Internet, Intranets, Extranets, and Virtual Private Networks With the rise of networks and the corresponding decline of mainframe services computers have become communication devices instead of being solely computational or typewriter-like devices. Corporate networks become increasingly important and often use the Internet as a public service network to interconnect. Sometimes they are proprietary networks. Software companies, consulting agencies, and journalists serving their interests make some further differences by splitting up the easily understandable term "proprietary networks" into terms to be explained and speak of Intranets, Extranets, and Virtual Private Networks. Cable TV networks and online services as Europe Online, America Online, and Microsoft Network are also proprietary networks. Although their services resemble Internet services, they offer an alternative telecommunication infrastructure with access to Internet services for their subscribers. America Online is selling its service under the slogan "We organize the Web for you!" Such promises are more frightening than promising because "organizing" is increasingly equated with "filtering" of seemingly objectionable messages and "rating" of content.

Especially for financial transactions, secure proprietary networks become increasingly important. When you transfer funds from your banking account to an account in another country, it is done through the SWIFT network, the network of the Society for Worldwide Interbank Financial Telecommunication (SWIFT). According to SWIFT, in 1998 the average daily value of payments messages was estimated to be above U$ 2 trillion. Electronic Communications Networks as Instinet force stock exchanges to redefine their positions in trading of equities. They offer faster trading at reduced costs and better prices on trades for brokers and institutional investors as mutual funds and pension funds. Last, but not least clients are not restricted to trading hours and can trade anonymously and directly, thereby bypassing stock exchanges.

Legal Protection: TRIPS (Trade-Related Aspects of Intellectual Property Rights) Another important multilateral treaty concerned with intellectual property rights is the TRIPS agreement, which was devised at the inauguration of the Uruguay Round negotiations of the WTO in January 1995. It sets minimum standards for the national protection of intellectual property rights and procedures as well as remedies for their enforcement (enforcement measures include the potential for trade sanctions against non-complying WTO members). The TRIPS agreement has been widely criticized for its stipulation that biological organisms be subject to intellectual property protection. In 1999, 44 nations considered it appropriate to treat plant varieties as intellectual property. The complete TRIPS agreement can be found on: http://www.wto.org/english/tratop_e/trips_e/t_agm1_e.htm

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.

David Kahn David Kahn can be considered one of the most important historians on cryptography. His book The Codebreakers. The comprehensive history of secret Communication from Ancient Times to the Internet, written in 1996 is supposed to be the most important work on the history of cryptography.
