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 server. Therefore the Internet's architecture is called client-server architecture.

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 TCP/IP (Transmission Control Protocol / Internet Protocol).

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 gateways and might take a different route. It is not possible to determine in advance which ways these packets will take. At the receiving end the packets are checked and reassembled.

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 bandwidth needed is deployed on several packets sent on different routes. Detailed information about routing in the Internet can be obtained at http://www.scit.wlv.ac.uk/~jphb/comms/iproute.html.

One of the Internet's (and of the Matrix's) beginnings was the ARPANet, whose design was intended to withstand any disruption, as for example in military attacks. The ARPANet was able to route data around damaged areas, so that the disruption would not impede communication. This design, whith its origin in strategic and military considerations, remained unchanged for the Internet. Yet the design of the ARPANet's design cannot be completely applied to the Internet.

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 copyright and related rights in the information society. The proposed Directive aims at transposing into Community law the main international obligations arising from the two treaties on copyright and related rights adopted within the framework of the WIPO in December 1996 (WIPO Performances and Phonogram Treaty and WIPO Copyright Treaty). It applies to provisions relating to:

- the legal protection of computer programs

- rental right, lending right and certain rights related to copyright in the field of intellectual property

- 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): http://www.europa.eu.int/comm/internal_market/en/intprop/intprop/docs/index.htm

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 conditional access technology apply only for content with an exclusive right. If the content is already in the public domain, then there can be no possible violation of copyright law just from gaining access to it.

Transistor

A transistor is a solid-state device for amplifying, controlling, and generating electrical signals. Transistors are used in a wide array of electronic equipment, ranging from pocket calculators and radios to industrial robots and communications satellites.

Machine language

Initially computer programmers had to write instructions in machine language. This coded language, which can be understood and executed directly by the computer without conversion or translation, consists of binary digits representing operation codes and memory addresses. Because it is made up of strings of 1s and 0s, machine language is difficult for humans to use.
