summary statistic that measures how equitably income is distributed in a population. It is derived from the Lorenz curve which plots the cumulative percentages of the income and the population against which it is distributed. The line at 45 degrees thus represents perfect equality of incomes. The Gini coefficient is the ratio of the area that lies between the line of equality and the Lorenz curve divided by the total area under the line of equality. A Gini coefficient of 0 represents perfect equality

Primarily‚ computers seem to be a helpful and ideal tool for everyday work. Invented in 1936‚ by Konrad Zuse‚ the computer has grown to a popular item used for adults and kids for work‚ school‚ and fun. This technology makes it simpler to communicate between co-workers to get work done more efficiently using email‚ and also has features such as softwares

If the definition is a machine for performing calculations‚ then the abacus would be considered the first computer‚ but if the definition is a machine for performing calculations automatically‚ then the Z1 made by German scientist Konrad Zuse would be considered the first programmable computer. As the computer progressed‚ RAM (rapid access memory) was introduced in MIT’s Whirlwind in 1955. In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800. (Odom)

Computers: One Major Step in Globalization In 1941‚ a German engineer named Konrad Zuse invented the first computer called the Z3 (http://www.computerhistory.org/timeline/?year=1941). It was a functional program- controlled computer. During this time there was a series of events recorded that entailed the beginning stages of computer use. Over time‚ the development became greater‚ one example being that one computer at that time would be the size of a medium sized room‚ whereas now‚ a computer

TYPE OF ECONOMY The German economy is essentially a social market economy or known as “soziale marktwirtschaft” in German. It was originated and implemented by Christian Democrat Ludwig Erhard‚ Minister of Economics under the Chancellorship of Konrad Adenauer in the early 1960’s in former West Germany. Although the state provided subsidies and controls few segments of the economy‚ “free enterprise” and the “rule of the market” was also promoted as a part of governmental policy. Germany has an

HISTORY OF COMPUTER THE PRE-MECHANICAL AGE: 3000 B.C. – 1450 A.D. 1. Writing and Alphabets – Communication First development of signs corresponding to spoken sounds‚ instead of pictures‚ to express words. Around 2000 B.C.‚ Phoenicians created symbols that expressed single syllables and consonants (the first true alphabet) The Greeks later adopted the Phoenician alphabet and added vowels; the Romans gave the letters Latin names to create the alphabet we use today. 2.

The Gini index is a standard economic measure of income inequality‚ based on Lorenz Curve. A society that scores 0.0 on the Gini scale has perfect equality in income distribution. Higher the number over 0 higher the inequality‚ and the score of 100 indicated total inequality where only one person corners all the income (Business

method of measuring. As explained by the World Bank‚ the coefficient varies between 0‚ which reflects complete equality‚ and 1‚ which indicates complete inequality. Graphically‚ the Gini coefficient can be easily represented by the area between the Lorenz curve and the line of equality. Causes for Inequality There are many causes for economic inequality within societies. The factors that affect disparity the most are: market economies‚ and access to education. Market economies became a major cause

Therefore it is used as an indication of income inequality within countries. Practically‚ it measures the area between the Lorenz curve‚ a standard indicator of the distribution of income within a community‚ and a hypothetical line of absolute equality‚ expressed as a percentage of the maximum area under the line. In this index‚ 0 represents perfect equality‚ while 100 perfect
