The best legend story in english investor Charles Babbage worked out the principles behind the general purpose digital computer a full century before the legend story in english development of the large modern electronic calculating machines.A machine he designed,legend story in english which he called the “analytical engine,apable in principal of doing everything that modern calculators can do (though not nearly as quickly,since the analytical engineer was not todesigne opacreat electrically). Unfortunately,legend story in english,
because nineteenth century technology was not sufficiently advanced, Babbage was not able to complete the construction of the analytical engine ,despite the expenditure of a large amount of time and money.After his death ,his legend story in english extremely ingenious ideas were nearly forgotten.In 1937, however, Babbage’s written came to the attention of Howard H .
Aiken ,a graduate student at design a computing machine,was greatly stimulated by Babbage’s ideas with the collaboration of IBM .Aiken was able to construct the mark I, the first large general purpose computer.In 1946,two years after the mark I went into operation, another group of engineers and inventors complete the ENIAC, the first electronic calculating ,the first electronic calculating machine .Since then, advance in computer technology have been extremely rapid since calculating machines have had such a great impact on the word already ,and are likely to prove aver more important in the future .
I was tempted to include Charles Babbage in the main section of this book .After careful consideration however,I conclude that Babbage contribution to the development of conpudge was not significantly greater than that of Aiken,or than that of John muchly and J.P.Eckert (who were the leading figures in the design of the ENIAC).For that matter ,at least three of Babbage’s prefer ccssor Blaise Pascal,a French.Sclentist ,mathematician and philosopher,
invented a mechanical adding machine back in 1642,In 1671, Gottfried wihelim von Leibniz, philosopher and mathematician,devised a machine that could add, subtract, multiply,and divine .Leibniz was also the first to the point out important of the binary system ,a system of notation that is extensively employed in modern computing machines.Jacquard was a Frenchman who ,in the early nineteenth century ,invented a device that employed punched cards to control the operation of a loom.The jacquary loom, which was very successful commercially ,had a significant influence on Babbage’s thinking.
it may also have influenced century,adapted punched cards for use in census Bureau tabulations.The principle credit for the developer of the modern computer must , therefore be divided among several men though each of the men mentioned here made a significant contribution, no one of them stands out clearly above the others.Neither Babbage’s there not any of the others seems quite worthy of inclusion in the main section of this book.
