Computer Science Essay
Computer Science Computer science is one of the fastest growing career fields in modern history. Dating back only a few decades to the late 1950's and early 1960's, it has become on of the leading industries in the world today. Developed through the technological architecture of electrical engineering and the computational language of mathematics, the science of computer technology has provided considerable recognition and financial gain for many of its well deserving pioneers. Originally conceived as an organizational solution to the massive amounts of information kept on nothing more than paper, computers have evolved and advanced to become a common part of modern day life. In the early days of the computer age, the newest and most...show more content...
It is essentially the brain of the computer and though it is the main determining factor in the processing power of the computer as a whole, many other parts of the machine are just as important in overall performance. Many people don't know this and that is how computer corporations have cheated people out of their money for so many years by selling them cheep systems with high megahertz numbers for the processors in them. This is one reason for the success of the computer industry. When people find out that they have been cheated, they will try to learn more about the product and probably end up spending more money next time. Either way the computer companies always win. A career in the field of computer science has been proven to be a worthwhile direction for any young enthusiast and this tren is looking just as bright in the new millenium. Computer science and technology has much to offer in anyone of its many career paths. Whether working with a large multinational corporation or a smaller private company on computer hardware or software in engineering or programming, the possibilities and opportunities are endless and are increasing everyday. One reason the computer industry is so promising is that virtually every industry in the world depends on computers to operate. This creates an increasingly large and permanent demand for computer hardware, software, and the technical knowledge to create and use them. Computer games have

Transfer of Learning
Transfer of learning is the study of the dependency of human conduct, learning, or performance on prior experience. The notion was originally introduced as transfer of practice by Edward Thorndike and Robert S. Woodworth. They explored how individuals would transfer learning in one context to another context that shared similar characteristics – or more formally how "improvement in one mental function" could influence another related one. Their theory implied that transfer of learning depends on the proportion to which the learning task and the transfer task are similar, or where "identical elements are concerned in the influencing and influenced function", now known as identical element theory. Transfer research has since attracted much...show more content...
negative transfer
Starting by looking at the effect side of transfer – in terms of the common performance criteria, speed and accuracy – transfer theories distinguish between two broad classes that underlie all other classifications: negative andpositive transfer. Negative transfer refers to the impairment of current learning and performance due to the application of non–adaptive or inappropriate information or behavior. Therefore, negative transfer is a type of interference effect of prior experience causing a slow–down in learning, completion or solving of a new task when compared to the performance of a hypothetical control group with no respective prior experience. Positive transfer, in contrast, emphasizes the beneficial effects of prior experience on current thinking and action. It is important to understand that the positive and negative effects of transfer are not mutually exclusive, and therefore real–life transfer effects are probably mostly a mixture of both. Positive transfer: transfer of learning or training is said to be positive when the learning or training carried out in one situation proves helpful to learning in another situation. Examples of such transfer are:
