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.

No mass-media is more efficient in disinformation and propaganda than TV. And no one seems to be better in influencing that which is considered the truth. e.g. around 67% of the Austrian population in 1999 believe that TV is the most reliable information-media.
Opinion polls show that it is said to be the most realistic media, the only one worth trusting. History tells us the contrary. The combination of words and moving pictures, together with the documentary style of the news, looks sincere, while it produces images in our heads which start working on their own. The Vietnam war was only the first war performed on television ...
But: also watching the news is part of the entertainment show of the media. And therefore they are presented in an entertaining form. Manipulation of the contents of the news is part of the show.
One factor is the issue that news must be reported in a very short period. Several seconds for each catastrophe. Scarcity implies disinformation.
Ted Koppel's movie Revolution in a box demonstrates this:
When the TV-news showed pictures of the nuclear plant accident in Chernobyl, they showed pictures of another - still working - plant. The thought behind was to demonstrate that in this world nothing can stay undetected by the media, to show that still everything is observed and under control - at least in the West.

While most progressive think tanks acquire their funding through many different sources, for conservative think tanks financing by corporations prevails. Among the think tanks receiving a considerable amount of corporate money are the Cato Institute (U.S. conservative/libertarian), the Brookings Institution (U.S. centrist), the Heritage Foundation (U.S. conservative), the American Enterprise Institute (U.S. conservative) and the
Also, whereas the combined revenue base of such conservative multi-issue policy institutions as the Heritage Foundation, the American Enterprise Institute, Free Congress Research and Education Foundation, the Cato Institute, and

Established in 1950, the National Science Foundation is an independent agency of the U.S. government dedicated to the funding in basic research and education in a wide range of sciences and in mathematics and engineering. Today, the NSF supplies about one quarter of total federal support of basic scientific research at academic institutions.
