The 19th Century: First Programmable Computing Devices

Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early calculators like the abacus worked with a system of sliding beads arranged on a rack and the centerpiece of Leibniz's multiplier was a stepped-drum gear design.

Therefore Charles Babbage's proposal of the Difference Engine (1822), which would have (it was never completed) a stored program and should perform calculations and print the results automatically, was a major breakthrough, as it for the first time suggested the automation of computers. The construction of the Difference Engine, which should perform differential equations, was inspired by Babbage's idea to apply the ability of machines to the needs of mathematics. Machines, he noted, were best at performing tasks repeatedly without mistakes, while mathematics often required the simple repetition of steps.

After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer.

The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed.

Of extraordinary importance for the evolution of digital computers and artificial intelligence have furthermore been the contributions of the English mathematician and logician George Boole. In his postulates concerning the Laws of Thought (1854) he started to theorize about the true/false nature of binary numbers. His principles make up what today is known as Boolean algebra, the collection of logic concerning AND, OR, NOT operands, on which computer switching theory and procedures are grounded. Boole also assumed that the human mind works according to these laws, it performs logical operations that could be reasoned. Ninety years later Boole's principles were applied to circuits, the blueprint for electronic computers, by Claude Shannon.

Positions Towards the Future of Copyright in the "Digital Age"

With the development of new transmission, distribution and publishing technologies and the increasing digitalization of information copyright has become the subject of vigorous debate. Among the variety of attitudes towards the future of traditional copyright protection two main tendencies can be identified:

Eliminate Copyright

Anti-copyrightists believe that any intellectual property should be in the public domain and available for all to use. "Information wants to be free" and copyright restricts people's possibilities concerning the utilization of digital content. An enforced copyright will lead to a further digital divide as copyright creates unjust monopolies in the basic commodity of the "information age". Also the increased ease of copying effectively obviates copyright, which is a relict of the past and should be expunged.

Enlarge Copyright

Realizing the growing economic importance of intellectual property, especially the holders of copyright (in particular the big publishing, distribution and other core copyright industries) - and therefore recipients of the royalties - adhere to the idea of enlarging copyright. In their view the basic foundation of copyright - the response to the need to provide protection to authors so as to give them an incentive to invest the time and effort required to produce creative works - is also relevant in a digital environment.

Transmission Control Protocol/Internet Protocol (TCP/IP)

TCP and IP are the two most important protocols and communication standards. TCP provides reliable message-transmission service; IP is the key protocol for specifying how packets are routed around the Internet.

Intellectual property

Intellectual property, very generally, relates to the output that result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) industrial property (inventions, marks, industrial designs, unfair competition and geographical indications), and 2) copyright. The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products.
