A wide range of computer crimes and the need for computer security are discussed. (MK)

The Canadian Department of Education developed this manual to provide teachers and administrators with information about the potential use of computers. Part I describes at length the five components of the computer input, output, storage, control, and arithmetic/logic functions) and gives a discussion of computer languages, programing, batch…

The paper descibes a compact and highly efficient disk file management system responsible for the management and allocation of space on moving head disk drives in a medium-scale time-sharing system. The disk file management system is a major component of the Experimental Time-Sharing System (ETSS) developed at the Learning Research and Development…

Describes the components and the capabilities of nine minicomputers and how they are capable of serving as a terminal with remote IBM 360 or 370 computers. (MLF)

Designed to help the correctional administrator meet external demands for information, this detailed analysis of the demand information problem identifies the sources of requests for and the nature of the information required from correctional institutions and discusses the kinds of analytic capabilities required to satisfy most demand information…

A description is provided for WISE-ONE, an information retrieval program designed to provide fast, efficient access to computer-based information files. The author focuses upon WISE-ONE's application to the Educational Resources Information Center's (ERIC) data base; WISE-ONE was designed specifically to meet the needs of researchers using ERIC,…

Surveys the technology of database software and hardware, describing some of the principal issues related to the user's view of data, sharing, concurrent access, security, and integrity. (JN)

Discusses a few possibilities that computer-assisted learning holds for the problems of learning music. (Author/RK)

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

Past problems encountered in the use of computers are discussed. They include: (1) computing and data storage costs; (2) machine speed and capacity limitations; and (3) the limited number of languages and Input/Output devices available to facilitate man/machine communication. The improvements in all of these areas are explained. The problems which…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

This basic introduction to microcomputers provides the neophyte with the terminology, definitions, and concepts that explain the microcomputer and computing technology in general. Mathematical operations with binary numbers, computer storage, controlling logic, and the concepts of stack and interrupt are explained. (RAO)

The computational complexity of a formal process for the construction of term classes for information retrieval is examined. While the process is proven to be difficult computationally, heuristic methods are applied. Experimental results are obtained to illustrate the maximum possible improvement in system performance of retrieval using the formal…

This book offers the career-minded young reader insight into computers and computer-programming, by describing the nature of the work, the actual workings of the machines, the language of computers, their history, and their far-reading and increasing applications in business, industry, science, education, defense, and government. At the same time,…

Describes several microcomputer systems developed for training purposes. Explains how the lower costs and expanded capability and availablilty of the microcomputer can be used by business for employee training and by schools in the classrooms. Includes information on computer programs and memory storage. (MF)
