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.

History: "The South"

In many traditional Southern countries awe and mystery surround the created object into which the creator projects spirit and soul. Also in contrast with the Western individual-based concept of intellectual property rights it is custom to recognize 'collective', 'communal' or 'folkloric' copyright. Folkloric copyright acknowledges rights to all kinds of knowledge, ideas and innovations produced in 'intellectual commons'. Such rights are not limited to the lifetime of an individual but rather exist in perpetuity with a specific group or an entire people.

Islamic Tradition

Already early Islamic jurists recognized a creator's right or copyright and offered protection against piracy. Traditional Islamic law treats infringement as a breach of ethics, not as a criminal act of theft. Punishment is carried out in the form of defamation of the infringer and the casting of shame on his tribe. Only in recent years many Islamic countries have adopted formal copyright statutes.

John von Neumann

b. December 3, 1903, Budapest, Hungary
d. February 8, 1957, Washington, D.C., U.S.

Mathematician who made important contributions in quantum physics, logic, meteorology, and computer science. His theory of games had a significant influence upon economics. In computer theory, von Neumann did much of the pioneering work in logical design, in the problem of obtaining reliable answers from a machine with unreliable components, the function of "memory," machine imitation of "randomness," and the problem of constructing automata that can reproduce their own kind.

Vacuum tube

The first half of the 20th century was the era of the vacuum tube in electronics. This variety of electron tube permitted the development of radio broadcasting, long-distance telephony, television, and the first electronic digital computers. These early electronic computers were, in fact, the largest vacuum-tube systems ever built. Perhaps the best-known representative is the ENIAC (Electronic Numerical Integrator and Computer, completed in 1946).

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 writing and calculating, administrative purposes account for the beginning of modern automatic data processing.

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.

UNIVAC

Built by Remington Rand in 1951 the UNIVAC I (Universal Automatic Computer) was one of the first commercially available computers to take advantage of the development of the central processing unit (CPU). Both the U.S. Census bureau and General Electric owned UNIVACs. Speed: 1,905 operations per second; input/output: magnetic tape, unityper, printer; memory size: 1,000 12-digit words in delay line; technology: serial vacuum tubes, delay lines, magnetic tape; floor space: 943 cubic feet; cost: F.O.B. factory U.S.$ 750,000 plus U.S.$ 185,000 for a high speed printer.
