1940s - Early 1950s: First Generation Computers

Probably the most important contributor concerning the theoretical basis for the digital computers that were developed in the 1940s was Alan Turing, an English mathematician and logician. In 1936 he created the Turing machine, which was originally conceived as a mathematical tool that could infallibly recognize undecidable propositions. Although he instead proved that there cannot exist any universal method of determination, Turing's machine represented an idealized mathematical model that reduced the logical structure of any computing device to its essentials. His basic scheme of an input/output device, memory, and central processing unit became the basis for all subsequent digital computers.

The onset of the Second World War led to an increased funding for computer projects, which hastened technical progress, as governments sought to develop computers to exploit their potential strategic importance.

By 1941 the German engineer Konrad Zuse had developed a computer, the Z3, to design airplanes and missiles. Two years later the British completed a secret code-breaking computer called Colossus to decode German messages and by 1944 the Harvard engineer Howard H. Aiken had produced an all-electronic calculator, whose purpose was to create ballistic charts for the U.S. Navy.

Also spurred by the war the Electronic Numerical Integrator and Computer (ENIAC), a general-purpose computer, was produced by a partnership between the U.S. government and the University of Pennsylvania (1943). Consisting of 18.000 vacuum tubes, 70.000 resistors and 5 million soldered joints, the computer was such a massive piece of machinery (floor space: 1,000 square feet) that it consumed 160 kilowatts of electrical power, enough energy to dim lights in an entire section of a bigger town.

Concepts in computer design that remained central to computer engineering for the next 40 years were developed by the Hungarian-American mathematician John von Neumann in the mid-1940s. By 1945 he created the Electronic Discrete Variable Automatic Computer (EDVAC) with a memory to hold both a stored program as well as data. The key element of the Neumann architecture was the central processing unit (CPU), which allowed all computer functions to be coordinated through a single source. One of the first commercially available computers to take advantage of the development of the CPU was the UNIVAC I (1951). Both the U.S. Census bureau and General Electric owned UNIVACs (Universal Automatic Computer).

Characteristic for first generation computers was the fact, that instructions were made-to-order for the specific task for which the computer was to be used. Each computer had a different binary-coded program called a machine language that told it how to operate. Therefore computers were difficult to program and limited in versatility and speed. Another feature of early computers was that they used vacuum tubes and magnetic drums for storage.

Content as Transport Medium for Values and Ideologies

With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers.

With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back.

Global Data Flows

Fiber-optic cables, coaxial cables, copper wires, electric power lines, microwaves, satellite communication, mobile telephony, computer networks: Various telecommunication networks following a variety of standards with bewildering abbreviations - DSL, WAP, GSM, UMTS, Ipv4 etc. - and carrying endless flows of capital and information are the blood veins of modern societies.

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.

Artificial intelligence approaches

Looking for ways to create intelligent machines, the field of artificial intelligence (AI) has split into several different approaches based on the opinions about the most promising methods and theories. The two basic AI approaches are: bottom-up and top-down. The bottom-up theory suggests that the best way to achieve artificial intelligence is to build electronic replicas of the human brain's complex network of neurons (through neural networks and parallel computing) while the top-down approach attempts to mimic the brain's behavior with computer programs (for example expert systems).

WTO

An international organization designed to supervise and liberalize world trade. The WTO (World Trade Organization) is the successor to the General Agreement on Tariffs and Trade (GATT), which was created in 1947 and liberalized the world's trade over the next five decades. The WTO came into being on Jan. 1, 1995, with 104 countries as its founding members. The WTO is charged with policing member countries' adherence to all prior GATT agreements, including those of the last major GATT trade conference, the Uruguay Round (1986-94), at whose conclusion GATT had formally gone out of existence. The WTO is also responsible for negotiating and implementing new trade agreements. The WTO is governed by a Ministerial Conference, which meets every two years; a General Council, which implements the conference's policy decisions and is responsible for day-to-day administration; and a director-general, who is appointed by the Ministerial Conference. The WTO's headquarters are in Geneva, Switzerland.

Netiquette

Although referred to as a single body of rules, there is not just one Netiquette, but there are several, though overlapping largely. Proposing general guidelines for posting messages to newsgroups and mailing lists and using the World Wide Web and FTP, Netiquettes address civility topics (i.e., avoiding hate speech) and comprise technical advises (i.e., using simple and platform-independent file formats).
Well-known Netiquettes are the Request for Comment #1855 and The Net: User Guidelines and Netiquette by Arlene H. Rinaldi.
