Coordinating the Machine’s Activities One of the most fundamental concepts of modern operating systems is the distinction between a program and the activity of executing a program. The former is a static set of directions‚ whereas the latter is a dynamic activity whose properties change as time progresses. The activity of executing a program under the control of the operating system is known as a process. Associated with a process is the current status of the activity‚ called the process state

Circular Flow Diagrams Introduction Money flows into and out of the economy. The circular flow diagram explains how money moves through the economic system involving households‚ businesses‚ the government‚ and foreign agents (Editorial Board‚ 2011). Circular flow diagrams are visual models that show firms who employ workers‚ the workers then spend on goods produced by firms‚ and the money is then used to compensate the worker and buy raw materials to make the goods and the circle continues.

Week 1-Discussion 1-Circular Flow Diagram To first explain how the circular flow diagram relates to the current economic situation‚ one must realize that the two‚ three‚ and four sector models no longer apply to the United States any more. Only the five sector model currently applies. The five sector model of the circular flow of income is a more realistic representation of the economy and has a more definitive look as to what and how economics really is in the world. In the more simplistic two

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

4.6.2 Class Diagram: • In software engineering‚ a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes‚ their attributes‚ operations (or methods)‚ and the relationships among objects. • The class diagram is the main building block of object oriented modeling. • It is used both for general conceptual modeling of the systematic of the application‚ and for detailed modeling translating
