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.

Bureaucratic data bunkers Among the foremost of the data bunkers government bureaucracies. Bureaucracies are the oldest forms of bunkers and are today deeply engrained in modern societies. Bureaucracies have always had the function of collecting and administering the data of subjects. What make this process more problematic in the age of ICT is that a lot more data can be collected, they can be collected in clandestine ways (e.g. in surveillance situations), and the can be combined and merged using advanced data mining technologies. In addition, there is a greater rationale for official data collecting, as a lot more data is required for the functioning of public administration as in previous periods, as societies rush to adopt increasingly complex technologies, above all ICTs. The increasing complexity of modern societies means that an increasing number of bureaucratic decision is taken, all of which require a calculation process. Complexity, viewed through government spectacles, generates insecurity - a great deal of the bureaucratic activity therefore revolves around the topic of security. In spite of the anti-bureaucratic rhetoric of most governments, these factors provides the bureaucracies with an increased hold on society. Foremost bureaucratic data bunkers include the following:
Fiscal agencies Intelligence agencies Social welfare agencies Social insurance institutions Public health agencies Educational institutions These are agencies that enjoy the privileged protection of the state. Those among them that operate in the field of security are further protected against public scrutiny, as they operate in an area to which democratic reason has no access. What makes the data repositories of these institutions different from private data bunkers is their "official", i.e. their politically binding and definitive character. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Censorship of Online Content in China During the Tian-an men massacre reports and photos transmitted by fax machines gave notice of what was happening only with a short delay. The Chinese government has learned his lesson well and "regulated" Internet access from the beginning. All Internet traffic to and out of China passes through a few Users are expected not to "harm" China's national interests and therefore have to apply for permission of Internet access; Web pages have to be approved before being published on the Net. For the development of measures to monitor and control Chinese content providers, China's state police has joined forces with the MIT.
