that net benefits are maximized when Q = 2 . When net benefits are maximized at Q = 2 , marginal net benefits are zero.

...Chapter 1 Review Questions Solutions 1. What is information systems analysis and design? Information systems analysis and design is the process of developing and maintaining an information system. 2. What is systems thinking? How is it useful for thinking about computer-based information systems? Systems thinking involves identifying something as a system, visualizing the system and translating it into abstract terms, and thinking about the characteristics of the specific situation. Systems thinking is useful for thinking about computer-based information systems because information systems can be seen as subsystems in larger organizational systems, taking input from, and returning output to, their organizational environments. 3. What is decomposition? Coupling? Cohesion? Decomposition is the process of breaking down a system into its component parts. Coupling is the extent to which subsystems are dependent on each other. Cohesion is the extent to which a system or a subsystem performs a single function. 4. In what way are organizations systems? Organizations are systems because they are made up of interrelated components working together for a purpose. They take input from and return output to their environments. Organizations can be redesigned through a systems analysis and design process by which system components are replaced while preserving interconnections between components. 5. List and explain the different phases in the systems development...

(b) artificial intelligence – the ability of a computer or robot to act like a human and make decisions based on pre-defined rules. (c) agent – is the entity that is doing the actions, it can interact with the environment, change it, and learn from it. (d) rationality – is the ability of doing the right thing based on what it already knows or has learned from the environment. (e) logical reasoning – is the process using arguments, statements, premises, and axioms to determine whether a statement is true or false. 1.3 - Yes, reflex actions such as flinching from a hot stove are rational because it is the right thing to do. We don’t think before we flinch from a hot stove because it suppose to be quick, thinking will defeat the purpose of flinching. - No, I believe that reflex actions are not intelligent because you don’t have to put any thought into them, we do them automatically. 1.4 No, the program wouldn’t be more intelligent than a human because the artificial intelligence systems will avoid trying to solve problems.

Options and Derivatives Chapter 1 Solutions

...CHAPTER 1 Introduction Practice Questions Problem 1.1 What is the difference between a long forward position and a short forward position? When a trader enters into a long forward contract, she is agreeing to buy the underlying asset for a certain price at a certain time in the future. When a trader enters into a short forward contract, she is agreeing to sell the underlying asset for a certain price at a certain time in the future. Problem 1.2. Explain carefully the difference between hedging, speculation, and arbitrage. A trader is hedging when she has an exposure to the price of an asset and takes a position in a derivative to offset the exposure. In a speculation the trader has no exposure to offset. She is betting on the future movements in the price of the asset. Arbitrage involves taking a position in two or more different markets to lock in a profit. Problem 1.3.

Chapter 1 Hw Solution - Tax

...Chapter 1 Taxes and Taxing Jurisdictions Questions and Problems for Discussion 1. Tax payments differ from government fines and penalties because they are not intended to deter or punish unacceptable behavior. Tax payments differ from fees or user charges because they do not entitle the payer to a specific government good or service, such as a postage stamp or a driver’s license. Tax payments also differ from fees or user charges because they are compulsory. 2. This payment has characteristics of a tax, a penalty, and a user fee. The compulsory payment is not specifically punitive but does apply selectively to those companies most likely responsible for the polluted condition of Green River. However, these same companies may be the entities that benefit most from the environmental clean-up. 3. This payment more closely resembles a fee for a government service than a transaction-based tax because the transaction occurs between a private party and the jurisdiction itself, rather than between private parties engaging in a market transaction. The payment also entitles the payer to a specific benefit (the right to marry under law). 4. To the extent that the decline in exterior maintenance reduces the value of Mr. P’s apartment complex, he bears the incidence of the increased property tax.

Capital budgeting (deciding whether to expand a manufacturing plant), capital structure (deciding whether to issue new equity and use the proceeds to retire outstanding debt), and working capital management (modifying the firm’s credit collection policy with its customers). Disadvantages: unlimited liability, limited life, difficulty in transferring ownership, hard to raise capital funds. Some advantages: simpler, less regulation, the owners are also the managers, sometimes personal tax rates are better than corporate tax rates. The primary disadvantage of the corporate form is the double taxation to shareholders of distributed earnings and dividends. Some advantages include: limited liability, ease of transferability, ability to raise capital, and unlimited life. The treasurer’s office and the controller’s office are the two primary organizational groups that report directly to the chief financial officer.

The Government and Not-for-Profit Environment Chapter 1 Solution Manual

...Chapter 1 The Government and Not-For-Profit Environment ------------------------------------------------- Questions for Review and Discussion 1. The critical distinction between for-profit businesses and not-for-profits including governments is that businesses have profit as their main motive whereas the others have service. A primary purpose of financial reporting is to report on an entity’s accomplishments — how well it achieved its objectives. Accordingly, the financial statements of businesses measure profitability, their key objective. Financial reports of governments and other not-for-profits should not focus on profitability, since it is not a relevant objective. Ideally, therefore, they should focus on other performance objectives, such as how well the organizations met their service goals. In reality, however, the goal of reporting on how well they have achieved such goals has proven difficult to attain and the financial reports have focused mainly on financially-related data. 2. Governments and not-for-profits are “governed” by the budget, whereas businesses are governed by the marketplace. The budget is the key political and fiscal document of governments and not-for-profits. It determines how an entity obtains its resources and how it allocates them. It encapsulates most key decisions of consequence made by the organization. In a government the budget is not merely a managerial document; it is the law. 3. Owing to the significance of the budget...
