Abstract
The chapter is devoted to the main objects that will be discussed in this book (structures, systems, processes) in the field of computing. A brief review has been made, starting from specifying the role of “information” and “information processing,” in order to specify the place of the technological environment for the implementation of information processes and to define its main functionalities. Given that the technological environment is a computer implementation, the two basic levels are presented – high user level (macro-level) and low internal machine level (micro-level) with an initial formalization of basic system resources. The main object of analysis is the performance with its factors (performance indices) which are defined and which have an impact on the workload of the computing environment based on input workflow. In this respect, a formal description of workload and specifying the role of the process profile are presented. In addition, a formalization of information technology is presented.
