Evolution of Computers :: essays research papers fc

How m whatsoever inventions in your lifetime can you conjecture of that have changed everything in our society today? Computers have taken over todays society. From everyday tasks to moving satellites in space, PCs have revolutionized near everything in our society. Computers werent always this complicated though, and were around a yen time before anyone even knew what the word computer meant.The Abacus was the first cognise machine developed to help perform numeric equations. From what researchers have notice 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 whatever of todays 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 g enus Musa Abu Djefar. The subject 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 without numbers computers wouldnt exist or have any reason 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 scheming Clock which would perform operations like addition, subtraction, multiplication, and division. In the grade 1801 Jacquard hover devised a punch card system with a power pout and an automatic card reader. Later that century in 1890 Herman Hollerith invented a count calculator that put each persons information on a punch card and sent it through an electrical/ automatonlike tabulating machine. This sped up the process from about 7 long time 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 employ vacuum tubes, an electronic device in which conduction by electrons takes present through a vacuum within a sealed sugarcoat or metal container and which has different 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).
