A. UNDERSTANDING THE SYSTEMDefinition of the system in general:-A collection of parts that work together to achieve the same goalExamples1. solar system2. planning system3. transport system4. automotive systems5. information systems6. computerized systemetc.-A collection of objects that relate to and interact with each other and the relationship between objects can be viewed as a single unit designed to achieve one goal.Thus the system can be defined as a set or a set of elements and variables are organized each other, interact with each other and depend on each other.The basicThe system consists of                         INPUT ----------------------PROCESS ----- --------------------OUTPUT
B. SYSTEM CHARACTERISTICSIn order to understand or develop a system, it is necessary to distinguish the elements of the system that shape it. Here are the characteristics of the system can distinguish a system with other systems:1. Limits  depiction of an element or elements which are included inin the system and which are outside the system2.  Environmental everything outside the system, an environment that provides the assumptions,constraints and input to a system3.  input of resources (data, raw materials, energy equipment) from the environmentconsumed and manipulated by a system4.  output resources or products (information, reports, documents, display screencomputers, materials to be) provided for by the system environmentactivity in one system5.  Component activities or processes within a systemtransform inputs into semi-finished (output). This componentcan be a subsystem6. Liaison  place where the system or component and its environment to meet orinteract7.  storage area controlled and used for temporary and permanent storage of information, energy and raw materials.
