2000 A.D. 2000 Digital technologies are used to combine previously separated communication and media systems such as telephony, audiovisual technologies and computing to new services and technologies, thus forming extensions of existing communication systems and resulting in fundamentally new communication systems. This is what is meant by today's new buzzwords "multimedia" and "convergence". Classical dichotomies as the one of computing and telephony and traditional categorizations no longer apply, because these new services no longer fit traditional categories. Convergence and Regulatory Institutions Digital technology permits the integration of telecommunications with computing and audiovisual technologies. New services that extend existing communication systems emerge. The convergence of communication and media systems corresponds to a convergence of corporations. Recently, For further information on this issue see Natascha Just and Michael Latzer, The European Policy Response to Convergence with Special Consideration of Competition Policy and Market Power Control, http://www.soe.oeaw.ac.at/workpap.htm or |

1960s - 1970s: Increased Research in Artificial Intelligence (AI) During the cold war the U.S. tried to ensure that it would stay ahead of the Soviet Union in technological advancements. Therefore in 1963 the In the 1960s and 1970s a multitude of AI programs were developed, most notably SHRDLU. Headed by Marvin Minsky the MIT's research team showed, that when confined to a small subject matter, computer programs could solve spatial and logic problems. Other progresses in the field of AI at the time were: the proposal of new theories about |

Late 1960s - Early 1970s: Third Generation Computers One of the most important advances in the development of computer hardware in the late 1960s and early 1970s was the invention of the Another type of computer developed at the time was the minicomputer. It profited from the progresses in microelectronics and was considerably smaller than the standard mainframe, but, for instance, powerful enough to control the instruments of an entire scientific laboratory.

History: "Indigenous Tradition" In preliterate societies the association of rhythmic or repetitively patterned utterances with supernatural knowledge endures well into historic times. Knowledge is passed from one generation to another. Similar as in the Southern tradition |

DES The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys. for more information see: |

Optical communication system by Aeneas Tacitus, 4th century B.C. Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of message transmissions while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by torch signal that the appropriate water level has been reached. It is a disadvantage that the possible messages are restricted to a given code, but as this system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand these messages unless they possessed the codebook. With communication separated from transportation, the distant became near. Tacitus' telegraph system was very fast and not excelled until For further information see Joanne Chang & Anna Soellner, Decoding Device, |

Internet Protocol Number (IP Number) Every computer using IP numbers are divided into three classes. Class A is restricted for big-sized organizations, Class B to medium-sized ones as universities, and Class C is dedicated to small networks. Because of the increasing number of networks worldwide, networks belonging together, as |
