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.

Division of labor The term refers to the separation of a work process into a number of tasks, with each task performed by a separate person or group of persons. It is most often applied to mass production systems, where it is one of the basic organizing principles of the assembly line. Breaking down work into simple, repetitive tasks eliminates unnecessary motion and limits the handling of tools and parts. The consequent reduction in production time and the ability to replace craftsmen with lower-paid, unskilled workers result in lower production costs and a less expensive final product. The Scottish economist Adam Smith saw in this splitting of tasks a key to economic progress by providing a cheaper and more efficient means of producing economic goods.
