Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







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 ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

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 Intelsat, Intersputnik and Inmarsat.

Scheduled privatization of intergovernmental satellite consortia:

Intelsat

200 nations under the leadership of the USA

Intersputnik

1971

23 nations under the leadership of Russia

Inmarsat

1979

158 nations (all members of the International Maritime Organization)

privatized since 1999

Eutelsat

1985

Nearly 50 European nations

2001



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:

    Law enforcement agencies

    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. CAE speak of the bureaucracy as a "concrete form of uninterruptible, official and legitimised memory."

Central processing unit

A CPU is the principal part of any digital computer system, generally composed of the main memory, control unit, and arithmetic-logic unit. It constitutes the physical heart of the entire computer system; to it is linked various peripheral equipment, including input/output devices and auxiliary storage units...

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 gateways, a few entry-points, thus making censorship a relatively easy task. Screened out are web sites of organizations and media which express dissident viewpoints: Taiwan's Democratic Progress Party and Independence Party, The New York Times, CNN, and sites dealing with Tibetan independence and human rights issues.

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.

For further information on Internet censorship, see Human Rights Watch, World Report 1999.
