Introduces this issue, which contains papers from the 1991 Data Compression Conference, and defines data compression. The two primary functions of data compression are described, i.e., storage and communications; types of data using compression technology are discussed; compression methods are explained; and current areas of research are…

This thesis describes the requirements for a buffer storage device, with respect to other system components and its own limitations, which is designed to aid in the economic transmission of processed data from a central computer to distant terminals. Proceeding from the fact that tariff rates on wide band educational television channels are…

Describes new microcomputer software and hardware which simplify data communications between computer systems. "Dumb" terminal software, programs which enhance a computer's data communications flexibility by means of character translation and data buffering, stand-alone versus integrated systems, and "smart" modems are…

Considers the implications of possible policy initiatives in the United States in light of Swedish experience in dealing with the privacy of computerized records. (CWM)

Describes three stages of the automation of information processing systems by combining the concept of the exponential growth of operational capabilities with three characteristics: computational capability, ability to store data, and ability to communicate data. The growth of fiberoptic technology is described as beginning the third stage. (EM)

Presents a four-stage hypothesis of information systems development based on computational capability, storage capability, communications capability, and effective voice input. Moore's Law and Mooers' Law are explained, the interface between the system and the user is discussed, and projections for the future are suggested. (21 references)…

The Instructional Management System (IMS) developed by the Southwest Regional Laboratory (SWRL) processes student and teacher-generated data through the use of an optical scanner that produces a magnetic tape (Scan Tape) for input to IMS. A series of computer routines, OPSN, preprocesses the Scan Tape and prepares the data for transmission to the…

Outlines the technological evolution and the use of computers and telecommunications in information transactions and data storage. (CWM)

This paper describes some of the advances in telecommunications technology that can be anticipated during the 1980's in the areas of computer and component technologies, computer influences on telecommunications systems and services, communications terminals, transmission and switching systems, and local distribution. Specific topics covered…

The Southwest Regional Laboratory's Instructional Management System (IMS) central data processing system produces reports for dissemination to participating schools which provided the original source data to the system. Described in this document are the computer software routines (SIMS) that control the dissemination of information contained on…

A primer on information science introduces the study of how information is transmitted to the person who needs it and how it is later stored and retrieved. Beginning with the history of information as it was used by early man, the booklet summarizes the rapid development of new information technologies, with illustrations and in terms that can be…

A ten-year research study designed a mechanized information system in the information processing field. Special attention was paid to implementation criteria entering into on-line retrieval through man-machine dialog from a remote typewriter or video terminal and four major areas were investigated: search strategies, machine stored indexer aids,…
