How the Internet works On the Internet, when you want to retrieve a document from another computer, you request a service from this computer. Your computer is the client, the computer on which the information you want to access is stored, is called the A common set of standards allows the exchange of data and commands independent from locations, time, and operating systems through the Internet. These standards are called communication protocols, or the Internet Protocol Suite, and are implemented in Internet software. Sometimes the Internet Protocol Suite is erroneously identified with Any information to be transferred is broken down into pieces, so-called packets, and the Internet Protocol figures out how the data is supposed to get from A to B by passing through routers. Each packet is "pushed" from router to router via The technique of breaking down all messages and requests into packets has the advantage that a large data bundle (e.g. videos) sent by a single user cannot block a whole network, because the One of the Internet's (and of the Matrix's) beginnings was the Routing around depends on the location of the interruption and on the availability of intersecting points between networks. If, for example, an E-mail message is sent from Brussels to Athens and in Germany a channel is down, it will not affect access very much, the message will be routed around this damage, as long as a major Internet exchange is not affected. However, if access depends on a single backbone connection to the Internet and this connection is cut off, there is no way to route around. In most parts of the world the Internet is therefore vulnerable to disruption. "The idea of the Internet as a highly distributed, redundant global communications system is a myth. Virtually all communications between countries take place through a very small number of bottlenecks, and the available bandwidth isn't that great," says Douglas Barnes. These bottlenecks are the network connections to neighboring countries. Many countries rely on a one single connection to the Net, and in some places, such as the Suez Canal, there is a concentration of fiber-optic cables of critical importance. |

Recent "Digital Copyright" Legislation: European Union Directive on Copyright and Related Rights in the Information Society In November 1996 the European Commission adopted a communication concerning the follow-up to the Green Paper on - the legal protection of computer programs - rental right, lending right and certain rights related to copyright in the field of - copyright and related rights applicable to broadcasting of programs by satellite and cable retransmission - the term of protection of copyright and certain related rights - the legal protection of databases The proposal was first presented by the Commission in January 1998, amended in May 1999 and currently is at second reading before the Parliament. Final adoption of the Directive could take place at the end of 2000 or the beginning of 2001 respectively. A full-text version for download (pdf file) of the amended proposal for a Directive on copyright and related rights in the Information Society is available on the website of the European Commission (DG Internal Market): General critique concerning the proposed EU Directive includes: - Open networks The new law could require (technological) surveillance of communications to ensure enforcement. Also because Service Providers might be legally liable for transmitting unauthorized copies, the might in turn have to deny access to anybody who could not provide them with financial guaranties or insurance. - Interoperable systems The draft could negate the already established right in EU law for software firms to make their systems interoperable with the dominant copyright protected systems. This would be a threat to the democratic and economic rights of users. - Publicly available information It is yet unclear whether new legal protections against the bypassing of Comments from the library, archives and documentation community on the amended Directive embrace: The Library Association EBLIDA (European Bureau of Library, Information and Documentation Associations) Society of Archivists (U.K.) and Public Record Office (U.K.) EFPICC (European Fair Practices In Copyright Campaign) |
