Discusses basic features and functions of spreadsheet programs and describes additional capabilities (editing, windowing, graphics, and word processing) of two second-generation spreadsheet programs: Lotus 1-2-3 and Symphony. (MBR)

Discussion of the factors that should be considered when purchasing or upgrading a microcomputer focuses on the MS-DOS and OS/2 operating systems. Macintosh purchasing decisions are discussed in a sidebar. A glossary is provided. (CLB)

Describes and evaluates the hardware, software, peripheral devices, performance capabilities, and programing capacity of the Sinclair ZX Spectrum microcomputer. The computer's display system, its version of the BASIC programing language, its graphics capabilities, and the unique features of its data entry keyboard are discussed. (JL)

Discusses the major categories of add-on microcomputer equipment--memory, mass storage, printers, plotters, monitors, modems, music and voice synthesizers, light pens, game controllers, graphics tablets, word processors, graphics packages, and furniture--and offers suggestions that may be helpful in making purchasing decisions. (MBR)

Reviews the current status of satellite remote sensing data, including problems with efficient storage and rapid retrieval of the data, and appropriate computer graphics to process images. Areas of research concerned with overcoming these problems are described. (16 references) (CLB)

Intended to enable educators to make intelligent decisions when purchasing hardware and software, this article presents basic information on computer hardware, effective software, and necessary peripherals needed to achieve educational objectives instructors have set. (MBR)

Provides basic information on videodisks and potential applications, including inexpensive online storage, random access graphics to complement online information systems, hybrid network architectures, office automation systems, and archival storage. (JN)

Reports on the state of currently available digital storage and retrieval systems and describes in detail one-sided optical videodisc LaserData and the Mnemos system, which stores graphic images on microfiche discs. Video Patsearch, Matrox, Philips Megadoc, DEMAND, and Digital Recording Corporation's optical digital records and future videodisc…

Describes software for displaying documents on computer graphics screens which provide the opportunity for interactive user interfaces. Based on a software system called Guide, this new approach relies on advances in hardware, such as the CD ROM, and can be used in the front end of a document retrieval system. (Author/LRW)

Discusses three new advances in the use of optical disc technology in education. Describes the storage formats and capabilities of the videodisc, the compact disc, and the optical write-once disc. Contrasts the three technologies in terms of their production requirements, the hardware involved, and some projected applications in education. (TW)

Presents response to a survey in the March and May 1982 issues of the American Association of Physics Teachers "Announcer" on microcomputer use by physics instructors. Provides background information on microcomputers useful in determining choice of system components, including applications development. Appendices give information on machine and…

This discussion of the use of images in learning processes focuses on recent developments in optical storage disc technology, particularly compact disc read-only (CD-ROM) and optical video discs. Interactive video systems and user interfaces are described, and applications in education and industry in the United Kingdom are reviewed. (Author/LRW)

This special feature focuses on recent developments in optical disk technology. Nine articles discuss current trends, large scale image processing, data structures for optical disks, the use of computer simulators to create optical disks, videodisk use in training, interactive audio video systems, impacts on federal information policy, and…

Centers on the current interest of using CD-ROM for text retrieval. Describes the digital video interactive (DVI) system which integrates graphics, audio, and video images with text. Explores why CD-ROM use by scientists is limited. (MVL)
