Discusses the pricing of computer services. (PF)

Technology that once involved a scary, mysterious machine the size of a small house now fits on desktops and commonly appears in offices, schools, and homes. Computers allow for processing, storing and transmitting data between two or more people virtually anywhere in the world. They also allow users to save documents, presentations, photos and…

Discussion of factors that influence a publisher's choice of electronic and media delivery techniques; assesses use of diskettes, Bernoulli removable cartridge disks, CD-ROM, modems using dial-up phone lines, leased phone lines, satellites, and FM subcarriers. Sample data sizings are evaluated, and a cost model of electronic delivery costs is…

Briefly discusses the functions of microcomputer storage devices, printers, plotters, modems, speech devices, light pens, and touch panels. Capabilities of peripherals in various price ranges are compared to assist the personal computer owner in selecting devices appropriate to his needs. (MBR)

Describes the optical digital disk, which stores machine-readable information in digitized form, and discusses their production, cost, present and future applications. The major companies currently active in the disk field are noted. (MBR)

Describes the costs, programing languages, limitations, and capabilities of micro, mini, and mainframe computers, as well as specific computer projects and storage techniques, including disks, floppies, and videodiscs. Also discussed are links, networks, and computer features for libraries. A glossary and 22 references are provided. (RBF)

This discussion of the Integrated Services Digital Network (ISDN) telecommunications system compares it to existing telephone networks and describes international efforts at standardization, proposed services to business and residential customers, technological developments, and cost considerations. The effects of ISDN developments on the role of…

This continuation of the previously published four part directory reports information on several additional laserdisk databases and provides updates on some of those included in the original listing. Included in the product descriptions are producers; compatibility; type of laserdisk; software; interface with magnetic media; conditions of usage;…

Reviews terminology inherent in discussing microcomputer storage technologies and addresses aspects of magnetic storage and present and near-future technologies, including floppy disks, Winchester and removable hard disks, optical digital disks, optical video disks, (audio) compact disks, perpendicular magnetic recording, and erasable optical…

Discusses ranking techniques for document retrieval and proposes an evaluation, or filtering, technique that reduces costs and memory usage by early recognition of which documents are likely to be highly ranked. Highlights include index design, ranked query evaluation, reducing the number of accumulators, inverted file structures, and experimental…

Discusses major features of microcomputers (word length, memory, size, disk size and capacity, central processing unit speed, peripherals, software) and provides descriptions of 19 models. Comparative analysis on basis of cost, software support, machine capacity, storage capacity, and types of peripherals is presented. A 173-item bibliography is…

Explains the basic hardware, software, and media options for changing from a CD-ROM user to a CD-ROM publisher. Highlights include system configurations; computer recommendations; transfer media, including tapes, discs, and optical media; backup software and formatting/simulation software; costs; and publishing systems. (LRW)

Discusses factors converging to create high-capacity, low-cost nature of next generation of microcomputers: a coherent vision of what graphics workstation and future computing environment should be like; hardware developments leading to greater storage capacity at lower costs; and development of software and expertise to exploit computing power…

Describes the advantages of videodisc technology for storing vast amounts of information and discusses two applications--manual and catalog storage by the manufacturing industry and quick information access by medical and legal professionals. Future videodisc projects and a cost/performance comparison of videodiscs and other information storage…

Focusing primarily on hard disks, this report describes the choices currently available; explains the inner workings of hard-disk technology; lists 70 leading hard-disk products with their costs and capabilities; describes a new type of high-capacity drive; and compares speed, cost, and reliability of a number of widely used hard-disk backup…
