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." (David Sobel, Electronic Privacy Information Center) |

How the Internet works On the Internet, when you want to retrieve a document from another computer, you request a service from this computer. Your computer is the client, the computer on which the information you want to access is stored, is called the A common set of standards allows the exchange of data and commands independent from locations, time, and operating systems through the Internet. These standards are called communication protocols, or the Internet Protocol Suite, and are implemented in Internet software. Sometimes the Internet Protocol Suite is erroneously identified with Any information to be transferred is broken down into pieces, so-called packets, and the Internet Protocol figures out how the data is supposed to get from A to B by passing through routers. Each packet is "pushed" from router to router via The technique of breaking down all messages and requests into packets has the advantage that a large data bundle (e.g. videos) sent by a single user cannot block a whole network, because the One of the Internet's (and of the Matrix's) beginnings was the Routing around depends on the location of the interruption and on the availability of intersecting points between networks. If, for example, an E-mail message is sent from Brussels to Athens and in Germany a channel is down, it will not affect access very much, the message will be routed around this damage, as long as a major Internet exchange is not affected. However, if access depends on a single backbone connection to the Internet and this connection is cut off, there is no way to route around. In most parts of the world the Internet is therefore vulnerable to disruption. "The idea of the Internet as a highly distributed, redundant global communications system is a myth. Virtually all communications between countries take place through a very small number of bottlenecks, and the available bandwidth isn't that great," says Douglas Barnes. These bottlenecks are the network connections to neighboring countries. Many countries rely on a one single connection to the Net, and in some places, such as the Suez Canal, there is a concentration of fiber-optic cables of critical importance. |

Theoedore Roosevelt With the assassination of President McKinley, Theodore Roosevelt (1858-1919), not quite 43, became the youngest President in the Nation's history. Roosevelt's youth differed sharply from that of the log cabin Presidents. He was born in New York City in 1858 into a wealthy family. Roosevelt steered the United States more actively into world politics. He liked to quote a favorite proverb, "Speak softly and carry a big stick. . . . " He won the Nobel Peace Prize for mediating the Russo-Japanese War. for more information see the official website: |
