Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Defines in general terms the nature of computers, describes the various types of computers, discusses the characteristics and applications of the types of computers mentioned, reviews some basic facts about computer technology and computer hardware, and outlines a set of options for libraries considering acquiring a computer system.

The author describes the floppy disk with an analogy to the phonograph record, and discusses the advantages, disadvantages, and capabilities of hard-sectored and soft-sectored floppy disks. She concludes that, at present, the floppy disk will continue to be the primary choice of personal computer manufacturers and their customers. (KC)

Paper presented at the Annual National Conference on Linguistics (11th, New York, New York March 1966). First published in the BULLETIN OF PROSTHETICS RESEARCH.

A bulk data input processor which is available for the Rapidly Extensible Language (REL) English versions is described. In REL English versions, statements that declare names of data items and their interrelationships normally are lines from a terminal or cards in a batch input stream. These statements provide a convenient means of declaring some…

Discusses trends in computer technology and their use for library catalogs, noting the concept of bandwidth (describes quantity of information transmitted per given unit of time); computer hardware differences (micros, minis, maxis); distributed processing systems and databases; optical disk storage; networks; transmission media; and terminals.…

This manual was designed to provide the library manager or supervisor with a basic understanding of microcomputer hardware, software, procurement, and supervision. While developed for a summer workshop series, it can also serve as an introductory text. Separate chapters cover 10 major topics: (1) the microtechnology revolution; (2) how a…

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…

Reviews recent technological advances and developments relating to input devices, storage devices, output/display devices, and multimedia systems. Actual and possible applications of these technologies in the library, publishing, and information environments are discussed. (24 references) (CLB)

Project IMPACT (Instructional Model Prototypes Attainable in Computerized Training) is a comprehensive advanced development project designed to produce an effective and economical computer-administered instruction (CAI) system for the Army. The computer hardware and software capabilities of the prototype system are described. The components of the…

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

This article describes a number of problems every educational measurement specialist should be prepared to confront before using microcomputers to support test-related activities, including problems with hardware, with software, and with implementing a system. It concludes with a checklist for planning a microcomputer application. (BW)

Within the context of a large computer-based instructional system (CBI), the Air Forces Advanced Instructional System, instructional needs and requirements are evaluated as determinants of computer terminal design. It is shown that traditional definitions and uses of computer managed instruction (CMI) and computer assisted instruction (CAI) must…

The first of two articles discusses the technical issues of text transfer and processing encountered by the Knowledge Warehouse project. The second describes the development of the concept of a national electronic archive, and discusses issues such as contractual agreements, access control, copyrights, and commercial aspects of value added…

This paper is primarily an annotated listing of criteria for selection of a microcomputer to be used for online information retrieval. The paper was used by the University Library of the Technische Universitat Wien (Vienna, Austria) while preparing to contact computer dealers and to inform them about the library's needs in this specialized area of…
