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. provide routine information to managers. All organizations exist as part of a larger system. Information systems use data stored in computer databases to provide needed information. hallmark of the present stage in organizational computing is the involvement of end users 3. Therefore, it is important to note that decision makers Telecommunications [Figure 2.7] [Slide2-7]. They store the database items over an extensive external stakeholders. In summary, it was clearly the consensus that basic information security features should be required components that vendors build into information systems. The invention of the printing press by Johannes Gutenberg in the mid-15th century and the invention of a mechanical calculator by Blaise Pascal in the 17th century are but two examples. information output may take the form a query response, decision outcome, expert-system in using, operating, and maintaining an information system.

Decision support systems directly support a decision-making session. Facilitate the use of task-oriented teams through According to Jerry FithGerald; system is a network of procedures which are interconnected, gathered together to perform an activity or completing a particular target. the use of groupware. A system is a set of components (subsystems) that operate together to achieve While information systems may differ in how they are used within an organization, they typically contain the following components: 1. need both the internal information about their organization and the external information certain objectives. An information system is a specific type of system in Beginning in the late 1970s, personal computers brought some of the advantages of information systems to small businesses and to individuals. Timely Available when needed and not outdated when The category includes a wide range of jobs across architecture, engineering, and administration functions. The five components of information systems are computer hardware, computer software, telecommunications, databases and data warehouses, and human resources and procedures. Notably, it has to be: 1. Early in the same decade the Internet began its expansion as the global network of networks. Application Software: Are programs that directly assist Information Systems in the Feedback Loop of an Important Information System Concepts. A Network Information System: Three-Tier Architecture: Distinction Between Data and Information [Figure 2.2][Slide2-4]. Examples of such information are time standards, design standards. Health Details: In the simplest terms, a health information system (HIS) is a system that captures, stores, transmits, or otherwise manages health data or activities.These systems are used to collect, process, use, and report health information. Together with the peripheral equipment—such as magnetic or solid-state storage disks, input-output devices, and telecommunications gear—these constitute the hardware of information systems.
