How to Analyze the Life Cycle Steps for an Information System
How to Analyze the Life Cycle Steps for an Information System Explain the life cycle of an information systems. Apply the steps of the life cycle to the scenario listed below: Imagine that you run a photography printing store. Your employees have been using punch cards for time entry since you started the business. This has lead to many problems including lost cards, inaccurate hours, and employees punching in other employees. Because of these problems you are considering implementing a computerized time entry system. Describe each step of the life cycle, and apply it to your problem in your business.
False Assurance and ATO fraud case-Accounting
SIT202 Computer Networks
Question 1 (Week 7) (14 marks)
Working for a software company you are attending a meeting to discuss the development of a
new application which will allow massive volumes of data to be transferred over several days.
One of the topics for discussion is whether the TCP or UDP protocol should be used. One of your
colleagues is convinced that TCP must be used as it provides services such as error control and
flow control which are critical for the data delivery task. Another colleague however points out
that the requirement for data transfer to occur over several days mandates the use of UDP, as
even a temporary network outage could cause the TCP connection to be dropped, in turn causing
the transfer to be aborted. In response, you tell them that they’re both wrong, and that either
protocol could be used. For both TCP and UDP:
i. Briefly explain how the protocol could successfully be used for this application;
ii. Briefly explain two advantages and two disadvantages of using the protocol for this
application.
Question 2 (Week 8) (17 marks)
Consider the operation of the SMTP protocol as illustrated in Week 8 Slide 59:
i. Briefly describe what is happening at each step of this exchange
ii. Briefly describe three services of the underlying transport layer and how they are
used/exploited by this application protocol.
iii. Briefly explain why this particular style of message exchanges and the formatting of the
email data section have been chosen for this application protocol.
Question 3 (Week 9) (16 marks)
Consider the Management Information Base proposed/defined for the TCP protocol in RFC4022:
https://tools.ietf.org/html/rfc4022
Briefly discuss what information you could learn about your network from the following objects:
• tcpAttemptFails
• tcpEstabResets
• tcpRetransSegs
• tcpConnectionTable
For each of the objects identified above:
i. Briefly describe what information the object contains (must be in your own words)
ii. Discuss what can be learned about what’s happening in the network on the basis of this
information, e.g., what would a low value versus a high value in object X potentially mean
is happening on the network?
Question 4 (Week 7-9 Prac) (9 + 4 + 6 = 19 marks)
a) Demonstrate the use of sequence numbers and acknowledgement numbers by the TCP
protocol to send a random short phrase which is divided into three segments, two of which
are delivered and acknowledged, before the final segment is delivered and acknowledged.
Note that only segment data content, sequence number, and acknowledgement numbers
are required.
Hint 1: Running a Google search for “short quotes” or similar will result in many short
phrases that could potentially be used (remember Code of Conduct rules apply, nothing
offensive/ abusive can be used).
Hint 2: A figure such as those prepared for Problem Solving Report 2 could help you to
answer this question!
b) In the Week 8 lab task, we examined the behaviour of the DNS protocol. Identify what
layer of the TCP/IP model the DNS protocol runs at and explain why.
c) In the Week 9 practical we examined the SNMP protocol (addressed in Question 3) and the
NetFlow protocols. Briefly describe what kind of information is provided by the NetFlow
protocol and briefly discuss what this information could be used for.

Case Study – Analyze the Verizon Vodafone
Analyze the Verizon Vodafone sale from Vodafone’s perspective. Specifically analyze how this transaction fits Vodafone’s Global Strategy. Address how this transaction is judged via the CAGE perspective. Does it fit the Better-Off and Best Alternative tests? How should have consideration of the AAA Strategies (Aggregation, Adaptation and Arbitrage) affected the thinking of Vodafone executives while pondering this sale? How does sizeism factor in this sale? Demonstrate if and how the disposition of Verizon Wireless fits into Vodafone’s strategic plan. Finally, in your judgment was this a good deal for Vodafone-why or why not and will Vodafone regret this sale? Vodafone In two decades, Vodafone became the telecommunications leader in Global Systems for Mobile networks (www.associatedcontent.com). Vodafone provides innovative and cutting edge telecommunications services on the largest wireless network on earth. In this article, I will discuss how Vodafone was started and the growth of one of the world’s largest company. Vodafone was formed in 1983 as a joint venture between Rascal Electronics (a UK electronic firm) and Millicom (a US telecom company), and was granted one of two mobile phone licenses in the UK (www.associatedcontent.com). That became the UK’s first mobile license. The name Vodafone came from the firm’s goal to establish a voice and data services over cellular telecommunication networks. In which, the VO is represents voice and the DA symbolizes data, hence Vodafone (www.associatedcontent.com). In 1985, Vodafone launched its service but as a Rascal subsidiary (www.vodafone.com). October of 1987, Vodafone launched Vodapage. Which, is a paging network covering over 80% of the country (www.vodafone.com). In 1988, Rascal offered 20% of Vodafone to the public and would become Vodafone Group (www.associatedcontent.com). The beginning of the 1990s, Vodafone moves beyond the UK. In 1990, Vodafone customer base reaches 500,000 (www.vodafone.com). In October of 1992, Vodafone begins Commercial services. Vodafone was the first Portuguese company to offer a Customer Care Service available twenty-four hours a day and seven days a week (www.vodafone.com). Also, in 1992 Vodafone was named Company of the Year at Business Enterprise Awards (www.vodafone.com). By 1993, Vodafone’s international reach extends, with licenses and partnerships in Germany, South Africa, Fiji, Australia, and Greece (www.vodafone.com). Vodafone started networks for mobile phones in these other countries. Their strategy was to acquire competitors in order to knock out competition and become more competitive than its rivals (www.associatedcontent.com). March of 1994, Vodafone joins up with the Globalstar consortium to develop and launch low orbit satellite capability to supplement land-network coverage (www.vodafone.com). Also, in November of the same year Vodafone launches digital data fax and SMS (Short text messaging) service (www.vodafone.com). In 1995, Vodafone kept expanding in the Netherlands, Uganda, Hong Kong, and France (www.vodafone.com). November 1997, Vodafone launch of their digital Pay As You Talk’ pre-paid service for their frequent users (www.vodafone.com). In 1998, Vodafone is the first Portuguese mobile operator offering and introducing mobile phone in the market offering both bounds, 900 MHz and 1800 MHz (www.vodafone.com). Vodafone reaches service revenues of 0.5 EUR billion (www.vodafone.com). In 1999, Vodafone becomes both Internet Service Provider (ISP) and a content provider in Portugal (www.vodafone.com). Vodafone made two of the most landmark acquisitions that were those of D2 (Mannesmann; Germany) and Airtouch (US) (www.associatedcontent.com). D2 was one of the leading telecommunications providers in Germany. The Mannesmann takeover was hostile, and the first of its kind in Europe; this was the largest “unwanted” acquisition of its time (www.associatedcontents.com). The transaction was valued at $180 billion dollars (www.associatedcontent.com). The second acquisition was that of Airtouch communications in the United States (www.associatedcontent.com). Which now is called Vodafone Group Plc; this gave Vodafone its entry into US market and the ability to consolidate minority interest in European carriers (www.associatedcontent.com). The transaction was worth $60 billion dollars (www.associatedcontent.com). In May 2000, Vodafone launches Verizon Wireless (www.vodafone.com). Vodafone and Bell Atlantic combined their US wireless assets to make up Verizon Wireless (www.vodafone.com). Vodafone launches YORN (Young Original Network), first global and integrated communications network, a brand new concept of content initiatives, events and offerings for the younger generation (www.vodafone.com). To further their strategy in 2001, Vodafone completed a deal to acquire Ericell in Ireland, which is now Vodafone Ireland (www.associatedcontent.com). Then, Vodafone signed a strategic alliance agreement with China Mobile based out of Hong Kong (www.vodafone.com). Vodafone unleashed the first global communication campaign in August of 2001. The campaign features TV, cinema, print, online and outdoor media (www.vodafone.com). In 2002, Vodafone gave trial of their global mobile payment system in the UK, Italy, and Germany. The trial enables customers to purchase physical and digital goods using their mobile phone (www.associatedcontent.com). In October 2002, Vodafone announced the launch of “Vodafone live!” a fully innovative concept in the integration of services and content in mobile communications (www.vodafone.com). It would provide a new consumer proposition, Mobile Office, and a new business proposition (www.vodafone.com). Also, in November 2002, launches a Vodafone Remote Access, which is a part of the mobile office. This service would give business customers an easy way to connect to their corporate LAN to access e-mail, calendar and other business specific applications while on the move (www.vodafone.com). Vodafone in 2003 allows football fans to watch, for the first time in Portugal, an entire football match as it happens on the small screens of mobile phones through “Vodafone live!” (www.vodafone.com). In the first six months of the launch of “Vodafone live!” it attracts one million customers (www.vodafone.com). Also, at the GSM (Global Systems for Mobile Networks) Association Awards Ceremony in Cannes, France, Vodafone won the mobile industries most prestigious awards I two categories, best consumer wireless application or service and best television or broadcast commercial for its global consumer service, “Vodafone live!” (www.associatedcontent.com).

Economics
Use the Quantity Equation for this problem. Suppose the money supply is $200, real output is 1,000 units and the price per unit of output is $1. Calculate the velocity of money? Answer: Assuming money neutrality, if the velocity is constant at the value you solved in part (a), what does the quantity equation suggest will happen if the money supply is increased to $400? Answer: Consider your answer to part (b). Would your answer be different if the short-run rather than the long-run is considered? Explain (i.e. Money neutrality no longer applies) Answer: Now suppose that the money supply is growing at 8 percent per annum and real GDP is growing at 4.6 percent per annum. What is the inflation rate? (Assuming velocity remains constant) Answer: Question 4 Using the Aggregate Demand and Aggregate Supply (AD-AS) diagram in the short-run,illustrate what will happen to Singapore’s aggregate demand and/or aggregate supply under each of the following situations.State how this will affect the inflation rate and the unemployment rate. The US and other trading partners adopt protectionist trade policies, increasing taxes and tariffs on all imported goods and services. Answer: The government reduces business taxes for all companies operating in Singapore.
All public agencies receive a program evaluation
All public agencies receive a program evaluation, which is an external examination of a program’s overall effectiveness. A program evaluation may use a variety of administrative and organizational data (e.g., statistics) to assess whether the program objectives are being met and how well the program is serving its customers. A program evaluation can face some difficulties because multiple agencies may be involved in the program, along with often conflicting and changing program objectives. You are to develop a six- to eight-page paper that evaluates an existing governmental program during a year’s cycle of that program.eight-page paper that evaluates an existing governmental program during a year’s cycle of that program. Focus of thePaper Choose any governmental (federal, state, or local) program (Social Security Administration, Department of Defense, Federal Aviation Administration, Department of Motor Vehicles, City Hall, etc.) to evaluate. Your evaluation of this public agency should focus on three primary areas: Financial Compliance: Assess whether the agency’s funds were properly spent in compliance with the agency’s budgetary authorization law(s) and/or with any relevant compliance regulations. Efficiency: Evaluate whether the public agency used its allocated resources (i.e. financial, human) efficiently to achieve optimum productivity. Program Effectiveness: Appraise the public agency’s effectiveness in achieving two of its organizational purposes and/or goals. This project will require you to research information related to your governmental agency, so you may want to cursory review of the agency before beginning your project to ensure you can readily identify the necessary information. Some of the information may not be easily recognizable as you may not be familiar with the agency. The Paper: Must be six to eight pages in length (not including the title and in length Must include an introductory paragraph with a succinct thesis statement. Must address the topic of the paper with critical thought. Must conclude with a restatement of the thesis and a conclusion paragraph. Must use at least five scholarly sources in addition to the text– (Shafritz, J.M., Russell, E.W. & Borick, C.P. (2013). Introducing public administration (8th ed.).

The economics of labor
Question 9. The following two unrelated questions, 9A and 9B pertain to the economics of labor: Question 9A. In the past 20 years, union leaders have been organizing drives to sign up employees of state and local government agencies (police, firefighters, prison guards, etc…) as well as services workers (custodians, hotel and restaurant workers, etc…). During the same period, union efforts to organize the manufacturing sector have notmet the same level of success as they have in the public services sector. · Can you explain why unions are less successful in organizing the manufacturing industry but more successful with these public agencies and services sector? Question 9B. When the Washington State legislature was debating a Bill in 2001 that would allow optometrists to administer certain eye-drops during eye exams, 50 ophthalmologists descended on the state Capitol to lobby against the Bill. The chairman of the state Academy of Ophthalmology told a reporter: “There is no economic advantage one way or the other.” The ophthalmologists’ sole concern was that, if the Bill became law, “more people will be harmed through inappropriate use of drugs.” (Note: optometrists are not medical doctors, and their training focuses on examining the eye for defects and faults and prescribing correctional lenses). · Do you believe that 50 medical specialists all took a day off from their practices to lobby the legislature exclusively out of concern for the public’s health? Use the demand and supply to show what the medical doctors are trying to achieve by defeating the bill.
