Global Data Flows In the space of flows constituted by today's global data networks the space of places is transcended. Visualizations of these global data flows show arches bridging seas and continents, thereby linking the world's centres of research and development, economics and politics. In the global "Network Society" (Manuel Castells) the traditional centres of power and domination are not discarded, in the opposite, they are strengthened and reinforced by the use of information and communication technologies. Political, economical and symbolical power becomes increasingly linked to the use of modern information and communication technologies. The most sensitive and advanced centres of information and communication technologies are the stock markets. Excluded from the network constituted by modern information and communication technologies, large parts of Africa, Asia and South America, but also the poor of industrialized countries, are ranking increasingly marginal to the world economy. Cities are centres of communications, trade and power. The higher the percentage of urban population, the more it is likely that the telecommunications infrastructure is generally good to excellent. This goes hand in hand with lower telecommunications costs. Those parts of the world with the poorest infrastructure are also the world's poorhouse. In Bangladesh for most parts of the population a personal computer is as expensive as a limousine in European one-month's salary in Europe, they have to pay eight annual salaries. Therefore telecommunications infrastructure is concentrated on the highly industrialized world: Most telephone mainlines, mobile telephones, computers, Internet accounts and Internet hosts (computers connected to the global data networks) can be found here. The same applies to media: the daily circulation of newspapers and the use of TV sets and radios. - Telecommunication and media services affordable to most parts of the population are mostly restricted to industrialized countries. This situation will not change in the foreseeable future: Most expenditure for telecommunications infrastructure will be restricted to the richest countries in the world. In 1998, the world's richest countries consumed 75% of all cables and wires. |

Punch card, 1801 Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, the punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology for processing statistical data retrieved from the US census in 1890, thus speeding up data analysis from eight to three years. His application of Jacquard's invention was also used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone applied them as a medium for the preparation, storage, and transmission of data for the first time. By their means, telegraph messages could be prepared off-line, sent ten times quicker (up to 400 words per minute), and stored. Later similar paper tapes were used for programming computers. |
