Discuss the different types of System?

Ans.: Types of System :

Physical or Abstract : Physical system is tangible entities that may be static or dynamic in nature. Abstract system is conceptual or non-physical. The abstract is conceptualization of physical situations.

Open and Closed : An open system continually interacts with its environment. It receives input from the outside and delivers output to outside. A closed system is isolated from environment influences.
Sub System and Super System : Each system is part of a large system. The business firm is viewed as the system or total system when focus is on production, distribution of goal and sources of profit and income. The total system consists of all the objects, attributes and relationship necessary to accomplish an objective given a number of constraints.
Sub systems are the smaller systems within a system. Super system denotes extremely large and complex system.

Permanent and Temporary System : A permanent system is a system enduring for a time span that is long relative to the operation of human. Temporary system is one having a short time span.

Natural and Man Made System : System which is made by man is called man made system. Systems which are in the environment made by nature are called natural system.

Deterministic and Probabilistic : A Deterministic system is one in which the occurrence of all events is perfectly predictable. If we get the description of the system state at a particular time, the next state can be easily predicted.
Probabilistic system is one in which the occurrence of events cannot be perfectly predicted.

Man-made Information System : It is generally believed that the information reduces uncertainty about a state or event. An information system is the basis for interaction between the user and the analyst. It determines the nature of relationship among decision makers.
An information system may be defined as a set of devices, procedures and operating system designed around user-base criteria to produce information and communicating it to the user for planning control and performance.
