Cybernetics is the study of control, communications and information processing within systems of all kind, biological, technological and social. The word cybernetics comes from the Greek word meaning “governance” or “to steer, navigate or govern”. Cybernetic systems use information and communications processes to guide a system in the direction of the set of environmental parameters that are best suited for maintenance homeostasis and functionality.

The primary object of study within cybernetics are control systems that are regulated by feedback loops. Feedback loops are a fundamental object of study within cybernetics in that they are accountable for the process of regulation within all control systems. Examples of cybernetic systems include the regulatory units to chemical processing plants, the human body, governments, etc.
