Information IT Systems (IS): Tests with Answers

At the first stage of the use of information and computer technologies (ICT) (the 1950s-1960s) in economic research and for managing the economic activity of enterprises, data processing systems (Data Processing System - DPS) began to be used. With their help, it was possible to achieve the automation of paper document flow through the computerization of operations needed to process large volumes of economic information. The most widely used were, in particular, inventory management systems, payroll calculation systems, and invoicing systems. The second stage (the 1960s-1970s) was marked by the emergence of second-generation information systems (Management Information Systems – MIS), or management information systems. The operation of such systems was based on the creation of a database with a single control center, which was implemented using a special software product – a database management system. Thanks to this, the efficiency of enterprise management increased significantly. The third stage (the 1970s-1990s) was driven by the mass production of personal computers with a "friendly" interface and flexible software. In the field of economic management, decision support systems (Decision Support Systems – DSS) began to be used. Such systems were actively used in production, financial planning, marketing, and pricing. Work began on creating expert systems in business and management. New software emerged, designed to support the process of group decision making. The fourth, modern stage of ICT development (which began in the 1990s and continues to this day) is characterized by the emergence and development of Internet technologies and multimedia tools, and by the appearance of a virtual information space (virtual offices, organiz
