After presenting a basic introduction to computers, computer terminology, computer languages, history, concepts of organizational management, and applications of computers in criminal justice administration, the discussion turns to data-based information management applications. The concepts of data base management and management information systems are introduced, followed by an examination of microcomputer technology (hardware and software) applications in relation to the administrative functions of planning, budgeting, and fiscal and resource management. Key problems in bureaucratic management communications in criminal justice agencies and institutions are identified, followed by a discussion of computer-assisted writing applications in management communications. Also considered are selected theoretical and applied aspects of information networking and its potential ramifications in criminal justice management. Computer-assisted instruction, which places the student in a conversational mode with a computer preprogrammed with a study plan, is considered, with attention to demonstrated and potential applications in criminal justice training and education. The text concludes with a discussion of emerging criminal justice issues in computer technology. About 150 bibliographic listings are provided along with a glossary of selected terms and a subject index.
