Tóm tắt : | This book is divided into five parts. Part 1, introduces the computer as a business tool from the macro point of the view: provides a general introduction, and then explains how business systems work, how computer systems work, and how the worlds of business and computers fuse together as computer-based information systems. Part 2 starts with how to use some prominent commercial software in world processing, spreadsheets, data base management, graphics, communications, and integrated packages, including application software development and programming languages. Part 3 covers input and output devices, CPU and operating systems, external storage and file organization, data base management systems, and networks and data communication systems. Part 4 covers systems analysis, systems design, transaction processing information systems, management information systems, decision support systems, and artificial intelligence and expert systems. Part 5 addresses some top concerns about the use of computers in our time: * describes the evolution of information systems, the importance of information resource management, and the possible course of computer-based information systems in the future, * covers privacy, security, and legal issues, * describes some of the risks in computer technology, including the problems of automation and employment.
