Late 1970s - Present: Fourth Generation Computers Following the invention of the first integrated circuits always more and more components could be fitted onto one chip. LSI (Large Scale Integration) was followed by VLSI (Very Large Scale Integration) and ULSI (Ultra-Large Scale Integration), which increased the number of components squeezed onto one chip into the millions and helped diminish the size as well as the price of computers. The new chips took the idea of the integrated circuit one step further as they allowed to manufacture one microprocessor which could then be programmed to meet any number of demands. Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used. Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations. LANs (Local Area Network) permitted computers to share memory space, information, software and communicate with each other. Although already LANs could reach enormous proportions with the invention of the Internet an information and communication-network on a global basis was established for the first time.

The Cassini Case In 1997 NASA's Cassini mission to Saturn and its moons led to heated controversies, because it was fueled by plutonium, a substance that could cause serious environmental and health problems if it were released into the atmosphere. Still no major U.S. news outlet in broadcasting or print reported in depth on the risks of the Cassini mission. Westinghouse-owned media like CBS and NBC (also partly owned by General Electric) for example had only reported that children were invited to sign a plaque inside Cassini. Not surprisingly Westinghouse and General Electric are two of the largest corporations with defense contracts and nuclear interests.

Institute for Global Communications (IGC) IGC's vision is to actively promote change toward a healthy society, which is founded on the principals of social justice, broadly shared economic opportunity, a robust democratic process, and sustainable environmental practices. IGC believes that healthy societies rely fundamentally on respect for individual rights, the vitality of communities and diversity. IGC's aim is to advance the work of progressive organizations and individuals for peace justice economic opportunity, human rights, democracy and environmental sustainability through strategic use of online technologies. History In 1987 the Institute for Global Communications was officially formed to manage PeaceNet and the newly acquired EcoNet, which was the world's first computer network dedicated to environmental preservation and sustainability. In 1988 IGC began to collaborate with like-minded organizations outside the states and in partnership with six international organizations, IGC co-founded the Association of Progressive Communications (APC). ConflictNet, incorporated by IGC in 1989, to provide information and communications for people by promoting the constructive resolution of conflicts is now enfolded in the PeaceNet network. LaborNet, a full network of IGC from 1992 through August 1999, serves the labor community by working for the human rights and economic justice of workers. WomensNet, launched in 1995 is an online community of individuals and organizations who use computer technology to advance the interests of women worldwide. Also the Anti-racism.Net forms part of IGC network family. Strategies and Policies IGC's aim is to offer progressive individuals and groups a place on the Internet to learn, meet and organize. IGC focuses on content, information sharing and collaborative tools and provides Internet access services, e-mail discussions and newsletters. The Institute for Global Communications aims at bringing Internet tools and online services to organizations and activists working on peace, economic and social justice, human rights, environmental protection, labor issues and conflict resolution. IGC also provides alternative news and political analysis as well as information about other progressive organizations.

Sputnik At the beginning of the story of today's global data networks is the story of the development of satellite communication. In 1955 President Eisenhower announced the USA's intention to launch a satellite. But it was the Soviet Union, which launched the first satellite in 1957: Sputnik I. After Sputnik's launch it became evident that the Cold War was also a race for leadership in the application of state-of-the-art technology to defence. As the US Department of Defence encouraged the formation of high-tech companies, it laid the ground to Silicon Valley, the hot spot of the world's computer industry. In the same year the USA launched their first satellite - Explorer I - data were transmitted over regular phone circuits for the first time, thus laying the ground for today's global data networks. Today's satellites may record weather data, scan the planet with powerful cameras, offer global positioning and monitoring services, and relay high-speed data transmissions. But up to now, most satellites are designed for military purposes such as reconnaissance.

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.

Proxy Servers A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that security, administrative control, and caching service can be ensured. A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user. Source: Whatis.com
