CAPSI ís a technological educational innovation with the combination of physical and behavioral technologies to produce an engineering approach to education. Unlike pSI, CAPSI adopts computer technology with a finite-state modelling implementation to free the instructor from administration, promote individualized learning, and provide tools for the analysis of the dynamical educational process and its optimization. Developed and extensively tested over the past five years at the university of Manitoba, CAPSI has gone through a natural evolution from a single terminal to multiple terminals, with direct. and remote links, and electronic mailing and messaging. CAPSI has been used successfully, effectively, and economically in short-distance (on campus) and longdistance (off campus) teaching, thus extending the fundamental concepts of education from a physical classroom to a virtual classroom and even to a virtual campus which eliminates the need for the instructor and the students to be at the sarne place and at the same time. -ll- ACKF{OWT,EDGEMENTS I would like to extend my sincere thanks and appreciation to Dr. Witold Kinsnet, fry advisor, for his supervision, teaching, assistance, Perseverance, and patience during the course of my research and also for his suggestions of more than one research topics. special thanks to Dr. ]oseph Pear and Dr. Kinsner who have contributed the main research ideas to the development of the CAPSI system. Also thanks go to Frank Herzog for the initial coding of the Program. In addition, thanks to Dr. ]. Poltz for his comment on this thesis. I would like to thank the financial support from the Industrial Applications of Microelectronics Centre Inc., the University of Manitoba Academic Development Fund, the Natural Sciences and Engineering Research Council of Canada, and private funds. The last but not least, I thank my parents and family for their financial and emotional support of my stay in Canada, and I finally acknowledge the Christian faith that carries me through difficulties and hardship. - 1r1- T^åBLE OF CO}üT'EF{T'S Pase ABSTRACT ii ACKNOWLEDGEMENTS iii LIST OF CONTENTS vi LIST OF FIGTIRES v11r +Chanter I.

  • An Interview With
    An Interview with WARREN PRINCE OH 413 Conducted by Jeffrey R. Yost on 4 April 2012 Computer Services Project Sunnyvale, California Charles Babbage Institute Center for the History of Information Technology University of Minnesota, Minneapolis Copyright, Charles Babbage Institute Warren Prince Interview 4 April 2012 Oral History 413 Abstract Warren Prince was an executive at Tymshare and served as the leader of TYMNET. He served on the management team at McDonnell Douglas after it acquired TYMNET. The interview concentrates on TYMNET’s history and explaining and providing context to some of the documents he provided for the interview. 2 Prince: So will you produce the chapter in your book out of audio? I’ve got a bunch of papers that might be of interest or might not. Yost: Terrific, I would. Prince: Because it kind of shows; first, on the TYMNET side it shows the growth of it and really, the initial problems of it, which graphically shows it instead of saying it. And then the McDonnell Douglas part. Anyway, we can get into that when the time comes. Yost: Sounds good. My name is Jeffrey Yost, from the Charles Babbage Institute at the University of Minnesota, and I’m here today on April 4th, 2012, with Warren Prince of Tymshare and TYMNET. I’d like to begin just with some brief biographical stuff. Could you tell me where you were born, where you grew up? Prince: Born in Walnut Creek, California but grew up mostly in Arizona; Glendale, Arizona. And went through; started at the University of Arizona, and then joined the Army.

This book provides in depth knowl- edge on telecommunication switching and good background for advanced studies in communi- cation networks. The entire subject is dealt with conceptual treatment and the analytical or mathematical approach is made only to some extent. For best understanding, more diagrams (202) and tables (35) are introduced wherever necessary in each chapter. The telecommunication switching is the fast growing field and enormous research and development are undertaken by various organizations and firms. The communication networks have unlimited research potentials. Both telecommunication switching and communication networks develop new techniques and technologies everyday. This book provides complete fun- damentals of all the topics it has focused. However, a candidate pursuing postgraduate course, doing research in these areas and the employees of telecom organizations should be in constant touch with latest technologies.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

Wunder, Jr., Assistant Secretary for Communications and Information June 1982 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Preface This report describes Integrated Services Digital Network (ISDN) concepts, status, and technologies. The ISDN is expected to be a major architectural concept in the future. Awareness of the ISDN by the military is important because the commercial sector is already be­ ginning to evolve in this direction on a national and international scale, and important new technologies are involved. This report is submitted as partial completion of a study being conducted for the U.S. Army's Communications Systems Agency at Ft. Monmouth, New Jersey, under project order number 105 RD. It is one of a series of reports on a multiphase project to analyze requirements and evaluate alternatives for the Defense Communications System in Europe. Administrative and technical monitoring of this pro­ ject was performed by Mr. R. Brynildsen of CSA. Technical and management supervision of the program at ITS was pro­ vided by Dr. P. M. McManamon and Mr. R. F. Linfield. Certain commercial names and companies are identified in this report to specify and describe some of the neces­ sary information.
