As information systems enabled more diverse human activities, they exerted a profound influence over society. performance. One of the first computers used for such information processing was the UNIVAC I, installed at the U.S. Bureau of the Census in 1951 for administrative use and at General Electric in 1954 for commercial use. Sensors are becoming ever more widely distributed throughout the physical and biological environment to gather data and, in many cases, to effect control via devices known as actuators. This information system model highlights the relationships among the components and activities of information systems. The initial concept of MIS was to process the data available in the organization and present it in the form of reports at regular intervals.
