...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......

...Running head: COMPUTER CRIME 1 Computer Crime and the 4th Amendment ITT Technical Institute COMPUTER CRIME 2 The case law that would allow me to search the office computer of Jacob Myers would be the 4th Amendment law and also The Wire and Electronic Communications Interception and Interception of Oral Communications Act. Under the 4th Amendment to do a search and seizure you need to have probable cause. Under The Wire and Electronic Communications Interception and Interception of Oral Communications Act it typically requires a court order issued by a judge who must decide that there is probable cause to believe that a crime has been, is being or is about to be committed. In this case we do have probable cause because the victim, Cynthia Simmons had to countless number of times change her email, IM, and internet provider; during a preliminary investigation we scanned the victims computer and found a key logging program was being used to collect the victims information and stalk the victim. And upon our investigation, posing as the victim the offender once again sent the victim a message via IM. That conversation allowed the officers to trace the computer to the offender’s job at the probation department. So because the suspect Jacob Myers works at the probation department and he has been the one previously stalking the victim there is enough probable cause to search his work computer and put surveillance because now he......

...What is Computer : Computer is an electronic device that is designed to work with Information.The term computer is derived from the Latin term ‘computare’, this means to calculate.Computer can not do anything without a Program.it represents the decimal numbers through a string of binary digits. The Word 'Computer'usually refers to the Center Processor Unit plus Internal memory. Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.The basic components of a modern digital computer are: Input Device,Output Device,Central Processor. A Typical modern computer uses LSI Chips. Charles Babbage is called the "Grand Father" of the computer.The First mechanical computer designed by charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards. Four Functions about computer are: accepts data | Input | processes data | Processing | produces output | Output | stores results | Storage | Input (Data): Input is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc. Process: Process is the operation of data as per given instruction. It is totally internal process of the computer system. Output:......

...The computer is one of the most brilliant gifts of science. This device was originally developed by Charles Babbage. Most countries have developed fast due to computerization. Writing a program is essential for a computer. Speed, accuracy, reliability, and integrity are the main characteristics of a computer. Many of the routine activities today at home and in business are done by computers. The computer has proved a friend and servant of science, technology and industry. Most offices, shops, factories and industries use computers. The Internet is a storehouse of information. The computer is a boon to all. Telecommunication and satellite imageries are computer based. Computers have made the world a global village today. The computer is one of the most brilliant gifts of science. It is an electronic device for storing and analyzing information fed into it, for calculating, or for controlling machinery automatically. Charles Babbage developed this device first in 1812 followed by George Boole in 1854, Howard and Aitten in 1937, Dr. John Nouchly and J. P. Eckert in 1946. These computers were named the first generation equipment. Today, wit the 'Artificial Intelligence' technology, we are using fifth generation computers. Each new generation of computers has been smaller, lighter, speedier and more powerful than the earlier ones. Now note-book sized computers like laptop are fairly common. Computers have been dominating technology since 1970s, and has now entered almost all......

...this point I think it is also can link to the knowledge retention. In an organization, much of vital knowledge can be held by single people. A single subject matter expert may hold vital operational knowledge in his or her head, representing a “single point of failure” for the organization. (In here, we can say this is the 20% of employees produce 80% of a company's results.) If the person leaves, they are older, and they are reaching retirement age. This is a kind of knowledge loss, means when valuable knowledge is no longer available for the organization to use. We want to eliminate the knowledge loss we need to understand the knowledge retention. Knowledge retention in the context of losing key employees and using techniques such as exit interviews to try to capture their knowledge. In reality, knowledge retention should be integrated into how the organization operates and start well before a key employee is about to depart. Although it is considered crucial for long term organizational success, few organizations have formal knowledge retention strategies (Liebowitz 2011). A knowledge retention strategy as a part of knowledge management (KM) will identify the knowledge resources that are at risk and must be retained, and then implement specific initiatives so as to keep these resources in the firm. Like most other KM-related processes and strategies, success depends upon successful knowledge sharing and having a knowledge sharing & learning organizational culture.......

...The computers process information's that come in all shapes and sizes from any fields so accurately that, some people may call these "Informatics"— The Science of Informal ion Processing, i.e. the methods of recording, manipulating and retrieving information's. It may be from a mathematical equation to a company's work-force necessary to produce a payroll or from meteorological department to forecast tomorrow's weather or from space research to project a new space craft. The following characteristics that make the computers very popular for its multifarious uses may give the befitting reply. Speed First, the computers are regarded as high speed calculators. They can process voluminous data within a fraction of second which no human being could do earlier. If we want tomorrow's forecast today, meteorologists can use the computers for necessary calculations and analyses. The units of speed of a computer are the microsecond, the nano (10)-9 second and even the picot second. Storage As human brain can store the knowledge in memory and can able to recall it, the Central Processing Unit (CPU) of a computer can do the same job without any failure. But the internal memory of CPU is only large enough to retain a certain amount of information. So, to store each and every information inside the computer, an Auxiliary or Secondary Storage Device is being attached outside the memory of the CPU. Accuracy The computers are much popular due to their high speed along with......

...Computers, of course, can play a helpful role in an educational system of self-reliant independent learners. Over the next 20 years computers will significantly supplement books as a source of information. Computers will supplement teachers as a source of instruction, testing, and feedback. Computers will become individual tools, as pencil and paper are today, to aid in the learning and problem solving process. But the student as self-reliant and as an independent learner is not dependent on computers, and progress towards such goals can occur in the absence of computers. Thus, each reader of this essay can help to improve education. If you are a parent, interact with your children to help them become more self-reliant and independent learners. If you are an educator, stress this idea when working with students and other educators. And don't forget to do the same thing for yourself. If you feel the need to learn more about computers or some other topic, decide for yourself what you want to learn, why and how. Set your own standards for measuring whether you have gained the skills and knowledge you seek. For me a clear picture emerges from the type of analysis given above. The educational environment can be improved, and educational goals and requirements can be changed. Computers will play an increasing role as change agent as well as within the curriculum. But far bigger improvements are possible if we can help students to take increased responsibility for their own......

...ages before, when there were no computers or any other technologies. So much we have advanced that now every information is just a click away and is in your hands 24/7. All this advancement was possible only with the introduction of a small device called the “Computer”. Computers Image Curtsey: csntrust.org.nz/attachments/Image/PC-picture-1.jpg?1367216528141 Basically, computer is a device that accepts the message by the imputer and processes this message and stores the information at the storage devices and later gives an output of the message through the output devices. A simple explanation of the computer. Normally, a computer consists of a processing unit called the Central Processing Unit or the CPU and a form of memory. In the years between 1940 and 1945 were the first electronic digital computers developed. The initial sizes were as big as a room and consumed power as much as today’s personal computers. Initially, computer was related to a person who carries out calculations or computations and as such the word computer was evolved in 1613 and continued till the end of 19th century. Later it as re-described as a machine that carries computations. The early computers were limited in their functions. It was the fusion of automatic calculation and programmability that produced the first computers that were recognized in 1837. Charles Babbage in 1837 was the first to introduce and design a fully programmed mechanical computer, his analytical engine. Due to......

...An individual that is computer literate has many advantages in life. All high-paying jobs require its employee to be computer literate. This skill is a must in order to be successful in the workforce. Computers have become a part of our everyday lives. Life would be very difficult without them. I am very computer literate. Working on computers became a hobby of mines back in high school. Operating on one is not an easy task if one has no idea of what he or she is doing. I started out make many mistakes on computers before I became an expert at them. For example, my grandmother bought me a computer for Christmas and I was the happiest kid in the candy store. I immediately went to the games section and enjoyed them to the fullest. One day, I began to run low on disk space and decided to go into my system files and delete random files and folders that I thought were useless to the computer. Sure enough they were useless until my computer displayed symbols and signs where text should have been. It was as if my computer exhibited a different language but only through different shapes and signs. I was terrified that I had done this to my computer! My mom later called customer service to resolve the problem, but never again did I go into my system and delete random files unless I knew exactly what I was deleting! I’ve learned a lot from my mistakes on working with computers. I am now a pro in the field of computers. I’ve had clients in the past that I have......
