Evolution of Computers :: essays research papers fc

How many inventions in your lifetime can you think of that have changed everything in our society today? Computers have taken over today’s society. From everyday tasks to moving satellites in space, PCs have revolutionized almost everything in our society. Computers weren’t always this complicated though, and were around a long time before anyone even knew what the word â€Å"computer† meant. The Abacus was the first known machine developed to help perform mathematical equations. From what researchers have discovered it was invented around 500 to 600 BC in an area around China or Egypt. This early tool was used to perform addition and subtraction and can still be found used in some of today’s Middle Eastern cultures. In 650 AD the Hindus invented a written symbol for zero. Before this no true written calculations could be made, making this one of the most essential inventions to help computers. In 830 AD the first mathematics textbook was invented by a man named Mohammed Ibn Musa Abu Djefar. The subject of this textbook he wrote was â€Å"Al Gebr We'l Mukabala† which in today’s society is known as â€Å"Algebra† (History of Computers). So what does all of this have to do with computers? Well without numbers computers wouldn’t exist or have any reason to exist. The whole point of a computer is to perform mathematical computations. Computers weren’t the first to do these mathematical calculations though. In 1623 AD Wilhelm Schickard invented â€Å"The Calculating Clock† which would perform operations like addition, subtraction, multiplication, and division. In the year 1801 Jacquard Loom devised a punch card system with a power loom and an automatic card reader. Later that century in 1890 Herman Hollerith invented a census calculator that put each person’s information on a punch card and sent it through an electrical/mechanical tabulating machine. This sped up the process from about 7 years to 2 years making this a very efficient method of performing a census, which in turn helped spread it around the world (History of Computers). Jump to the year 1937 when John V. Atanasoff invented the first electronic computer. This computer and others below, unless otherwise stated, were made using vacuum tubes, â€Å"an electronic device in which conduction by electrons takes place through a vacuum within a sealed glass or metal container and which has various uses based on the controlled flow of electrons† (Dictionary.com). From 1941 to 1954 the governments of various countries started developing different computers for different purposes (Sandiego 1).

Knights Tale Compare And Contrast Movie And Book Essay

The book and the movie have some similarities, where they use swords to fight, but the movie used more lances for jousting. Comparing both the book and the movie to our real lives, our lives don ¡Ã‚ ¦t have too much in common. In our lives we don ¡Ã‚ ¦t carry around swords, and wear armor, or compete in games with lances. Our competitions usually consist of our bare hands and feet, to fight. In a way we do have a type of sport that is almost similar to sword fighting, which is called  ¡Ã‚ §Fencing. ¡Ã‚ ¨ This is where the rules are almost similar but you fight in different motions. We also have games that use guns also, but they also hurt a lot, this game is called  ¡Ã‚ §paint ball. ¡Ã‚ ¨ Where you try to hunt down your opponent and shoot him before he shoots you with his paint balls. The time periods are different, since the book and the movie are told in the medieval times. While ours is present twentieth century time. We drive cars, ride bikes, or some even ride the buses. In the movie and the book they had mostly rode horses, or walked. In which some cases some people still do walk now to get to certain places. The old ways are also the new ways in religion. Since we still believe in the Christian ways, like they did back in the medieval times, but mainly the English people believe in this. They way they had lived in the medieval times, was that they lived mostly in hard concrete houses, or brick houses. They would use lanterns for their lights, or torches, sometimes even to stay warm they would build a small fire. Now we just build our houses out of wood, but there are still some that are made out of concrete and bricks. The majority of houses are built out of wood, and run on electricity, to heat the house, or to cool it down with the air conditioning. The only time that we light lanterns or fires are when we go out camping, so we bring fire wood, and other equipment ¡Ã‚ ¦s to cook with, such as a small gas stove.
