史前人没有电脑和互联网,电脑的出现是由于他们需要一种方法来计算。显然，人体十个手指和十个脚趾的局限性促使了早期人们构建一个工具来帮助计算。让我们暂停一会儿,仔细想想一下你的生命中典型的一天。早餐你可能坐在一把由一棵生长在瑞典的树做成的椅子上,在当地的面包店吃面包：这个面包的小麦生长于美国，牛肉来自于在爱尔兰长大的牛，而塑料袋是在英国包装的。我们使用的电脑,在中国组装和包装,但电子芯片在美国设计,所以使用了自然或几代人所提供的稀缺资源，人们的需求和选择创建了这样一种行为或社会科学。

在经济学中,市场潜在的卖家和买家之间的关系被称为需求和供应。

Factors That Determine Computer Price In Free Market

In recent years, the price of personal computers has continued to fall even in the face of increasing demand. Analyse with the aid of a diagram how this has occurred.

Introduction:

Prehistoric men did not have the computers and internet but its appears that they needed a way to count and make calculations. The limitations of the human body's ten fingers and ten toes apparently caused early people to construct a tool to help with those calculations. Pause for a moment and consider a typical day in your life. For breakfast you might have sat on a chair from a tree grown in sweden, eaten bread made in a local bakery from wheat grown in the USA and beaf from cows raised in Ireland packaged in plastic bags made in the UK. We use a computer, assembled and packaged in China but electronic chips designed in USA, so people’s needs and choices created such a behavioural or social science where they use scarce resources that nature and previous generations have provided.

In Economics, the market relations between prospective sellers and buyers of a good are known as Demand and Supply. The Price and quantity sold in a market is determined by the Demand and Supply model. The phrase “supply and demand” was first used by James Denham-Steuart in his book named Inquiry in to the Political Economy which was published in 1767. Since the 19th the theory has been unchanged. There is always a change in Demand and Supply of a particular product in a market due to various reasons. There are few products whose demand or supply doesnt change with respect to price. These are known as inelastic products. A very good example of perfectly inelastic product is Pencillinn. There are elastic products too which demand changes with respect to price and people dont hesitate to opt for a cheaper alternative. Tea and coffee are the best example of an elastic product.

This theory focuses on the factors that determine the Demand and Supply of Personal Computers in a free market. The report has been prepared through in-depth analysis of the market. The yearly price and sales of PC’s and through various suppliers are examined and collected obtain this report. After description of the factors affecting Demand and Supply of PC’s graphs are provided to understand the future market as well. Different websites and articles were of great help which were acquired from our college library.

Market Structure :

In 2001, 125 million personal computers were shipped comparison to 48 thousand in 1977. More than 500 million personal computers were in use in 2002 and one billion personal computers had been sold worldwide since mid 1970's until this time. Of the later figure, 75 percent were professional or work related, while the rest sold for personal or home use. About 81.5 percent of personal computers had been shipped desktop computers
