Information system, an integrated set of components for collecting, storing, processing, and communicating information. Business firms, other organizations, and individuals in contemporary society rely on information systems to manage their operations, compete in the marketplace, supply services, and augment personal lives. For instance, modern corporations rely on computerized information systems to process financial accounts and manage human resources; municipal government rely on information systems to provide basic services to its citizens; and individuals use information systems to study, shop, bank, and invest.

“As major new technologies for recording and processing information have been invented, new capabilities have appeared. The invention of movable type in the mid-15th century and the creation of the portable typewriter at the end of the 19th century are but two examples. Each of these inventions led to a profound revolution in the ability to record and disseminates information. The first large-scale mechanized information system was Herman Hollerith’s census tabulator. Invented to process the 1890 U.S. census, Hollerith’s machine represented a major step in automation, as well as an inspiration to develop computerized information systems. One of the first computers used for such information processing was the UNIVAC I, installed in the U.S. Bureau of the Census in 1951 for administrative use and in General Electric in 1954 for commercial use. Beginning in the 1970s, personal computers brought some of the advantages of information systems to small businesses and to individuals, and the invention of the World Wide Web in the early 1990s accelerated the creation of an open global computer network. This was acompanied by a dramatic growth in digital human communications (e-mail and electronic conferences), delivery of products (software, music, and movies), and business transactions (buying, selling, and advertising on the Web).”
