Basic Elements of System
A basic configuration of system consists of following elements; Input element , Transformation process, and Output element. Additionally, some systems have feedback loop , Control mechanism , and Objectives. Input resources are transformed into output resources. The resources flow from the input element, through the transformation element , and to the output element . A control
mechanism monitors the transformation process to ensure that the system meets its objectives. The control mechanism is connected to the resource flow by means of a feedback loop, which obtains information from the system output and makes it available to the control mechanism.
