time-sharing-systems

This chapter outline from 'Man and the Computer' by John G. Kemeny presents a structured exploration of the evolving relationship between humans and computers, conceptualizing it as a symbiosis. It covers the historical emergence of computers as a new 'species,' their collaborative potential with humans, the development of time-sharing systems, and the societal implications of integrating computers into various domains such as education, libraries, management, and home life. The text also anticipates future developments and challenges in this symbiotic evolution.

The chapter recounts early experiences with scarce and expensive computers, highlighting the inefficiencies in access and the subsequent development of time-sharing systems to improve usability. It also describes the introduction of the FORTRAN programming language, which made computer programming more accessible to humans, and the acquisition of Dartmouth's first computer, the LGP-30, which provided students with hands-on experience. The author reflects on the dramatic advancements in computing power, memory, and cost efficiency over twenty-five years, emphasizing the exponential growth in capabilities and the reduction in computational costs.

This chapter discusses the transformative impact of time-sharing computer systems like DTSS on education, research, and recreation at Dartmouth. It highlights how students across disciplines use computers for complex problem-solving, research assistance, and engaging interactive games that simulate real-world scenarios. The chapter emphasizes the role of computers in breaking psychological barriers to technology use and fostering a new symbiotic relationship between humans and machines.

The chapter discusses the advantages and limitations of Computer-Assisted Instruction (CAI). It highlights the flexibility, error-free operation, and impersonal nature of computers as teaching aids, while critiquing CAI as an expensive substitute for books and a poor substitute for human teachers. The author emphasizes that CAI is most effective for rote learning and mechanical drills but struggles with anticipating diverse student responses and providing the nuanced feedback a human teacher can offer.

The chapter discusses the dual nature of computer technology, emphasizing its positive applications in business and education while cautioning against potential misuse, particularly in centralized information control. It highlights the versatility of general-purpose computers in handling both scientific and business tasks, illustrating how time-sharing systems enable simultaneous multi-purpose use. The author stresses the importance of maintaining diverse libraries to prevent the suppression of knowledge and advocates for oversight by a panel of experts rather than federal agencies.

The chapter discusses the transformation of traditional bookkeeping systems into management information systems through the use of time-sharing computer systems, highlighting the challenges and benefits of such conversions. It uses Dartmouth's accounting system as a case study to illustrate how systems designed for one purpose, such as auditing and compliance, may fail to meet other important needs like budgeting and long-range planning. The author emphasizes Herbert Simon's idea that effective information systems should provide only the minimal necessary information to aid decision-making, and advocates for computer systems that can monitor and summarize data to alert management to potential financial issues proactively.

The chapter discusses the feasibility of widespread computer terminals in homes by 1990, focusing on the technical and infrastructural challenges of servicing millions of users through regional centers. It evaluates memory capacity as manageable with contemporary technology but highlights communication infrastructure as a significant challenge, illustrated by the experience with telephone line demands at the Kiewit Computation Center. The author predicts that computer communication will eventually exceed the load of all telephone calls combined.

This chapter provides a detailed index and reference notes related to the development and application of computers in society, highlighting key topics such as programming languages (BASIC, FORTRAN, COBOL), time-sharing systems, computer networks, and computer-aided instruction. It also references influential figures and institutions, illustrating the historical context and technological advancements that underpin the computerized society. The chapter emphasizes the integration of computers into various domains including education, payroll automation, and information retrieval.

This chapter provides an extensive index of key topics, institutions, technologies, and figures related to the development and societal impact of computers. It highlights foundational concepts such as man-computer relationships, time-sharing systems, memory, and software, while also addressing broader issues like invasion of privacy and the symbiotic evolution between humans and computers. The chapter situates computing within historical contexts, referencing the Manhattan Project, John von Neumann's contributions, and advances in peripheral devices and processing speed.
