Reviews computer storage devices designed to provide additional memory for microcomputers--chips, floppy disks, hard disks, optical disks--and describes how secondary storage is used (file transfer, formatting, ingredients of incompatibility); disk/controller/software triplet; magnetic tape backup; storage volatility; disk emulator; and…

Describes computer operating systems applicable to microcomputers, noting hardware components, advantages and disadvantages of each system, local area networks, distributed processing, and a fully configured system. Lists of hardware components (disk drives, solid state disk emulators, input/output and memory components, and processors) and…

The Tarrytown Technical Information Center at General Foods produces report style searches by using upgraded equipment which allows search strategies to be stored and edited offline, thus reducing costs for both online searching and for the searcher's time. A computer program for eliminating duplicate bibliographic citations is included. (RBF)

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…

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.…

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 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…

This article defines three separate categories of microcomputers--personal, desk-top, multi-user devices--and relates storage capabilities (expandability, floppy disks) to library applications. Highlghts include de facto standards, operating systems, database management systems, applications software, circulation control systems, dumb and…

WISE is an on-line interactive information retrieval system designed particularly for bibliographic data bases, but it is potentially useful for any keyword-oriented data base. The WISE user searches a data base by entering and combining keywords that are appropriate to the data base and the subject area of interest. The user can also enter…
