Model Type

Interaction model
System context model

Description

A structural model that demonstrates the other systems in the environment of the system being developed
A dynamic model that shows how the system interacts with its environment as it is used

Correct Answer

(1) System context model,A structural model that demonstrates the other systems in the environment of the system being developed
(2) Interaction model,A dynamic model that shows how the system interacts with its environment as it is used

Explanation

A system context model is a structural model - it shows the other systems in the environment of the system being developed (e.g., the weather station context diagram showing the Control system, Weather information system, and Satellite). An interaction model is a dynamic model - it shows how the system interacts with its environment as it is used, and can be represented using use cases.
