Provide a brief description of each component. 1. Processor (CPU): The processor is the brain of the computer and is the chip where all the computing is done. 2. Memory: This is where the computer stores information while it is working on it. 3. Chipset: The chipset is a link between the processor and the outside world, and handles things like controlling the hard drives, the USB ports, the keyboard and mouse, generates the sounds the computer makes, and sometimes even creates the pictures you see on the screen. 4. Expansion Slots: Expansion slots are connectors that allow you to attach additional cards on the computer, such as video cards, sound cards, modems, and add abilities to the computer that the motherboard doesn’t provide. 5. I/O (Inputs/ Outputs): These are a set of connectors that allows you to connect various devices to the computer, such as the keyboard, monitor, mouse, hard drives, flash drives, printers, and connect the computer to a network. 2.

...Arguments about Computer dependency Since their invention, people far and wide have become increasingly dependent on computers. Computers have found their way into just about every aspect of our lives, and in most cases, they make things easier for us [4] . They allow us to work from home, socialize with our friends and family who live too far away to visit, and they provide an ever-welcome stress relief when we come home from school or work and just want to have some fun. But as we increasingly rely on computers to get through the day, the question begs to be asked: have we become too dependent on computers? Despite the many benefits of computers, there are also a number of arguments against them, one of which is the negative effect some believe they are having on children's education. Illiteracy is a growing issue, and many say that computers are to blame. In the past few years, many teachers have taken to shuffling their students off to a computer to type out short, quick assignments that could easily be written out by hand. While this isn't much of an issue for older students, it is an issue for the younger students who are just learning to read and write. Regardless of how much we're coming to rely on computers, printing and handwriting are a necessary skill to have. But typing out assignments has an effect on more than just the ability to print4. It can also negatively impact their spelling and grammar. While most programs now have spell- and grammar-check, they...

...Computers: Grading By JOHN MARKOFF Published: April 4, 2013 Imagine taking a college exam, and, instead of handing in a blue book and getting a grade from a professor a few weeks later, clicking the “send” button when you are done and receiving a grade back instantly, your essay scored by a software program. And then, instead of being done with that exam, imagine that the system would immediately let you rewrite the test to try to improve your grade. EdX, the nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology to offer courses on the Internet, has just introduced such a system and will make its automated software available free on the Web to any institution that wants to use it. The software uses artificial intelligence to grade student essays and short written answers, freeing professors for other tasks. The new service will bring the educational consortium into a growing conflict over the role of automation in education. Although automated grading systems for multiple-choice and true-false tests are now widespread, the use of artificial intelligence technology to grade essay answers has not yet received widespread endorsement by educators and has many critics. Anant Agarwal, an electrical engineer who is president of EdX, predicted that the instant-grading software would be a useful pedagogical tool, enabling students to take tests and write essays over and over and improve the quality of their answers. He said the technology would offer...

...Journal of Information Technology Education Volume 2, 2003 An Overview of Current Research on Automated Essay Grading Salvatore Valenti, Francesca Neri and Alessandro Cucchiarelli DIIGA - Universita’ Politecnica delle Marche, Ancona, Italy valenti@inform.unian.it neri@inform.unian.it alex@inform.unian.it Executive Summary Essays are considered by many researchers as the most useful tool to assess learning outcomes, implying the ability to recall, organize and integrate ideas, the ability to express oneself in writing and the ability to supply merely than identify interpretation and application of data. It is in the measurement of such outcomes, corresponding to the evaluation and synthesis levels of the Bloom’s (1956) taxonomy that the essay questions serve their most useful purpose. One of the difficulties of grading essays is represented by the perceived subjectivity of the grading process. Many researchers claim that the subjective nature of essay assessment leads to variation in grades awarded by different human assessors, which is perceived by students as a great source of unfairness. This issue may be faced through the adoption of automated assessment tools for essays. A system for automated assessment would at least be consistent in the way it scores essays, and enormous cost and time savings could be achieved if the system can be shown to grade essays within the range of those awarded by human assessors. This paper presents an overview of current approaches to...

...Intervention in International Business GOVERNMENT INTERVENTION 1. In a short essay, describe two methods of government intervention. What is the purpose of government intervention in international business? Answer Government intervention is often manifested as protectionism. Protectionism refers to national economic policies designed to restrict free trade and protect domestic industries from foreign competition. Protectionism often leads to two types of intervention: tariffs and nontariff barriers. A tariff is a tax imposed by government on imported products, effectively increasing cost of acquisition for the customer. A nontariff trade barrier, such as a quota, is a government policy, regulation, or procedure that impedes trade through means other than explicit tariffs. Governments intervene in trade and investment to achieve political, social, or economic objectives. Barriers are often applied to benefit specific interest groups, such as domestic firms, industries, and labor unions. A key rationale is to create jobs by protecting industries from foreign competition. Governments may also intervene to support home-grown industries or firms. In various ways, government intervention alters the competitive positions of companies and industries, and the status of citizens. (pp. 195-196; concept; Learning Objective 1; moderate; AACSB: Analytic Skills) RATIONALE FOR GOVERNMENT INTERVENTION 2. In a short essay, explain the four main motives for government intervention in international...

...1080/15305058.2012.690012 Writing Essays on a Laptop or a Desktop Computer: Does It Matter? Guangming Ling and Brent Bridgeman Educational Testing Service To explore the potential effect of computer type on the Test of English as a Foreign Language–Internet-Based Test (TOEFL iBT) Writing Test, a sample of 444 international students was used. The students were randomly assigned to either a laptop or a desktop computer to write two TOEFL iBT practice essays in a simulated testing environment, followed by a survey of computer experience. The survey results suggested that the participants had extensive experience using computers, had more experience with laptops than with desktops, and preferred using the laptop computers to the desktop computers. The computer type (laptop or desktop computer) was found to have a negligible effect on essay performance (essay score, essay length, and writing speed). However, other factors, including gender, regional background, daily experience with laptop or desktop computers, preference for a particular pointing device, and previous TOEFL experience, were found to be significantly related to essay performance but did not interact with computer type. Keywords: computer type effects, desktop, e-rater, essay length, essay score, laptop, writing speed INTRODUCTION When large-scale computer-based testing began in the early 1990s, testing centers were equipped with standard desktop computers. At the time, this was the computer type most familiar to students...

...In Harlan Coben’s essay, “The Undercover Parent,” he makes a case that justifies the use of spyware by parents to monitor their children’s computer usage. His essay is put together well, and he makes his case effectively to the reader. Examples of this can be seen in how he acknowledges the arguments that those against his opinion may make, and he does his best to prove them wrong. His use of organization, seen in how he gets the reader hooked in the first paragraph, goes through his counter arguments in the body, and provides examples throughout that prove to the reader this is an effective method, flow well with one another. By using anecdotes of friends who have used this method, he gives reassurance to the reader that spyware is truly a helpful tool that parents should use, but this method falls a little short. However, as well written as this essay is, many people, myself included, will still find themselves disagreeing with Coben, such as myself. In analyzing his essay, one can see that he makes his case well, through his use of organization, counter arguments, and anecdotes - however this may not be enough to convince the reader...

I will now start with how this program can be useful. This program useful at home or any personal computer. If you are looking for a certain video on YouTube and you finally found it, this program will allow you to take a video of the video. If you are having an issue with your computer and can’t fix it yourself, you can take a screen capture and send it to a friend who knows how to fix computers and can fix your problem. I know taking your computer to a PC repair place can get pretty expensive, with this program you can see if a friend can fix it first. I believe that I would use this program in the future, because I still don’t know too much about computers. Instead of me trying to explain over the phone with my computer friend what the problem I would send him a screen capture instead, this way he could see what I am seeing on my end. In this essay, I explained the program Snagit 13. How this program can be useful at home for a couple of reasons.

...Study 11: Should a Computer Grade Your Essays? The case study discusses the April 2013 launch of Harvard/MIT’s joint venture MOOC (massively open online course) essay scoring program, utilizing AI (artificial intelligence) technology to grade educational essays and short answers, with immediate feedback and ability to revise, resubmit, and improve grades. In 2012, a group of colleagues, Les Perleman, Mark Shermis, and Ben Hamner, introduced over 16,000, K7-12 standardized school tests to the AES (automated essay scoring software) to compare results of hand-scored essays; the results appeared to produce a more accurate grade, however, no official statistical studies were performed to accurately maintain the claim. Essay Raters (e-Rater), developed by the Educational Testing Service (ETS), allowed Perelman to access, and analyze the technology. ETS uses vocabulary and content to score criteria, such as essay length, conjunctive adverb usage, and large word usage, in combination with paper and word length, words per sentence, and word complexity. The downside is the programs’ inability to differentiate factual from nonfactual information, intent, or meaning. Some educators banned to form the group, Professionals Against Machine Scoring of Student Essays in High-Stakes Assessment; they are concerned educators will reduce writing standards to conform to software constraints. Laudon & Laudon further discuss the probability of lost jobs due to computers taking the place of...

...Essay Computers are becoming common in family and hence children have more time using the computers. In other words, it takes children an increasing amount of time on computers. Nevertheless,some studies suggest that children are affected a lot in negative aspect by using computers excessively. The essay will explain the effect of computer use on children, focusing on children’s physical health, psychological health and development. Being exposed to computer for prolonged periods is harmful for children’s physical health. Children’s muscles are likely to be injured since the design of computer use workstation is not suitable for children (Shields&Behrman,2001). In addition, children may be overweight when using computers for extended periods of time and hence the possibility of obesity is increased. As children spend their time playing computer games instead of doing some physical exercises, their body can easily get weaker. More than two hundred people suffer injury from excessive computer use, which is reported by the Occupational Safety and Health Administration (Shields&Behrman,2001). The psychological health is also be negatively affected by excessive computer use. An in-depth analysis about the effects on children suggests that children who are addicted to computers often feel lonely and depressed (Shields& Behrman, 2001), because they have little time communicating with other people. The research on violent computer games suggests that playing such games...
