1800 - 1900 A.D. 1801 Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology to process statistical data collected during the US census in 1890, thus speeding up US census data analysis from eight to three years. Hollerith's application of Jacquard's invention was used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone used them for the preparation, storage, and transmission of data for the first time. Through paper tapes telegraph messages could be stored, prepared off-line and sent ten times quicker (up to 400 words per minute). Later similar paper tapes were used for programming computers. 1809 With Samuel Thomas Soemmering's invention of the electrical telegraph the telegraphic transmission of messages was no longer tied to visibility, as it was the case with smoke and light signals networks. Economical and reliable, the electric telegraph became the state-of-the-art communication system for fast data transmissions, even over long distances. Click 1861 The telephone was not invented by Alexander Graham Bell, as is widely held, but by Philipp Reiss, a German teacher. When he demonstrated his invention to important German professors in 1861, it was not enthusiastically greeted. Because of this dismissal, he was not given any financial support for further development. And here Bell comes in: In 1876 he successfully filed a patent for the telephone. Soon afterwards he established the first telephone company. 1866 First functional underwater telegraph cable is laid across the Atlantic 1895 Invention of the wireless telegraph |

Economic structure; transparent customers Following the dynamics of informatised economies, the consumption habits and lifestyles if customers are of great interest. New technologies make it possible to store and combine collected data of an enormous amount of people. User profiling helps companies understand what potential customers might want. Often enough, such data collecting takes place without the customer's knowledge and amounts to spying. "Much of the information collection that occurs on the Internet is invisible to the consumer, which raises serious questions of fairness and informed consent."

Economic structure; introduction "Globalization is to no small extent based upon the rise of rapid global communication networks. Some even go so far as to argue that "information has replaced manufacturing as the foundation of the economy". Indeed, global media and communication are in some respects the advancing armies of global capitalism." (Robert McChesney, author of "Rich Media, Poor Democracy") "Information flow is your lifeblood." (Bill Gates, founder of Microsoft) The usefulness of information and communication technologies increases with the number of people who use them. The more people form part of communication networks, the greater the amount of information that is produced. Microsoft founder Bill Gates dreams of "friction free capitalism", a new stage of capitalism in which perfect information becomes the basis for the perfection of the markets. But exploitative practices have not disappeared. Instead, they have colonised the digital arena where effective protective regulation is still largely absent.

Proxy Servers A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that security, administrative control, and caching service can be ensured. A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own Source: Whatis.com |
