There are different ways of defining the elements that make up an operating model. People, process and technology is one commonly used definition, [1] process, organization and technology is another. [2] An organization is a complex system for delivering value. An operating model breaks this system into components, showing how it works.
A software system is a system of intercommunicating components based on software forming part of a computer system (a combination of hardware and software). It "consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system".
The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
For example, an information system might provide information for a non-overlapping work system, as happens when a commercial marketing survey provides information to a firm's marketing managers In other cases, an information system may be an integral part of a work system, as happens in highly automated manufacturing and in ecommerce web sites.
Systems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. [ 2 ] A common type of systems modeling is function modeling , with specific techniques such as the Functional Flow Block Diagram and IDEF0 .
The implementation of threads and processes differs from one operating system to another, but in most cases, a thread is contained inside a process. templating : In an o/s context, templating refers to creating a single virtual machine image as a guest operating system, then saving it as a tool for multiple running virtual machines (Gagne, 2012 ...
The operating system holds most of this information about active processes in data structures called process control blocks. Any subset of the resources, typically at least the processor state, may be associated with each of the process' threads in operating systems that support threads or child processes.
Top level Configuration Management Activity model. Configuration management (CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
