Question

Types of system in system analysis and design

Answer 1

Answer:

Types of Systems

Physical systems are tangible entities. We can touch and feel them.

Physical System may be static or dynamic in nature.

Abstract systems are non-physical entities or conceptual that may be formulas, representation or model of a real system.

Answer 2

There are 4 types of systems analysis and classifications :

• Physical or abstract systems:

In operation, the tangible entities that may be static or dynamic are called physical systems and abstract systems are conceptual entities with no physical existence such as a formula of relationship.

• Open or closed systems :

An open system is a system that is very interactive with its environment ie it takes input and gives output frequently while closed systems are very isolated and are very rare in reality.

• Deterministic or probabilistic systems:

Deterministic systems outcomes are perfectly predictable while probabilistic st=ystems outcomes cannot be predicted at all.

• Man-made information systems:

. An information system provides the basis for interaction between the analyst and the user.
