Acessing the Internet The Net connections can be based on wire-line and wireless access technolgies.
Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables Satellite communication Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks. Privatization of satellite communication Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Scheduled privatization of intergovernmental satellite consortia:
When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers. As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost. Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Timeline 1600 - 1900 AD 17th century Cardinal Richelieu invents an encryption-tool called grille, a card with holes for writing messages on paper into the holes of those cards. Afterwards he removes the cards and fills in the blanks, so the message looks like an ordinary letter. The recipient needs to own the same card - Bishop John Wilkins invents a cryptologic system looking like music notes. In a book he describes several forms of steganographic systems like secrets inks, but also the string cipher. He mentions the so-called Pig Latin, a spoken way of encryption that was already used by the ancient Indians - the English scientist, magician and astrologer 1605/1623 Sir Francis Bacon (= Francis Tudor = William Shakespeare?) writes several works containing ideas about cryptography. One of his most important advises is to use ciphers in such a way that no-one gets suspicious that the text could be enciphered. For this the steganogram was the best method, very often used in poems. The attempt to decipher Shakespeare's sonnets (in the 20th century) lead to the idea that his works had been written by Francis Bacon originally. 1671 Leibniz invents a calculating machine that uses the binary scale which we still use today, more advanced of course, called the ASCII code 18th century this is the time of the Black Chambers of espionage in Europe, Vienna having one of the most effective ones, called the "Geheime Kabinettskanzlei", headed by Baron Ignaz von Koch. Its task is to read through international diplomatic mail, copy letters and return them to the post-office the same morning. Supposedly about 100 letters are dealt with each day. 1790's Thomas Jefferson and Robert Patterson invent a wheel cipher 1799 the Rosetta Stone is found and makes it possible to decipher the Egyptian Hieroglyphs 1832 or 1838 Sam Morse develops the Morse Code, which actually is no code but an enciphered alphabet of short and long sounds. The first Morse code-message is sent by telegraph in 1844. 1834 the 1844 the invention of the telegraph changes cryptography very much, as codes are absolutely necessary by then 1854 the Playfair cipher is invented by Sir Charles Wheatstone 1859 for the first time a tomographic cipher gets described 1861 Friedrich W. Kasiski does a cryptoanalysis of the Vigenère ciphers, which had been supposed to be uncrackable for ages 1891 Major Etienne Bazeries creates a new version of the wheel cipher, which is rejected by the French Army 1895 the invention of the radio changes cryptography-tasks again and makes them even more important | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The third industiral revolution. Life as a product. Many years ago, the German philosopher The "third industrial revolution" is characterized by men becoming the "raw material" of their own industries. Product and producer, production and consumption, technology and nature are no longer meaningful pairs of opposites. The third is also the last revolution, as it is difficult to think of further revolutions when the distinction between subject and object becomes blurred. The world is becoming a Bestand and the human body and mind are no protected zones. They are something like the last safety zone of human being which is now itself becoming a basis for technological innovation. When the subject is weakened by its technical environment, the use of technical crooks for body and mind becomes an obvious "solution", even if the technically strengthened subject is strengthened at the cost of no longer being a "subject" in the traditional, metaphysical sense. Biological processes are dissected and subjected to technical control. This technical control is technical in two senses: it is not only control through technology but by ttechnology itsself, since it is not carried out by unaided human minds, but increasingly by intelligent machines. The point where this Andersian third industrial revolution reaches an unprecedented logic seems to lie within the realm of genetic engeneering. This example shows that the dissection of humanness - the decoding of genetic information - is tantamount to commodification. The purpose of the commercial genetic research projects is the use of genetic information as a resource for the development of new products, e.g. in pharmaceutics. Genetic products carry the promise of offering a solution to so-far uncurable diseases such as cancer, Alzeheimer, heart disorders, schizophrenia, and others, but they also open up the possibility of "breaking the chains of evolution", of actively manipulating the genetic structure of human beings and of "designing" healthy, long-living, beautiful, hard-working etc. beings. Here, the homo creator and the homo materia finally become indistinguishable and we are being to merge with our products in such a way that it "we" loses the remains of its meaning. Since 1990 research on human genetics is organised in the But exactly this patentising is of paramount importance in the emerging "post-industrial" society where knowledge becomes the most important resource. A patent is nothing else than a property title to a piece of "know-how", and an necessary consequence commodification. When life no longer simply a natural creation but a product, it, too, will be patented and becomes a commodity. Against the idea of the human genome as a public good, or an "open source", there is a growing competion on the part of private industry. Companies such as But the commodification of life is not limited ot the human species. Genetically altered animals and plants are also suffering the same fate, and in most industrialised nations it is now possible to patent genetically engeneered species and crops. The promises of the "Green Revolution" of the 1960s are now repeated in the genetic revolution. Genetic engeneering, so it is argued, will be able to breed animals and plants which resist disease and yield more "food" and will therfore help to tackle problems of undernutrition and starvation.

United Brands Company American corporation formed in 1970 in the merger of United Fruit Company and AMK Corporation. United Fruit Company, the main company, was founded in 1899 producing and marketing bananas grown in the Caribbean islands, Central America, and Colombia. The principal founder was Minor C. Keith, who had begun to acquire banana plantations and to build a railroad in Costa Rica as early as 1872. In 1884 he contracted with the Costa Rican government to fund the national debt and to lay about 50 more miles of track. In return he received, for 99 years, full rights to these rail lines and 800,000 acres of virgin land, tax exempt for 20 years. By 1930 it had absorbed 20 rival firms and became the largest employer in Central America. As a foreign corporation of conspicuous size, United Fruit sometimes became the target of popular attacks. The Latin-American press often referred to it as el pulpo ("the octopus"), accusing it of exploiting labourers, bribing officials, and influencing governments during the period of Yankee "dollar diplomacy" in the first decades of the 20th century. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Edward L. Bernays Born 1891 in Vienna, Bernays was one of the founders of modern public relations. An enigmatic character, he was a master of mise en scène with far-reaching contacts in the world of business and politics. The nephew of Sigmund Freund and related with Heinrich Heine, he was also among the first to pursue PR for governments and to produce pseudo-events. Bernays considered the manipulation of public opinion as an important element of mass democracies and was of the opinion that only through PR a society's order can be kept. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
