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.

Biometrics applications: privacy issues All biometric technologies capture biometric data from individuals. Once these date have been captured by a system, they can, in principle, be forwarded to other locations and put to many different uses which are capable of compromising on an individuals privacy. Technically it is easy to match biometric data with other personal data stored in government or corporate files, and to come a step closer to the counter-utopia of the transparent citizen and customer whose data body is under outside control. While biometric technologies are often portrayed as protectors of personal data and safeguards against identity theft, they can thus contribute to an advance in "Big Brother" technology. The combination of personalised data files with biometric data would amount to an enormous control potential. While nobody in government and industry would admit to such intentions, leading data systems companies such as EDS (Electronic Data Systems; Biometric technologies have the function of identification. Historically, identification has been a prerequisite for the exercise of power and serves as a protection only to those who are in no conflict with this power. If the digitalisation of the body by biometric technologies becomes as widespread as its proponents hope, a new electronic feudal system could be emerging, in which people are reduced to subjects dispossessed of their to their bodies, even if these, unlike in the previous one, are data bodies. Unlike the gatekeepers of medieval towns, wear no uniforms by they might be identified; biometric technologies are pure masks. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

General Schwarzkopf General H. Norman Schwarzkopf (* 1934) followed in his father's footsteps at the United States Military Academy at West Point. In 1965 he applied to join the troops in Vietnam. For the next 20 years Schwarzkopf worked on his career. As Commander in Chief of the U.S. Central Command, he led U.S. and allied forces in the Gulf War (Operations Desert Shield and Desert Storm). He retired from the Army in 1992 and wrote his autobiography. For a picture see: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Joseph Stalin Joseph Stalin (1879-1953): After Lenin's death he took over and became a dictator without any limits of power. Everyone who dared to talk or act against him or was in suspicion of doing so, got killed. Millions were murdered. His empire was one made out of propaganda and fear. As long as he was in power his picture had to be in every flat and bureau. Soon after his death the cult was stopped and in 1956 the De-Stalination was started, though he was partly rehabilitated in 1970. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
