Timeline of Communication Systems: Introduction The timeline of communication systems presents a chronological overview of the most important events in the history of communication systems from the 4th millennium B.C. to the present. It shows that from the very beginning - the first Sumerian pictographs on clay tablets to today's state-of-the-art technologies - broadband communication via |

Censored links: Linking as a crime The World Wide Web is constituted by documents linked with other documents, thus allowing access to referred documents. Censorship affects hyperlinks as well. Say, you publish an essay on racist propaganda on the Net and make link references to neo-nazi web sites. It goes without saying that you do not endorse neo-nazi pamphlets. By linking to these web sites you want your readers to get an idea of what you are writing about. Linking does not necessarily mean approving. Is this not evident? According to Swiss and German prosecuting attorneys you may have committed a crime without having illegal intentions. From his web site Thomas Stricker, director of the Institute of Computer Systems at the ETH Zurich, has linked to an anti-racist web site with links to racist content in order to draw the attention to the difficulties legal regulation of the Net has to face. Neglecting his intentions, Swiss authorities instituted a criminal action against Stricker. Another case, reported by the Global Internet Liberty Campaign, proves that not just links to racist resources or to resources with links to such resources are under prosecution. The Motion Picture Association of America sued to prevent Internet users from linking to websites that have DeCSS, a program helping Linux users play DVDs on their computers. The trial is scheduled for December.

Pressures and Attacks against Independent Content Providers: Pakistan The Pakistan Telecommunication Authority (PTA), the licensing authority for electronic services, has imposed a number of restrictions of the use of the Internet. Licenses to ISPs (Internet Service Provider) will be issued under the terms of the highly restrictive Telephone and Telegraph Act of 1885. Under the terms of the agreement, users are prohibited from using any sort of data encryption and have to agree that their electronic communications may be monitored by government agencies. Transmission or reception of obscene or objectionable material is also prohibited and may lead not only to immediate disconnection of service but also to prosecution by authorities. Users of electronic services will also have to submit to service provider's copies of the National Identity Card. According to the terms of issuance of licenses, service providers will also be responsible for ensuring that the programs and information provided through electronic services do not "come into direct clash with accepted standards of morality and social values in Pakistan." |

Commercial vs. Independent Content: Power and Scope Regarding the dimension of their financial and human resources commercial media companies are at any rate much more powerful players than their independent counterparts. Still those reply with an extreme multiplicity and diversity. Today thousands of newsgroups, mailing-list and e-zines covering a wide range of issues from the environment to politics, social and human rights, culture, art and democracy are run by alternative groups. Moreover independent content provider have started to use digital media for communication, information and co-ordination long before they were discovered by corporate interest. They regularly use the Internet and other networks to further public discourse and put up civic resistance. And in many cases are very successful with their work, as initiatives like widerst@ndMUND's (AT) co-ordination of the critics of the participation of the Freedom Party in the Austrian government via mailing-lists, an online-magazine and discussion forums, show. |

French laws against anonymity on the Net 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.

Donna Haraway Ever since the publication of her Cyborg Manifesto Donna Haraway has been providing widely received theoretical contributions to the debate around artificial life. In the "Manifesto" she considers the political and social implications of the advent of artificial beings. A radical feminist, Haraway combines in her theoretical approach philosophy, cultural studies and gender studies. Hyperlink to Donna Haraway: |

Bandwidth 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).
