Human Computer Interaction - Essay Example The other assumption is that the virus might have been obtained from other computers through transfer of files using a flash disk. Some of the factors that contributed to this problem include ignorance, whereby my antivirus program was out-to-date and I had not taken any measures to update it or else purchase a newer version. On the other hand, before the presentation, I had been transferring files from computers belonging to all group members. In case, I gathered all their work and transferred it my computer using a flash disk. One of the factors that can be minimized include ignorance, whereby I can ensure that my computer is set to update the antivirus program automatically. On the other hand, I should avoid sharing files using flash disks from different computers since they are likely to have malicious viruses. Nonetheless, one of the possible sources of progress is the lesion that I learnt, whereby I discovered that I could have avoided this incidence by asking the group members to send their work to my email address, and later I would have downloaded it without viruses. Human being are known to distort information and as such, second hand information is mostly wrong and could lead to wrong diagnosis; firsthand information is usually valuable in learning and undertaking investigations. For example, at the earlier experience with the use of computers, there were so many theories that were presented in respect to issues such as computer virus attack. While under the attack, the computer graphical user interface would be affected alongside various programs running on the computer. After undertaking research and training on computers, I understood how the virus were transferred and how they affect different functionalities of the computer. This has been useful in avoiding vague information, which might do more harm than good in the diagnosis of computer problems. In the recent past, the use of technology has been integrated in all aspects of our interaction, r anging from work to entertainment. For example, in education sector, technology is used to enhance the learning process; children search for solution to various assignments they are assigned online, as the internet provides a platform through which a variety of materials can be availed. In the engineering sector, complex machines with diverse capabilities have been manufactured to assist making in undertaking various chores. As a result, man have become too dependent on the technology to an extent in which its failure could cause mayhem in the execution of various duties; for example, many institution s across the globe are dependent on computer in running their assignments. As such, in case of a total computer failure, the works would not be executed, which would have adverse negative effect on the institution at large. Cyborg came into existence after the technological development of the human computer interaction. Through technology, the developed creatures are observed to perfor m activities, which are similar to those executed by human beings. In many instances, the term is used to refer to living organisms although other structures are used though at a less frequency. A term such as ‘supercyborg’ would be good enough to describe humans’ interaction with computers; this is because the term

Parity Theories - Essay Example This simply indicates uniformity in the prices of fixed number of goods and services and exchange rate of two countries. The roots of this theory lie in the law of one price, which says that homogenous goods should have identical prices universally not including any carrying or shipping costs under the prevalence of perfect competition if the pertinent national prices are stated in a common currency. The law of one price has certain conditions, which must exist in order for this law to be applicable. Firstly, it is the presence of competitive market for goods and services in two countries (EconomyWatch, 2010). Secondly, presence of goods and services that two countries can trade between themselves and lastly, checking of transportation and other operational expenses, which are obstructions in trade. Taking example of McDonald’s Big Mac hamburger prices around the world, one can understand this concept. For this the one should take the prices of all the countries in common curr ency, therefore dollar would be the appropriate one as every currency’s appreciation or depreciation is measured in terms of dollar (Taylor and Taylor, 2004, pp.135-158). In January 2004, the price of hamburger in United States was $2.80 where as in China it was $1.23, least expensive of all countries, this shows that China’s currency was underrated by 56%. ... Moreover, wage rate of the person serving foods at restaurant, rent of place of restaurant, and many other factors in case of businesses other that restaurants, have different costs and values in different countries therefore final prices become very different due to these inputs. In response of question that why countries should adopt Purchasing Power Parity Theory when there are so many discrepancies, one can say that in long-term PPP theory has good effects on the economy of a country. A big retailer may use this theory to find that in what countries products possess lesser prices than the domestic country so that the retailer can approach them. This would increase the demand of that product in the country in which it is of low price leading to increase in price (Murray and Papell, 2005, pp. 410-415). Simultaneously, the countries that were selling the product at a higher price would somehow manage to lower the prices so that demand increases and people purchases from them. Ultima tely, both countries would start offering same prices in spite of differences in the currencies. There are two types of purchasing power parity theories; these are Absolute purchasing power parity and relative purchasing power parity. Absolute purchasing power parity theory suggests that if the prices of goods convert into same currency then a basket of goods would have same cost in the native country as well as abroad. In simple words, absolute purchasing power parity theory assumes that the purchasing power of money should be identical between countries. On the other hand, relative purchasing power parity theory focuses on changes in
