The 19th Century: First Programmable Computing Devices Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early Therefore After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer. The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed. Of extraordinary importance for the evolution of digital computers and |

An Economic and therefore Governmental Issue While the digital divide might bring up the idea that enterprises will be able to sell more and more computers during the next years another truth looks as if there was no hope for a certain percentage of the population to get out of their marginalization, their position of being "have nots". Studies show that the issue of different colors of skin play a role in this, but more than "racial" issues it is income, age and education that decides about the have and have nots. There exist ~ 103 million households in the USA. ~6 million do not even have telephone access. Why should they care about computers? The digital divide cuts the world into centers and peripheries, not into nations, as it runs through the boarder between the North and the South as well as through nations. The most different institutions with various interests in their background work in that field; not rarely paid by governments, which are interested in inhabitants, connected to the net and economy. see also: Searching information about the digital divide one will find informations saying that it is growing all the time whereas other studies suggest the contrary, like this one |

CIA CIA's mission is to support the President, the National Security Council, and all officials who make and execute U.S. national security policy by: Providing accurate, comprehensive, and timely foreign intelligence on national security topics; Conducting counterintelligence activities, special activities, and other functions related to foreign intelligence and national security, as directed by the President. To accomplish its mission, the CIA engages in research, development, and deployment of high-leverage technology for intelligence purposes. As a separate agency, CIA serves as an independent source of analysis on topics of concern and works closely with the other organizations in the Intelligence Community to ensure that the intelligence consumer--whether Washington policymaker or battlefield commander--receives the adaequate intelligence information. http://www.cia.gov |
