- the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes (usually certain types of educational copying are allowed)
- the nature of the copyrighted work (mostly originals made for commercial reasons are less protected than their purely artistic counterparts)
- the amount and substantiality of the portion used in relation to the copyrighted work as a whole
- the effect of the use upon the potential market for or value of the copyrighted work (as a general rule copying may be permitted if it is unlikely to cause economic harm to the original author)
Examples of activities that may be excused as fair use include: providing a quotation in a book review; distributing copies of a section of an article in class for educational purposes; and imitating a work for the purpose of parody or social commentary.

Reproduction and Distribution
Unlike copies of works made using analog copiers (photocopy machines, video recorders etc.) digital information can be reproduced extremely fast, at low cost and without any loss in quality. Since each copy is a perfect copy, no quality-related limits inhibit pirates from making as many copies as they please, and recipients of these copies have no incentive to return to authorized sources to get another qualitatively equal product. Additionally the costs of making one extra copy of intellectual property online are insignificant, as are the distribution costs if the copy is moved to the end user over the Internet.
Control and Manipulation
In cross-border, global data networks it is almost impossible to control the exploitation of protected works. Particularly the use of anonymous remailers and other existing technologies complicates the persecution of pirates. Also digital files are especially vulnerable to manipulation, of the work itself, and of the (in some cases) therein-embedded

It furthermore played a central role in the Gulf War. On behalf of the Kuwaiti government it presented a 15-year-old girl to testify before Congress about human rights violations in a Kuwaiti hospital. The girl, later found out to be the daughter of Kuwait's ambassador to the U.S., and its testimony then became the centerpiece of a finely tuned PR campaign orchestrated by Hill & Knowlton and co-ordinated with the White House on behalf of the government of Kuwait an the Citizens for a Free Kuwait group. Inflaming public opinion against Iraq and bringing the U.S. Congress in favor of war in the Gulf, this probably was one of the largest and most effective public relations campaigns in history.

On the other hand are the data bunkers of the private sector, whose position is different. Although these are fast-growing engines of data collection with a much greater degree of dynamism, they may not have the same privileged position - although one has to differentiate among the general historical and social conditions into which a data bunker is embedded. For example, it can safely be assumed that the databases of a large credit card company or bank are more protected than the bureaucracies of small developing countries.

Until recent years, the problem of piracy (the unauthorized reproduction or distribution of copyrighted works (for commercial purposes)) was largely confined to the copying and physical distribution of tapes, disks and CDs. Yet the emergence and increased use of global data networks and the WWW has added a new dimension to the piracy of
This new development, often referred to as Internet piracy, broadly relates to the use of global data networks to 1) transmit and download digitized copies of pirated works, 2) advertise and market pirated intellectual property that is delivered on physical media through the mails or other traditional means, and 3) offer and transmit codes or other technologies which can be used to circumvent

The result of this informatisation is the creation of a virtual body which is the exterior of a man or woman's social existence. It plays the same role that the physical body, except located in virtual space (it has no real location). The virtual body holds a certain emancipatory potential. It allows us to go to places and to do things which in the physical world would be impossible. It does not have the weight of the physical body, and is less conditioned by physical laws. It therefore allows one to create an identity of one's own, with much less restrictions than would apply in the physical world.
But this new freedom has a price. In the shadow of virtualisation, the data body has emerged. The data body is a virtual body which is composed of the files connected to an individual. As the
The virtual character of the data body means that social regulation that applies to the real body is absent. While there are limits to the manipulation and exploitation of the real body (even if these limits are not respected everywhere), there is little regulation concerning the manipulation and exploitation of the data body, although the manipulation of the data body is much easier to perform than that of the real body. The seizure of the data body from outside the concerned individual is often undetected as it has become part of the basic structure of an informatised society. But data bodies serve as raw material for the "New Economy". Both business and governments claim access to data bodies. Power can be exercised, and democratic decision-taking procedures bypassed by seizing data bodies. This totalitarian potential of the data body makes the data body a deeply problematic phenomenon that calls for an understanding of data as social construction rather than as something representative of an objective reality. How data bodies are generated, what happens to them and who has control over them is therefore a highly relevant political question.

In November 1997, after the assassination of (above all Swiss) tourists in Egypt, the Swiss newspaper Blick showed a picture of the place where the attack had happened, with a tremendous pool of blood, to emphasize the cruelty of the Muslim terrorists. In other newspapers the same picture could be seen - with a pool of water, like in the original. Of course the manipulated coloured version of the Blick fit better into the mind of the shocked Swiss population. The question about death penalty arose quickly ....

Educator who developed a system of printing and writing that is extensively used by the blind and that was named for him. Himself blind Braille became interested in a system of writing, exhibited at the school by Charles Barbier, in which a message coded in dots was embossed on cardboard. When he was 15, he worked out an adaptation, written with a simple instrument, that met the needs of the sightless. He later took this system, which consists of a six-dot code in various combinations, and adapted it to musical notation. He published treatises on his type system in 1829 and 1837.

The Clipper Chip is a cryptographic device proposed by the U.S. government that purportedly intended to protect private communications while at the same time permitting government agents to obtain the "keys" upon presentation of what has been vaguely characterized as "legal authorization." The "keys" are held by two government "escrow agents" and would enable the government to access the encrypted private communication. While Clipper would be used to encrypt voice transmissions, a similar chip known as Capstone
would be used to encrypt data. The underlying cryptographic algorithm, known as Skipjack, was developed by the National Security Agency (NSA).
The telephone was not invented by Alexander Graham Bell, as is widely held to be true, but by Philipp Reiss, a German teacher. When he demonstrated his invention to important German professors in 1861, it was not enthusiastically greeted. Because of this dismissal, no financial support for further development was provided to him.
And here Bell comes in: In 1876 he successfully filed a patent for the telephone. Soon afterwards he established the first telephone company.
The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems.
Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all.
In digital systems, bandwidth is data speed in bits per second (bps).
