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

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.

Steganography
Applied to electronic files, steganography refers to the process of hiding information in files that can not be easily detected by users. Steganography can be used by intellectual property owners in a variety of ways. One is to insert into the file a "digital watermark" which can be used to prove that an infringing file was the creation of the copyright holder and not the pirate. Other possibilities are to encode a unique serial number into each authorized copy or file, enabling the owner to trace infringing copies to a particular source, or to store
Agents
Agents are programs that can implement specified commands automatically. Copyright owners can use agents to search the public spaces of the Internet to find infringing copies. Although the technology is not yet very well developed full-text search engines allow similar uses.
Copyright Litigation
While not every infringement will be the subject of litigation, the threat of litigation helps keep large pirate operations in check. It helps copyright owners obtain relief for specific acts of infringement and publicly warns others of the dangers of infringement.

Copyright is not only about protecting the rights of creators, but has also become a major branch of industry with significant contributions to the global economy. According to the

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.

Following the dynamics of informatised economies, the consumption habits and lifestyles if customers are of great interest. New technologies make it possible to store and combine collected data of an enormous amount of people.
User profiling helps companies understand what potential customers might want. Often enough, such data collecting takes place without the customer's knowledge and amounts to spying.
"Much of the information collection that occurs on the Internet is invisible to the consumer, which raises serious questions of fairness and informed consent."

An operating system is software that controls the many different operations of a computer and directs and coordinates its processing of programs. It is a remarkably complex set of instructions that schedules the series of jobs (user applications) to be performed by the computer and allocates them to the computer's various hardware systems, such as the

Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets are used for administrative purposes. As an instrument for the administrative bodies of early empires, who began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to a few. Being more or less separated tasks, writing and calculating converge in today's computers.
Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China.
Since the end of June in France anonymous publishing - on the World Wide Web, in newsgroups, mailing lists or chat rooms - is prohibited. The use of pseudonyms, so popular in chat rooms, e.g., is not restricted, but the true identities of those who "publish" on the Net must be known to the users' Internet service and Internet content providers. Additionally, Internet providers are obliged to point out the possibility of blocking access to material to their customers and to offer them appropriate technology for blocking access.
