Excerpt from Spectrum of Computer Systems
The diagram (exhibit 1) represents a continmnlwith each of the arbitrary points identified shading in to others on the line. In generai it is probably fair to say that as one moves to the right the cost and complexity of the hardware/software system increase and the man/machine interaction becomes higher. The software (execu tive routine) becomes more complex as the computer is given the task of allocating its own facilities in an effort to remove the human operating element and increase the'speed. Thus the executive becomes more complex as the response time is reduced and the efficiency of the main processor becomes greater. In practice, however, the response time is always situationally oriented and is a function of such things as the number of users on-line at the time; type of request; size of the data files; and so forth.

Verkäuferbewertung 4 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book presents a novel framework to classify computer systems based on the system's hardware/software rather than the specific applications or speed at which they are computing. The author argues that categorizing systems based on the problems they solve can lead to misunderstandings and incorrect assumptions about a system's functions. The author provides a continuum with five levels of system capability. Batch processing is the simplest and least efficient, followed by remote batch input, multiprogramming, and enquiry systems. The most sophisticated and efficient system is the time-sharing system (CTSS). Each of these systems is defined and compared to other systems on the continuum. In addition to defining and comparing these systems, the author also discusses the major attributes of each system, such as conversationality, real-time capabilities, and complexity of the operating system. The author also provides examples of how each type of system can be used and discusses the advantages and disadvantages of each system. This book is a valuable resource for anyone who wants to understand the different types of computer systems and how they are used. The author's clear and concise writing style makes this book accessible to readers of all levels of technical expertise. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
