...Copyright © 2004 Information Systems Audit and Control Association. All rights reserved. www.isaca.org. How to Use a New Computer Audit Fraud Prevention and Detection Tool By Richard B. Lanza, CPA, PMP W hile occupational fraud takes various forms, the result is always the same: the numbers generated by fraud cannot hold up to the unfailing logic of the accounting equation. If executives add false sales and accounts receivable to increase the organization’s revenue, profits and cash will be out of kilter. The advancement of technology has allowed for this “accounting equation” to be systematized into computer logic and applied to company data.1 Results of this logic could take the form of a simple matching of the human resource file to the accounts payable vendor master file. On the other side of the coin, it could be an advanced neural network application focused on detecting money laundering schemes. Whether it is simple or advanced, data analysis provides many benefits in the prevention and detection of fraud. On one hand, the fraud examiner gains insight on 100 percent of an organization’s transaction data vs. more limited manual methods of selection. Further, this approach can generally be completed in less time than manual procedures, given the automation of the work. Examiners also gain improved business intelligence as the generated reports often lead to conclusions beyond whether just fraud occurred. Such new insights can lead to suggested process improvements...

Let’s start in the year 1939 where David Packard and Bill Hewlett first started there company there first product was called the HP 200A Audio Oscillator which was a popular piece of test equipment for the engineers Walt Disney Pictures was their first customer and ordered eight of the 200B model to use as sound effects generators for the movie “Fantasia” in the 1940s the first (CNC) that was build was call “The Complex Number Calculator” designed by researcher George Stibitz and demonstrated in New York at the Dartmouth College. This demonstration showed that this was to consider to be the first remote access computing using a teletype connected via special telephone lines through this timeline.( 2006 Computer History Museum) it will show that from the moment Computers was thought of and how the build went through a concept of steps before fully calling a (PC) an Personal Computer a lot of what I have read and seen through the timeline of the history of are computers for every new year a new chapter starts in building a fully functional computer but over time is where it took for where it all began as different components that different Engineers build.

...interact with computers and the internet. Although this is a good thing for me, it doesn’t blind me to the fact that there are some people who just don’t understand the concepts of a computer and the internet. The "computer generation" is not just for one generation. The elderly don't have to sit back and watch while the younger generations have fun banking, playing, shopping and socializing online. But many elderly people shy away from computers out of fear, wondering "What if I break it?" or "What if someone steals all my personal information?" The concern over the growing “digital divide” has led to a number of initiatives being employed to encourage web usage for the older generations, and to ensure they are not excluded from the digital world. Among these is educating the elderly on ways computers may benefit their lives. Some computer manufacturers have designed computers especially for elderly users. The designs acknowledge seniors' limitations on a computer, attempting to make a comfortable user for them. For instance, the designs tend to emphasize simplicity and straightforward commands and prompts. Keyboards are less cluttered with keys, and the software lacks design complications. The computers also make the tasks common to elderly users, such as email or viewing photos, easy to access and operate. These are just a few ways companies as well as new technology make it easier for the elderly to learn. Among the complications for the elderly in using computers are the...

...Accountability and Ethics Computer Addiction and Cyber Crime Nick Nykodym The University of Toledo Sonny Ariss The University of Toledo Katarina Kurtz The University of Toledo This research explores the relationship between computer addiction and cyber crime. There is evidence of computer addiction in medical settings, scholarly journals and legal proceedings. Reviewing the history of computer addiction has shown that computer addiction can be related to cyber crime. This paper will define computer addiction, show how various cyber crimes, especially those against businesses and organizations, can be motivated by computer addiction and propose further research on how managers can deal with cyber crime in a business, by recognizing addictive behaviors and computer addiction in their employees. HISTORY OF COMPUTER ADDICTION Computer addiction is an idea that has been in existence for years. Since the 1970s, avid computer programmers and hackers have been called “addicts” by both psychologists and the general public (Reed, 2002, p. 135). In 1976, Weizenbaum wrote about computer programmers who could sit and work at their computer terminals for twenty or thirty hours at a time. This behavior however, was viewed at the time as useful to technology and society. Computers, once seen as huge government machines that only very knowledgeable people could use, transformed into user-friendly tools that could be used by the everyday person. It became more common to see computers in homes and businesses...

...1 Teachers’ Views of Computers as Catalysts for Changes in Their Teaching Practice Sara L. Dexter and Ronald E. Anderson University of Minnesota Henry Jay Becker University of California, Irvine This paper was published in the Journal of Research on Computing in Education. The citation for it is: Dexter, S., Anderson, R. E., & Becker, H. J. (1999). Teachers’ views of computers as catalysts for changes in their teaching practice. Journal of Research on Computing in Education, 31 (3), 221239. Abstract: In this study we examined the use of computers by teachers in their instructional practices and their perception of the impact of computers on changes they have made to their classroom practice. These data draw from 47 teachers from 20 K-12 schools across 3 states who each completed a questionnaire, participated in 3 semi-structured interviews, and allowed 3 observations of their classroom. The teachers who had adopted more progressive teaching practices over time felt computers helped them change but they did not acknowledge computers as the catalyst for change. Instead, they cited catalysts that included: reflection upon experience, classes taken, and the context or culture of the school. We conclude that in order for teachers to implement the use of educational technology in a constructivist manner, they must have opportunities to construct pedagogical knowledge in a supportive climate. Research funded by the program of Research on Education Policy and Practice at the National...

Introduction The world we live in today is very different from what it was a century, even a few decades ago. This transformation has been driven in part by rapid technological innovation. While the 19th century saw the rise of the Industrial Revolution, with steampowered machines intensifying and expanding human productive power, the 20th century was characterized by the birth of machine-powered flight and the emergence of broadcasting and computer technologies that extended the reach of human creativity even more and made possible new ways by which humans could live and work together. In the past fifty years, especially, technology has made information, once a scarce resource, abundant. With computers and Internet technologies in particular, more people can now have access to more information more quickly than ever before. Moreover, the...

...today computers are vastly changing the way we do things and how jobs are run. Computers up grade things that at times make things more efficiently ran, and at times cut down on the time it takes to do a project. It changes the way we do things and makes things easier to understand with some work fields that people are in today. With some fields of work computers would not really help out that much but in my field it helps out a lot. Just from the tools that we use it is mostly a computer base thing. My major is Recreation Management. So it is basically and outdoor type of major that deals with things like forest, agriculture, animals, and the land in general. So from the classes I have this year I am learning that computers are vastly becoming a part of my major. We use things like Geo II Explorer, and the Garmin E-Trex. Those to are computer-based object that you need to up load and transfer your data to and from the computer. The Geo II Explorer with creates maps and plots the points of where you have been and how to get to one point to another. It is all ran off satellite information that you get signaled back to your receiver. Then the Garmin E-Trex with give you directions to and from places let you plot points of where you have been and store them right on it in a little hard drive that is installed in it. These two tools are what are mostly used for the field that I am going into. I will be outside most of the time for mine so I defiantly need to know how to use these...

...citizens with the digital technology. What this new program we will be able to allow senior citizens to be educated on computer use and digital use of technology. This will allow them freedom to know how to use the internet properly and how to access healthcare providers using the Internet. Some sentences are well equipped with using the Internet and computers. I like that we use some of our own senior citizens that they are comfortable with using the internet to teach the other senior citizens with less confidence how to use it. This is beneficial on a health tip because as I will see you soon and get older they feel as if they have less freedom to do things and things are too complicated for them to learn now. However, by teaching them how to use the Internet and computers this opens up a nether door for I retired senior citizens and for some of our senior citizens without families this will give they time to spend with other senior citizens and learning new skills. Which of this program computer classes for senior citizens offering dramatic stimulation and relative technology education? Other seniors will tell classes so it will be on a related basis computer classes for senior citizens range from very simple intermediate to advanced training course.
