Not all Systems are dynamic, but dynamics can happen in a System. System as a series of interrelated elemental units so that changes in one element will change the whole System. Associated with dynamics, there is an open and closed system. A closed system is a system that is responsive to changes beginning from within the System. Open system is a System that not only reponsif from within, but also from environment around. The structure of a System consists of its constituents, rules governing certain inputs into the System, and the information required for the System to apply the rules. System Administration creates feedback that changes the structure of the System.... so is our future policy, hopefully your day will be better.. thanks
