Personal Computers - Essay Example

Summary
There has been an explosive growth in the demand of personal computers in the last decade. The prices of the first personal computers were very high as compared to the computing power they offered. PCs were found in few businesses and fewer homes. It is hard to believe that just 20 years ago students wrote most of their papers in longhand and did most of their calculations by using a simple calculator…

Download file to see previous pages Worldwide, PC sales totalled about 100 million in 2002 (Samuelson, Nordhaus 2003). In the wake of falling prices, PC industry has experienced a continuous boom. Today, PC has become an indispensable product. This paper will discuss the factors that have had an impact on the price pattern of this indispensable product. To do so, some basic concepts of economics will be introduced.
A market is a mechanism through which buys and sellers interact to determine prices and exchange goods and services. Prices direct the decisions of consumers and producers in the market. Higher prices tend to reduce consumer purchases and encourage production. Contrariwise, lower prices encourage consumption and dampen production. Therefore, prices are the balance wheel of the market mechanism (Samuelson, Nordhaus 2003). The following graph justifies this concept:
It is imperative that an accurate interpretation regarding changes in price and quantity of a particular product is done. This is because the change in quantity as a result of a change in price could be instigated from either the demand side or the supply side (McCain 1981). For example, if fewer airline tickets are sold, it could either mean that the airfares have surged or demand for travel has plummeted. Studying the price behaviour in conjunction with the quantity can sometimes lead to meaningful conclusions. This can be substantiated with a change in the price of bread leading to a change in quantity demanded. Rising price of bread leading to reduced sales suggests a decrease in supply and therefore, a change in the supply curve to the left. On the other hand, rising price of bread leading to a surge in sales indicates that demand has outweighed supply.
In relation to demand and supply, it is important to introduce the concept of elasticity. Elasticity refers to the degree of responsiveness in supply or demand in relation to changes in price (McCain 1981). If demand is elastic, it means a small change in price will cause a significant change in demand. An inelastic demand, on the other hand, does not reveal the same characteristics. Following is a graphical representation of elasticity of demand:
(http://www.sparknotes.com/economics/micro/elasticity/section1.html)
Goods that have ready substitutes tend to have more elastic demand than those without any substitutes. Food, for example, is demand-inelastic as there is no substitute for it. So even if the prices do increase, there will be no effect on the quantity consumed. On the other hand, if price of coffee goes up, consumers have substitutes to choose from, like tea or cola and this may cause a drop in demand.
Economic history indicates that the total output in the United States has increased tenfold over the last century. Much of this increase in output stems from the technological change which has improved productivity. An example of a technological change is when a firm adjusts its production process to reduce waste and increase output. This is termed as process innovation and it differs from product innovation whereby innovative products are introduced in the marketplace (Russell, Wilkinson 1979).

Personal Effectiveness

One of the most difficult prospects is identifying where your strengths lie and in which new role you would be good at. There are hundreds of skills that you developed over time, but it is even more challenging to combine which tasks you are good at and which ones you enjoy the most. The reconciliation of both will determine your strengths. I am trying to identify my weaknesses and strengths all the time in order to make the most of my career opportunities. Besides, I realize that it is easier to focus on and develop your strengths than trying to eliminate weaknesses. Every time I try to engage in a new activity, I am always naturally worried that I won't have the necessary skills for a new activity or responsibility.

Personal Space and Gender

Many factors determine whether people perceive the invasion of their personal space, for example, the person standing next to them (a friend or a stranger) and how close does the stand next to them. Factors like the gender of the person and those of the people around him also have importance.
Generally, as research suggests, most people perceive themselves as "surrounded by a three-foot oblong bubble of personal space" (Arliss, 2000, as cited in Naidoo, 2000). Based up Naidoos (2000) observances and previous research, men demand and claim more personal space than women. This matches what we found in our research.
We also wanted to see how personal space and comfort relate or depend on gender. We, therefore, used two grou...

My Personal Development Planning

It also helps to define the appropriate development to meet those perceived needs. Scheduling and timing are important but cannot be too regimented.” (Personal Development Planning time management).

Time is one of the most essential elements of human life and its proper management is required for the personal development of human beings. Time management has been defined in different ways and a good understanding of the concept may be arrived at from the following definitions. “Time management is a set of principles, practices, skills, tools, and systems that work together to help you get more value out of your time with the aim of improving the quality of your life.” (Definition of Time Management. 200...

Structural-Functional and Symbolic Interactionism Theory as Applied to a Personal Experience

Janina has tried for a US visa a number of times, and every time, she came home disappointed at having been denied. In the structural-functional theory, the US embassy is an institution that functions to screen prospective visitors to their country. Inherent in the structure is inequality in terms of not being able to provide a visa to everyone who applies. Since Janina is one of the unfortunate ones who was never granted a visa in all the times she tried to acquire one, her frustration has created a different meaning for the US embassy. Where before, the US Embassy has symbolized for her a gateway to fulfilling her dreams of visiting the US, her painful denials in being granted a visa has now been instrumental in it being a symbo...

Implications for Personal Investment

The assumption of perfect rationality can be rebutted by the fact that rationality is not the sole driver of human behaviour. On the contrary, our behaviour is contingent upon emotions such as love, fear, pain, and pleasure etc. Human beings only use their intellectual power to achieve or avoid these emotional outcomes (Pompian 2006). Secondly, the assumption of self-interested is also not deemed to be practical because many sociological studies have shown that people are not always self-interested. Had this been the case, then there would not have been a single philanthropist in the world, even people would have avoided negative behaviour such as suicide and alcoholism. The final assumption of perfect information also does not ho...

Reflecting on Personal Life Experiences Utilizing Sociological Perspectives

The experience would touch on my initiation to my very first educational experience and developing my primary group in school.

Secondly, I would reflect on my studies during elementary years in a small exclusive private school in Vietnam. The next phase I consider of great significance in my academic experience is the privilege given me during my 9th grade to 12th-grade studies in a relatively different culture, in Melbourne, Australia.

Finally, a milestone in this journey through life is the recent migration to the United States to complete my higher education with Chemistry as my major in Evergreen Valley College, San Jose, California.

The evolution of sociology could be traced to the development...

Personal Management Framework

The subsequent framework would engender a theoretically determined structure of aims thus bringing up and addressing related issues.

Management functions - planning, leading, organizing and controlling or coordinating – have both a theoretical and conceptual determination and their functional level parameters include such organizational goal-related outcomes (Cleland & Gareis, 2006). For instance, the following process diagram of a personal management framework shows the managerial functions can be more meaningful in an individualized organizational context where the manger’s own capabilities and skills are brought into sharp focus in comparison with the daily and routine functions.

A function...

Using Computers to Teach Mathematics is Better than Traditional Methods

...Using computers to teach Mathematics is better than traditional methods Computer technology has changed the face of education, and is a useful tool in the teaching of other subjects as well with Mathematics being no exception. Various calculating devices have long been used in Mathematics, but the computer offers an even greater potential. Some teachers are reluctant to use computers, for example on the grounds that it is an expensive option and not every child has access to one at home, but its prevalence nowadays means that students should be given the opportunity to use computers in their Mathematics lessons. They have the advantage of being able to make complex calculations much quicker, demonstrate graphical visualisations, instilling...

Uniqueness for Personal Identity

Teleportation is the process of disintegrating the body to make a copy of a person in another place say, for example, Jupiter as a means of travel. In the teleportation experiment, Parfit demonstrated the problem of teleportation when the machine malfunctioned. The machine was not able to destroy the original body and yet a copy was already sent to Mars. So the problem arises of determining who is the real you? This phenomenon of teleportation is bad because it is problematic. It is problematic not only in the sense that the machine malfunctioned that there became two individuals because the original was not destroyed. It is mind-boggling, but we cannot cease to wonder how does the copy thinks? About himself, the universe around h...

Personal Rrofessional Development

Another challenge I faced was time management. I had limited time to study since I worked on a full-time basis. My poor time management skills worsened the matter for me. Indeed, this made me fail in my first presentation and essay despite starting work on it early enough. I had reserved two hours every day for my essay, as opposed to waiting until the last night before the presentation when I would be forced to work on it in a hurry. I also reserved time for my work-related tasks as well as relaxation in order to avoid exhaustion and boredom. However, I still failed. Still, on time management, I found it difficult to balance my time so as to have adequate time for each assignment. This could cause me to take up many tasks at the...
