A network of regional computer processing sites will establish a path for small school districts to access the facilities at a larger computer site. Networking between sites greatly enhances a user's--and consequently his local district's--computing resources. (Author/MLF)

A constantly expanding, vast network of telecommunication links spans the industrialized countries of the world, carrying telephone, telegraph, and television signals, news photographs, and radio programs. The field of data transmission through these links is covered in this book, which first offers a brief rationale and discussion of various…

Texas provides computer service to public school districts through 20 Regional Education Service Centers. (Author/MLF)

Describes a system for payroll reporting from geographically disparate locations in which data is entered, edited, and verified locally on minicomputers and then uploaded to a central computer for the standard payroll process. Communications and hardware, time-reporting software, data input techniques, system implementation, and its advantages are…

Current developments in an experiment on Computer Communications via the ATS-1 geosynchronous satellite are described. Initiated by the Spacecraft Data Systems Branch of the Ames Research Center, NASA, this experiment is designed to demonstrate the feasibility of utilizing satellite communication links to provide computer-computer and…

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…

During the 1971-72 pilot test of the Southwest Regional Laboratory's (SWRL) Instructional Management System (IMS), three alternative procedures were used to gather data within the classroom, transmit those data to SWRL for processing, and send IMS output to the appropriate recipients in the schools. ComSys 3--one of the three…

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…

The new data retrieval system for the social sciences which has recently been installed in the UNESCO Secretariat in Paris is described in this comprehensive report. The computerized system is designed to facilitate the existing storage systems in the circulation of information, data retrieval, and indexing services. Basically, this report…

Progress on the development of a mathematical model and associated computer programs for use by the Illinois State Library in evaluation and planning of the interlibrary loan (ILL) network is summarized. Pertinent published literature on ILL networks is reviewed in terms of network structure, operations, satisfaction of requests, and costs. A flow…

Five considerations of a comprehensive configuration to carry out computer-based instructional management are described. Included are data communications networks, loading/distribution of data processing operations and Instructional Management System functions, response time, computer software, and flexibility. The need for such a configuration is…

The MERIT Computer Network interconnects computing systems of three large universities: The University of Michigan, Michigan State University, and Wayne State University. This telecommunication system facilitates the sharing of computing resources among students, faculty, and research staffs of those institutions. The present document provides an…

Measures, tools, and techniques applicable to the performance measurement of computer communication networks are described for technicians who procure computer services from a remote access network. Cost considerations are discussed as a major component of evaluation, and measurement and evaluation methodologies are surveyed. External measurement…
