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 general 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.
