Evolution of Computers :: essays research papers fc

How many inventions in your life term trick you think of that have a bun in the oven changed everything in our golf club nowadays? Computers have taken over straight offs society. From everyday tasks to moving satellites in space, PCs have revolutionized almost everything in our society. Computers werent always this complicated though, and were approximately a long time before anyone even knew what the word computer meant.The Abacus was the starting time known mechanism 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 todays Middle Eastern cultures. In 650 AD the Hindus invented a indite symbol for zero. Before this no true written calculations could be made, devising this one of the most essential inventions to help computers. In 830 AD the first mathematics textboo k was invented by a man named Mohammed Ibn Musa Abu Djefar. The type of this textbook he wrote was Al Gebr Wel Mukabala which in todays society is known as Algebra (History of Computers).So what does all of this have to do with computers? well up without numbers computers wouldnt exist or have any rationalness to exist. The whole point of a computer is to perform mathematical computations. Computers werent the first to do these mathematical calculations though. In 1623 AD Wilhelm Schickard invented The Calculating measure 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 self-acting card reader. Later that century in 1890 Herman Hollerith invented a census computing machine that put each persons 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 qualification 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 tail V. Atanasoff invented the first electronic computer. This computer and others below, unless otherwise stated, were made using void tubes, 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 growth different computers for different purposes (Sandiego 1).
