Systems :)

System is a word used to define a set of components which interact and function between them. One of the main characteristics of a system is that it acts in a predictable way and is composed by:

• Inputs
• Outputs
• Flows
• Storages
• Sources
• Sinks

 Systems can be classified into 3 different categories:

•  Open System: Materials and Energy are exchanged across the boundaries of the system.
•  Closed  System: Energy is exchanged across the boundaries but matter is not
•   Isolated System: Neither matter nor energy is exchanged.
