The Mini-Computer is compared with the general purpose computer. On a performance basis the Mini-Computer shows several interesting comparisons with the System 360 computer. The Mini-Computer core cycle, instruction execution speeds, and disc operating speeds are quite similar to the much larger 360-30 and 40 while its magnetic tape speeds are…

Describes how Ohio University devised computer forms that would coordinate the requirements of the university, minimize the problems of students in completing the forms, and meet the specifications of its data processing equipment. (JF)

The subject of access control mechanisms in computer systems is concerned with effective means to protect the anonymity of private information on the one hand, and to regulate the access to shareable information on the other hand. Effective means for access control may be considered on three levels: memory, process and logical. This report is a…

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

Introduces some algorithmic methods, for which no pre-editing is necessary, for automatically "lemmatising" raw text (changing raw text to an equivalent version in which all inflected words are artificially transformed to their dictionary look-up form). The results of a study of these methods, which used a German Text, are also given. (KM)

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,…

Described are types of programs used for processing text (editors, print formatters, and word processors), followed by the comparison of four word-processing packages: Auto Scribe, Electric Pencil, Magic Want and Word Star. With the exception of Auto Scribe, all programs reviewed are CP/M versions. (KC)

Computer data on the technical level of devices, their speed rates, and computer languages of two Oakland County Michigan area centers' business data processing skill programs are discussed to provide information for other area centers on various hardware, software, and teachware. (BP)

AREAS INVESTIGATED INCLUDE SLOW MEMORY DATA STORAGE, THE PROBLEM OF DECODING FROM AN INDEX TO A SLOW MEMORY ADDRESS, THE STRUCTURE OF DATA LISTS AND DATA LIST OPERATORS, COMMUNICATIONS BETWEEN THE HUMAN USER AND THE SYSTEM, PROCESSING OF RETRIEVAL REQUESTS, AND THE USER'S CONTROL OVER THE RETURN OF INFORMATION RETRIEVED. LINEAR, LINKED AND…

This paper describes a locally-developed multi-purpose system that stores data about any number of special collections within the libraries and prints that data in a number of formats on demand or as scheduled reports. The system operates on an IBM 360/67 dual processer with data entry via a teleprocessing system. The key to the file is the call…

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

The report specifies the design of the data entry system for the Sample Data System subsystems (SDS-1 and SDS-2) providing connectability to meet previously specified purposes and functions of the Management Information System for Occupational Education (MISOE). General assumptions for specifying the SDS data entry system are stated including the…

The report describes the Classroom Information and Computing Service (CLICS), a pedagogical computer-based information system that is used as a case study in the subject "Information Systems" in the Dept. of Electrical Engineering at M.I.T. CLICS is an abstraction of the Multiplexed Information and Computing Service (MULTICS) that is being…

A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…

Teacher background information and student materials are provided in this guide for teaching a one-semester data processing course, which may be used with or without microcomputer equipment. The material is organized into eight units covering history and evolution of data processing, information processing today, input/output media and devices,…
